Title: RuiDeng Riden RD6006 DC power supply
Post by: maukka on August 28, 2019, 06:32:51 am
Ruideng (https://rdtech.aliexpress.com/store/923042), which manufactures that neat DP-series of DC power supply modules just teased their first big box DC power supply. Doesn't come with an AC-DC power supply so you have to source your own. Hope Dave will get to try and burn up this one too.

Saw this posted on Twitter earlier, and I almost replied to them saying please don't spam the EEVblog forums about it.   :-DD
It does look good.  Much more useable than the older models, but it is still a SMPS so maybe not for any low noise work.

Yeah but look at that screen setting: 65V 6A!
Get a second low current linear supply for anything low noise.

Yeah but look at that screen setting: 65V 6A!

The model number implies operation up to 60V and 6A.  I think 65V is just the required input voltage with some headroom.  I'm guessing it is buck topolgy not buck/boost.

We don't yet know if it is rated for 360W continuous, and I somehow doubt it will be.

You will need to source your own 65V 400W? PSU of the correct dimensions - all yet to be confirmed - but that isn't a common voltage.  Commonly available 48V PSUs (eg Meanwell) can usually only be adjusted about +/-15% (~56V).

I have 2 of the DP50V5A and 2 x DPH5005, but I rarely use the RD units due to having at least a dozen other lab supplies in the workshop (either full linear, or hybrid SMPS/linear).  This is largely in part to having poor UX and requiring external power source.

This new model potentially addresses the biggest issues, so it will be interesting to see what they release.  I was thinking about getting the DPS5020 for occasional high current applications, but may wait to see what comes...

If you can change the PSU from that brand to a quality one like Delta or Emerson I don't see why it could not be a competent product. Only if the controller itself is sh#t...

Usually some folks relate  price to quality...

and for my personal past experience...
price does not always means quality...

very frequently .. not even "good" stuff.

Some marketing folks deposit to the BRAND
the faith of the product as being good.

it just don't fit real world use

Just to let folks know there is 30% off this RD6006 on banggood for the next 2 and half days.

I ordered one (and the case with the hardware set and the switching power supply) on the basis its better than nothing.

The big question is, is it better than a Korad KD3005P? (or KD3305P if you buy 2)

They are simlar in price. Its pretty much 60v vs. 30v and switched vs. linear.

This is a video (from the link in the TS) with some performance testing.
Noise is about 30-50mV pp.
Too bad they don't show a plot of potential V overshoot when turning on.

This may sound "hatred" or else... whatever,

There is a single one shot solution to your problem:
- DITCH WINDOWS.
- You no longer will need not even one anti virus.
- Your apps have more than 80% chance they will run just fine in Wine
- You probably will put the manufacturer in this direction as well

and they may take the same sane decision.

Hopefully.

Title: Re: RuiDeng Riden RD6006 DC power supply
Post by: sn4k3 on November 19, 2019, 04:31:42 am
Got my today. Time to have some fun  :-+

Assembled and initial test
First note: This model GUI/layout is a 1000% improvement over DPS series.
Assembly:
+ Good and safe package
+ Housing is compact and well built, it's all to size and aligned
+ Stackable design
+ Manual is clear, all steps are there but could be better, for example put the screw image near the step, so we don't have to scroll up and down on PDF
+ Simple and fast assembly, everything is plug and screw type, no soldering needed
+ I check every crimp, they are crimped correctly and will not slide away, also they are isolated with the plastic sleeve
+ Rubber feet contain inside a metal washer in middle
+ RD fans are passive up to some temperature or amperage, so silent operation most of the time
+ Chassis is earthed by PSU screws, good continuity, almost no resistence
+ Used cables seens ok for the requirements
+ Lightweight (This is not necessary good)
- The DC cables that connect to the buck PWR IN are the only cable not crimped, they use soldered wires to screw to the terminal
- On PSU mount area i got some kind of double tape, not very sticky, not straight, applied bent tape over tape, looks like a mistake and they don't care to replace. Not needed anyway.
- My PSU fan is always on beside the note on top says "Fan have On/Off circuit" - not true, maybe they have speed over temperature adjustment but not ON/OFF, not loud but will disturb. Yours also too?
- AC switch on back - I hate this since i have large workbench with stacks of equipment’s and reach back mean get up, try to not hit stuff put my hand on back and find the switch. I know this simplify the build and cables routes but worth the effort and extra! Also, i don't like have power equipment’s always on, on stand-by, if i leave i want them dead, not sleeping waiting for a disaster to happen. Fortunately, i have a power extension on my side with some free sockets, each socket have independent switch so I can use that to fix the problem.
- MicroUSB instead of Type-C, not critical, we know is cheaper and easier. Better microusb then bad implemented Type-C.
- USB at front, we can hit the cable and it will stay at front of stuff, that kind of stuff should be hidden at back, we know module can be used alone, but a addon board could be made and with a flat ribbon cable connect from back to front to use with this enclosures.


GUI/Interface:
+ A very big improvement over last model and beat many professional models out there
+ In general it's very easy to operate, every function is a pleasure to use.
+ Very easy to set desired voltage, click V-SET, type the volts eg: “5” button, click “ENTER” and is SET. You can also use the encoder to increase the values but that is slow and unpractical to me when you want go fast, many PSU still use the encoder only and arrow keys to set V and I which i dislike a lot, for example sigilent spd1305x.
+ Recals and saves are fast to set (3 button clicks), in comparison my sigilent spd1305x is a pain to do that and I avoid that function at all cost. With RD6006 is a heaven recalling.
+ Setting page allow you to customize important stuff, like Power on behavior, confirm before recall and save, power on behavior after recall, get rid of boot logo to instant boot times, select from wifi, usb, mute beeps, brightness.
+ Firmware upgradable over USB, no more board hacking
- Add a option to click and hold some key to switch between graph mode and normal mode -- Very usefull shortcut! eg. click and hold ENTER?
- Add a option to auto shutdown after x seconds on idle state, doesn’t hurt to have this as a optional option.
- Make use of press and hold to access recalls, lock/unlock, access settings, maybe add this option on settings and replace the need of shift by push and hold?
- When you recall a preset it show at bottom the number - That's ok, but when you change your output that should put an * near to indicate changes was made. Also when you save the preset it will stay showing the last recall, that's also wrong, should show last save slot instead because we are now using that slot. Eg: Recall M2, change output, Save to M3 -- This should put M3 at bottom and not stay at M2
- keypad follow PC keyboard numbering, personally i prefer phone pattern for this aplication (1 top left first, 2, 3)
- LCD show V and I below. But on GUI buttons that's other way, first button set I and second set V, that's a big no sense to me, if you look LCD and naturally press the key your brain will move you to the wrong button to follow the LCD pattern, even if you read button label fast you may go wrong button - This need training for me.
- Green terminal for battery charging, big mistake, I bet someone at any time will use this as Earth. Worse when is Positive rail! They should put that as a red like color, an orange for example. Also why not include a earth terminal too?
-> As a feature request would like to see RGB on I-SET and V-SET, and set them RED when OVP and OCP kicks in

App Software:
+ Both PC and android app works fine to me, no virus detected by Kaspersky.
+ Software is responsive and easy to use
+ Can upgrade firmware via software, with check update function
+ Doesn't require ugly dependencies and services, work as portable
+ Almost every feature is avaliable there, beside some settings on menu page
+ Software show both normal view and power curve
- When using comunication this will lock physical access to the GUI, would be nice to operate both and sync


So far I only had time to play with user interface, no test made to performance or ripple yet. If things match up to specs this will be a winner product. No regrets so far.


EDIT: 20/11/2019
Battery Charging:

Tested some basic charging with Pb batteries 12V and ion cells 4.2v
At charge levels it behave like any other commun PSU but:

+ Fault detection, when shorting the output turn OFF and stay, to continue you need to turn on manually again
+ If voltage falls to abnormal value or disconnect a wire the output turns OFF and stay, to continue you need to turn on manually again
+ If you reverse the poles on battery connector while output is ON nothing happens, no power draw
+ When you set a voltage lower than battery source and turn on output it automatically turns off the output
+ When charge ends (at very low mA), output turns off
+ If you turn on output without a battery and then connect to battery output turns OFF, because of abnormal voltage detection, so you need to connect battery first and turn output after, nice one
+ If output is ON using battery connector, probes disconnected there's no flow (OL at voltmeter), it need to detect some source of positive voltage before start to flow current
+ While output is off using normal connection +V it show current battery voltage, this is not true if you use battery connector
- While output is off using normal connection +V, if you connect battery on reverse poles it shows 0V 3A draw and start falling down to 0 overtime (This happen with 18650 ion but not with Pb showing 0V 0.085A and fixed there)
- While output is off and connect a battery it won't show battery voltage like the V+ connector, but will show the voltage near battery icon overtime with a scroll
- When a battery is detected (Volts) battery icon turns red, why not green if ok and red if reverse connected?
- If you change voltage while charging, it will accept and continue, bad thing, so you can charge ion at 4.2V and then set 6V that will bypass. Please fix this! turn output off when change voltage in battery mode to be safe and let user turn output ON again

So this battery output is a win when using batteries, is there to be used so make use of it. The protections make sense and are always a plus.

It really looks 100% improvement although
the DPS series has a much smaller footprint
which allows even double units in a single house...

Looks good

Its very clear in the sales listing what you get: https://www.banggood.com/RD6006RD6006-W-Digital-Control-Switch-Adjustable-Power-Supply-DC-Stabilized-Power-Adapter-Buck-Module-Monitoring-Power-Supply-p-1587151.html (https://www.banggood.com/RD6006RD6006-W-Digital-Control-Switch-Adjustable-Power-Supply-DC-Stabilized-Power-Adapter-Buck-Module-Monitoring-Power-Supply-p-1587151.html)

You choose either:
- Front face portion (with or without wifi)
- Metal case (includes power jack, fan, cables, etc.)
- Standalone fixed 110/220V power supply (just a generic one)

Manual here: www.ruidengkeji.com/inst/RD6006.pdf (http://www.ruidengkeji.com/inst/RD6006.pdf)

One weird thing to me is the green terminal is "Battery charging" NOT earth ground. There is no provision to connect earth that I see, so this might cause some confusion. Would be nice if they had made it Yellow or another color than green (but the feature idea is good).

edit: sn4k3 stated this above already.

I had to buy 3 separate items: PSU + RD6006-W + Case.
You can see assembly manual, everything there was included.
You also need CR1220 Button Cell Batteries if you want the clock function, not included!

DPS series smaller, but at cost of very bad UI, it take ages (lot of steps) to do stuff there. Of course if you want portability and use the unit time a time the DPS can come handy, still for me is a downgrade when you can go RD6006 right now.
If on bench you can stack RD6006 up to the units you want, while DPS can became unstable up to some units due lack of base area

Also getting flagged as virus "Trojan:Win32/Fuerboos.A!cl". I've emailed RD tech to see if they can provide a standalone exe or something instead.

"Measure" setting in the options has low/med/high in terms of update rate, but it acts as a filter. I had it set on Low and when turning on the output the numbers would slowly increase, really it was not slow. Change the 'measure' mode to Fast and it will be more realistic. BTW quite impressed at the LCD update rate they get with STM32F103 and this high res screen.

https://www.youtube.com/watch?v=51fAQbQGGqI (https://www.youtube.com/watch?v=51fAQbQGGqI)

He seems to have measured a 200mV drop on the output at 3A load, can anyone else confirm this? I'll have to test it tomorrow.
If that is the case its been suggested in the comments they might be measuring the output prior to the 10A fuse (10mOhm+) and sense resistors (15mOhm).

edit: I'm not seeing any significant drop at 3A output (10s of mV), so it might be a measurement issue?

edit: I'm not seeing any significant drop at 3A output (10s of mV), so it might be a measurement issue?
From what I can see in his video, he has 1 of his voltmeter leads plugged in the powersupply (piggyback), and the other one piggybacked in the amp meter.
So his volt monitoring goes through 1 testlead that carries the current (you cant see the testleads in the video, but the way the 4mm jacks are plugged this is imho the only possible way).
This is of course not the best way to monitor the voltage, especially if you detect a voltage drop.
The voltage leads should have been plugged in the psu first and the current leads to the load piggybacked on that.

Can you measure if there's a voltage drop on your unit at 6A? (I dont know if you have an electronic load or beefy resistor that can handle that at a representative voltage)



Also, in de SDG video he talks about that there is a double height case for fitting 2 rd6006. But I cant find anything on banggood or aliexpress. Only a shallow depth case that can only fit the front panel (so without power supply).
Does anyone knows what he is talking about or have a link to that dual height case?

Can't find it either, maybe not released yet.
You can also buy 2 x the current product, expensiver but more power as it use two power supply instead of 1 to feed the modules

Can't find it either, maybe not released yet.

Did you get any chance to measure the noise under high load with your DSO?
I saw in that other video that noise can go up to 100mVPP, but more as a verification.
I also wonder if the switched power supply itself is part of that noise aspect, or does it all come from the buck converter. Does that even work that way? (noise in->noise out) (have you measured that?).
If it comes from the internal psu module the noise could be lowered with some capacitors.

I'm in the process of choosing a dual bench power supply (budget about €250,-) and I cant decide between 2 of these or a Korad KA3305P
The Korad is linear so probably less noise and is about the same cost. The big disadvantage with the Korad is that it's big and bench space is always limited.
And of course it doesn't have a display mode where you see a graph. That's only via the software.

I also like the Ah meter on the rd6006. Does that also work in non battery mode? (I believe I did saw it work).
And if so, when does it reset? when you turn the output off and on again?
And is it possible to not have that Ah meter periodically change on the display with temp and Wh? (I dont think so)

What I don't understand with the video review of SDG is that he calls it a "Programmable Bench PSU"
But what exactly is programmable? I don't think that you can program it to give different voltages or currents for certain periods of time. Like you can with for instance the korad or a siglent spd3303. I thought that that made it a "programmable" PSU? :-//

The voltage leads should have been plugged in the psu first and the current leads to the load piggybacked on that.

Can you measure if there's a voltage drop on your unit at 6A? (I dont know if you have an electronic load or beefy resistor that can handle that at a representative voltage)

Yes his wiring is wrong as you point out, but then in the comments I saw he said he's fixed the wiring and measured the same thing. So not sure what is different with his setup.
I tried 5V 6A output and there was only ~8mV drop, which is very good. So they are clearly measuring at the output or compensating for it.

Did you get any chance to measure the noise under high load with your DSO?
I saw in that other video that noise can go up to 100mVPP, but more as a verification.
I also wonder if the switched power supply itself is part of that noise aspect, or does it all come from the buck converter. Does that even work that way? (noise in->noise out) (have you measured that?).
If it comes from the internal psu module the noise could be lowered with some capacitors.

I'm seeing some 100mV p-p spikes on the output for 5V 6A out, but not really any ripple. My equipment isn't great for low noise though.

The supply used to power the RD will of course add to the output noise, but it goes through some filtering steps (common mode inductor and capacitor on input). If it was a really nasty supply you could add more filtering to the output.

I also like the Ah meter on the rd6006. Does that also work in non battery mode? (I believe I did saw it work).
And if so, when does it reset? when you turn the output off and on again?
And is it possible to not have that Ah meter periodically change on the display with temp and Wh? (I dont think so)

Its always running. It is reset when the power supply is turned off then on (not affected by output off/on). Maybe there is another way to reset it (can check the manual).

What I don't understand with the video review of SDG is that he calls it a "Programmable Bench PSU"
But what exactly is programmable? I don't think that you can program it to give different voltages or currents for certain periods of time. Like you can with for instance the korad or a siglent spd3303. I thought that that made it a "programmable" PSU? :-//

Programmable is just controllable, it doesn't necessarily mean any sort of timing commands (although that feature may be nice). You can control this unit via PC.

Thanks for all the answers.
That its not programmable in steps versus time looks like a missed chance. In the video's I can see that when voltage or current is set with the PC, the RD6006 follows almost instantly, so lag isn't an issue.
With programmable PSU's like the korad's it's also all done from the PC software, so to have the PSU act as a 'programmable' psu that does voltage or current steps versus time it has to be connected to the PC.
Imho something like that could have been possible too for the RD6006
Do you know how the link between PC and RD6006 works? I have no experience with any of these PSU and am a bit of a noob, so is there something like a standardized protocol for this that the RD6006 might also work with the korad software?
The korad protocol is defined here (https://sigrok.org/wiki/Korad_KAxxxxP_series#Protocol) and is basically serial over usb, so it probably shows up as a serial2usb converter in the windows hardware manager.

I found this new video that shows a bit more of the pcb's:

If there is demand they might add it to the firmware, but IMO its going to be easier to write a script on the PC which does the timing control you want.

So the connection between PC and RD6006 is via USB serial adapter, it will show up as a standard COM port to send commands to. The protocol will be somewhat standard (voltage = x, current = y) but its likely not compatible with other units. I don't see any command documentation so it would be necessary to sniff the commands sent by the RD software. You could ask them if they will supply it.

This is different to say LXI or SCPI implementation from higher end power supplies, where there are clearly defined standard commands.

Most of the ones on that list have obscure protocols. You'll even see their older series the DPS on there which has a bespoke protocol, Sigrok rely on users making and submitting decoders for every device. The closest we have to a unified protocol is SCPI (https://en.wikipedia.org/wiki/Standard_Commands_for_Programmable_Instruments) but hardly anything uses it

it  even looks the similar situation of EDA formats.
EDIF was introduced as a common denominator so that
all other formats would be (in theory) translated to/from.

Hardly nobody cares about EDIF and each EDA promotes their
own.. they don't like each other and never will.

But in hardware.. things may have a bottom line where having
90% of the work done (in sigrok) who cares which protocol is used?
The hardware owner may have a larger and more interested user base...

By having sigrok as the bottom line for their (open) protocols

Hopefully... but the picture is much more like EDA software.

Voltage wise you just need to have it generate 1 or 2 volts extra for headroom and have access to the reference voltage. For a linear current regulation you could set the switching current limit a little higher and either burn up the difference or have a boost stage to put it back into the main power supply capacitors. Either way the feedback loop is none of your concern, just need enough headroom both for voltage and current.

Hi,
this looks like a nice PSU. I especially like the fact that it is not very deep as I don't have the depth on my workbench that most other bench PSUs require.

Before I buy I have a few questions that hopefully people who already have it can answer.

- If I buy 2 of these and connect them to the same AC-DC PSU, can I connect their GNDs together so that I can, for example, have 5V and 12V supplies with common ground? Is the input GND the same as the output GND?

- Can the Windows desktop app for these PSUs connect via the WiFi module? O is WiFi only for the smartphone app and desktop needs to connect via USB?

- Can the Windows desktop app handle more than one PSU at the same time?

Thanks in advance!
Chris

If you have the same ac/dc supply supplying both you already have a common ground, in fact, you have no choice.

Don't use the windows app, it's probably some heuristics from them developing with all chinese products but that doesn't mean they aren't real. Alternatively do it in a VM. Maybe someone who has it could do that. I'm going to guess one instance of the application is good for 1 supply but maybe they were optimistic and you can use multiple(all the wifi probably have the same setup though).

Got the parts and assembled it tonight.
Got the recommended AC power supply from the Aliexpress posting. And despite having a sticker next to the fan saying the PSU have built-in fan on-off control the bloody fan runs all the time. With the case on, the noice was even worse.

Since I'm not ever going to be pushing 300 watts through this PSU in my litte lab, I just disconnected the fan, and now its nice and quiet. Taped the internal temperature probe to the case of the AC Power brick, so I can monitor it's temperature on the display. Also attached the sensor of the little board controlling the case fan to the PSU, so it'll turn on if the metal gets hot.
If it dies because if this it's just 30 bucks after all, and peace of mind / lack of fan noice is worth it.

I have now received 2 of these PSUs and a 48V 10A PSU to feed them both. I'm still not sure that I can use the 2 outputs with common GND. I measured resistance between the input and output GNDs of one PSU and I get just over 8Mohm. So it seems that the input GND is not the same as output GND. Before I try connecting both output GNDs and set fire to it (I don't have an explosion containment pie-dish  ;D ) can someone please confirm that this is still OK to do?

Thanks,

Hello,

(A) Before connecting both output GND together without any resistor, you might test with a 1000 ohm resistor and a ampmeter between these two GNDs, then replace it by a 100ohm, a 10ohm, a 1ohm resistor, and finish without any resistor.

You stop if there is unexpected current through the ampmeter, and I think you detect this unexpected current before breaking any component.

(B) You might also add one diode after the output(+) of each PSU, in order to avoid current going from the highest tension  output (12V by example) to lower positive output (the other PSU at 5V by example) in the wrong sens. In a simple PSU, current must goes out from (+) to GND and never goes in the other way inside the PSU.

Have a nice day !

OK, I'm clearly missing some knowledge here. I measured the resistance between the GND of both PSUs (when the AC-DC PSU feeding them both was off). The result was tens of Mohm (this seems to go down the longer I measure).

When I switch on the PSUs and then measure the voltage between the 2 GNDs I get 0.00V. When I set one PSU to 5V output and then take my meter and hold the positive probe to the output of that PSU but the negative probe to the GND of the *other* PSU I measure exactly 5V.

It's as if the GNDs become "connected" only when the PSUs are on.

I received mine yesterday. I have quite a few nice bench supplies, but they are all decently sized, very capable units that if I wanted to power something elsewhere in the house were less convenient to lug around. I have been on the search to something portable to augment my bench. When I saw the video pop up reviewing this (and other mentions around the net), I liked the fairly polished design with ok specifications, and when I looked at the cases available, the large one was very boring to me, but the short one for an external PSU was nicely size to grab with one hand. A careful look at the dimensions and pictures, convinced me that I could probably fit a 2"x4" PSU module, a traditional AC inlet, and an additional tiny fan. As you shall see, things didn't quite work out that way, but it's very close. Plus with modern power electronics, I could get a 150-200W (depending on airflow) 48W PSU (Meanwell EPP-200-48), which is more than enough for my normal needs (<24V, which should give me the full 6A at all lower voltages).
From the front it looks pretty normal, although I did turn the PSU up to 50V so if need be I could hit 48V.
[attach=5]
However, a quick look at the rear shows that things are not as they seemed. This was the most time consuming part and the panel cutout is not perfect as I do not have much in the way of metal working tools, and did this with a nibbler.
[attach=1]
I am fairly happy with how the inside layout turned out, although it would have been greatly improved by having the proper wire colors. You can see that I chose to not mount the fan internally. It didn't fit with enough clearance to make me happy around the PSU in its intended location, so I had planned to mount it to the far side panel, but the 12V fan rail on the PSU does not appear to agree with the fan load (and the PSU buzzes), at least at the light loads I expect to use this at almost exclusively. For now I have removed the fan, and I may revisit this in the future. You can also see I epoxied the temperature sensor to the PSU heatsink so I can at least monitor the PSU temperature. Despite perspective claiming otherwise, there's quite a bit of clearance between the PSU and everything else internal.
[attach=2]
Here is a close up of the side of the PSU so you can see the earth grounding strap and extra insulator plastic. I imagine 3D printed PLA is probably not ideal here, but as I have a large gap, and an earthed chassis, it probably doesn't need to perform to the absolute maximum isolation performance). I did check, and after removing some paint, the chassis is properly earthed. Not easily visible, but part of the other safety features, the IEC320-C14 inlet does have an integrated fuse.
[attach=3]
And finally, I did have to modify a foot due to poor planning by having the screw mount for the PSU side of area used by the rubber foot.
[attach=4]

While I was searching for this thread to write this post I found another poster who had a similar idea. https://www.eevblog.com/forum/chat/show-your-favorite-and-mostly-used-benchtop-psu/msg2826078/#msg2826078 (https://www.eevblog.com/forum/chat/show-your-favorite-and-mostly-used-benchtop-psu/msg2826078/#msg2826078)

On a different note, to anybody who was planning on writing their own control software and didn't feel like reverse engineering the app, here is some preliminary mapping of the modbus register space.

I found the ones for the DPS5005, etc, and based on that tried reading the registers. The register map is very different, but I found most of the settings I was expecting to find, and those that I cared to find. It looks like the memory settings block is fairly similar to the block as used by the DPS series, but the earlier addresses are all changed. I also did not trigger various faults to see where they mapped. If anybody does have an official document describing the map, or any further results, I'd love to hear about it.

The AC/DC 48V PSU is external. I 3D-printed brackets to screw it to the bottom of my workbench.

Hi,
I would like to get back to this question:
- If I buy 2 of these and connect them to the same AC-DC PSU, can I connect their GNDs together so that I can, for example, have 5V and 12V supplies with common ground? Is the input GND the same as the output GND?

I have now received 2 of these PSUs and a 48V 10A PSU to feed them both. I'm still not sure that I can use the 2 outputs with common GND. I measured resistance between the input and output GNDs of one PSU and I get just over 8Mohm. So it seems that the input GND is not the same as output GND. Before I try connecting both output GNDs and set fire to it (I don't have an explosion containment pie-dish  ;D ) can someone please confirm that this is still OK to do?

Thanks,
Chris

OK, I'm clearly missing some knowledge here. I measured the resistance between the GND of both PSUs (when the AC-DC PSU feeding them both was off). The result was tens of Mohm (this seems to go down the longer I measure).

When I switch on the PSUs and then measure the voltage between the 2 GNDs I get 0.00V. When I set one PSU to 5V output and then take my meter and hold the positive probe to the output of that PSU but the negative probe to the GND of the *other* PSU I measure exactly 5V.

It's as if the GNDs become "connected" only when the PSUs are on.

Im also planning to use 3 of these (with a common GND!) I actually linked two together (sharing output ground). Although i can get two separate voltages from each supply using the same GND but i can see that there is a current leakage on the two units so they report the incorrect current.

So yes, two together can work but they are designed to be used standalone as it has floating outputs.
My crazy idea... Generate the schematic for the main top board and see if its possible to somehow modify the board to enable a common ground. If additional components are required then might have to respin a new board with ground sharing yet maintaining all the original functionality.

I like this supply because of the short case option and I put a nice Meanwell 120W (50v @2.5A - with no cooling required) inside the small box!

The two binding posts on the back of the unit are for the purpose of connecting it directly to two other units. At the moment the solution is no so ideal because of the current leakage problem. I have had two linked up for a week (low voltage/current) and haven't seen any magic smoke yet!

What MeanWell PSU model is that?

I used this one from digikey:
1866-RPS-120S-48-ND - there is also a non "medical grade" version thats a bit cheaper
You will also need the mating connector and pins:
455-1133-1-ND
455-1184-ND
455-1185-ND

I initially used a din rail supply that also fit inside but it made a bit of a squealing noise which was kinda annoying, but this one is really quiet.

Also when you mount the supply you can use a longer screw for one of the rubber feet and there is actually another hole already which line up exactly with the supply. So in the end you should only need to drill 2 holes and use the two existing holes to mount the supply.

Excellent choice, MeanWell's medical PSUs are rock solid.
Thank you also for the connector references, I might buy a bag or two of those from eBay.

Do note they recommend a common mode ferrite choke on the output for radiated EMI reduction, although it's arguably minimal. Winding the output wires four to six times will be plenty if you add a ferrite core, though.

I needed something with high efficiency that outputs 5V to power some controllers and a RPi inside an enclosure that will control relay outputs and other things.

I should have known this would be getting discussed here :)

I have extended the CLI version out with --gui here https://github.com/Black-FX/rdserialtool/tree/add_gui (https://github.com/Black-FX/rdserialtool/tree/add_gui)

It adds a basic Tk GUI like (click the voltage or current to turn output on, scroll wheels on them to change):

(https://github.com/Black-FX/rdserialtool/raw/add_gui/gui.gif)

The biggest issue at all seems to be that once the serial connection is connected, the screen lock engages - when the register is set to disable it, it is simply ignored.

I also managed to sniff this URL from the windows app

http://www.ruidengkeji.com/rdupdate/ (http://www.ruidengkeji.com/rdupdate/)

It has the firmware files and software, It appears there was an RD60061 and so this is the 60062 (beta maybe). Unfortunately the firmware is compressed so I can't find anything useful there.

It appears the M# isn't revealed by the device. I have walked through 0x00 - 0xFF looking for changes after loading a stored preset and can find nothing.

Also the following registers
Code: [Select]
0x05 - Internal Temperature C
0x07 - Internal Temperature F
0x20 - Battery Connected
0x21 - Battery Voltage (x 10mV)
0x23 - External Temperature C
0x25 - External Temperature F
0x42 - Mem Ok - Confirm loading stored profiles.
0x43 - Mem Out - Auto enable output when you load a stored profile.
0x44 - Boot Power On
0x45 - Buzzer
0x46 - Logo
0x47 - Language: 0 = Eng, 1 = Chinese, 2 = German, 3 = French - But it only allows you to set 0 or 1 via Modbus

There will be more, namely the calibration data and the details for the wifi - I don't have the wifi dongle so can't test (any volunteers?)

Noise is just terrible in my view. Dave discovered that at 5V these produce 500mV p-t-p noise!!! Not suitable for RF

All RuiDeng needs is to start developing newer type that with linear pre-regulator, assuming they have decent analog designer to make a good one while reasonably cheap.

It really would be fair (for all those who bought the switching back-end) to see the same capacitor bank used to filter out it's noise.  Perhaps 1 or 2 NTC thermistors could be used to gracefully power-up that many caps?

Can you quote some specific loads and p-p ripple voltages please?
In the other thread (https://www.eevblog.com/forum/blog/eevblog-1265-$53-360w-lab-bench-psu!/) I measured <160mV at 5Vout 5A peak (full BW), with the actual ripple being much lower. Dave measured ~100mV p-p at 6A.

If I limit bandwidth to 20MHz then I see a bit less than what Dave did, 80mV p-p at 6A 5V out. But my source PSU is only 30V, so that may be the reason.

I'm not convinced my source PSU is adding significant noise to the signal, these switching spikes are entirely from the RD unit. I have not watched your video yet though to see what supply you are using.

Thats not my vid - just one I found on youtube :)

He was seeing I think 6v p-t-p at 58v/6a (I think he made the same mistake as Dave initially so his readings are 10x off) on the SMPS, and then 300mV p-t-p with the linear supply. If he is off by a factor of 10 as Dave was at first, then his measurements should probably be 600mV and 30mV respectively. I am a total n00b when it comes to measuring the high frequency noise like this - so I could be talking out my ass :)

@BlackFX - Thanks for the link anyway, these things are getting popular. In my post I mentioned a varistor feeding a cap bank that sits between both smps's (that should have been an inrush limiter, so the back-end doesn't shut-down on start-up)  |O

What are the chances both SMPS's are interacting with each other to produce these results?

I am thinking that I will just use a current limiting resistor on the input and then shunt it with a relay once the bank is charged.

Earlier in the thread yesyes was talking about how they appear to use a low side switch to disconnect the output, rather than a high side switch.
So you are probably seeing a little bit of leakage from the input voltage to that terminal, and measuring that. I don't have mine in front of me at the moment, otherwise I'd test that myself.

I was thinking little, as in just enough current that you'd see it on the volt meter, but not enough to actually register if something was connected. Just like how it'd pretty easy to measure a volt or two AC on unconnected leads. After seeing the second picture, I'd agree about that being an issue. As to why it's 60V, that's suspiciously close to the input voltage it measures on the psu as shown in your screenshot. I definitely should check mine, and see what it's doing next time I'm can.

You could always make the same measurement between each of the output terminals of the AC PSU and real ground when you have it wired up the same way as in the chassis. My gut feeling is that won't show anything unusual but my gut feeling was that your earlier post was a non-issue, so take that with a grain of salt.
Does the 60V go away when you switch the output on the rd6006 on?

Post by: AlexFerro on January 24, 2020, 06:10:30 am
Looking closer at your first picture, it actually looks like the rd6006 output was at -60V relative to earth ground. That would mean that the screw is shorting the *positive* output to earth ground, which would be a significantly bigger problem than it shorting the negative to earth unintentionally (lots of good reasons to either intentionally of course), especially with this power supply. It's up to you if you think that the PSU doing this is indicative of a poor design, and thus that trusting it to be safe and keep working is a bad idea, or if you can safely add some extra insulation around the screws.

Although my unit(s) will be powered by a beefy 500VA 7Kg linear back-end (https://www.eevblog.com/forum/beginners/transfo-lamination-bolts-super-hot-at-20-min-and-no-load-why/), I'd still be interested to see noise measurements with CY1/2 removed on that Banggood provided SMPS.

 How this work setting current limiting low (100/200ma) with  high load (for example trying to search a shorted component)? It's stable? Any overshot at power on?
Thanks!

To get the desktop app to work over a wired network connection is fiddly but doable.

First you have to set the PSU up as per the limited instructions using the mobile app. Be warned its buggy...

It looks like the PSU sets up a hidden WiFi access point. You configure the mobile app with your network name and password of your router and then let it connect to the PSU to pass the login information. You must have location services switched on or the app will crash on an iOS device

the IP address which the app uses is the IP address of the device you are working from. The PSU seems to uses this IP address to make a connection "to" the application

Once the information has been passed, it looks like the PSU then sets up a connection to your router and waits for the App to connect to it (No idea why it needs IP address of your mobile device)

The mobile device should now connect and work nicely.

Now, if you want your desktop application to connect to the PSU, switch off your mobile device and change the IP address of your desktop to that which the mobile device was using before you switched it off  and hey presto, the desktop app now connects to the PSU using the wired network connection.

If anyone from RIDEN is reading this, PLEEEEEASE look at this and change the setup to allow easy connection from a wired desktop device!!!

And please, if anyone knows another way, please share

That sounds like a right old mess, I had assumed it was simply MODBUS over TCP/IP - the USB is MODBUS/USB.

Thanks!

They seem pretty stable. As for overshoot - my simple setup can't measure much, 0.31% for 9v / 375ma into a 24ohm load and 0.82% when the power supply goes into constant current when it's set to 100ma.

Here it is into a 1ohm resistor. The constant current kicks in and clamps the voltage - 100mA was clamping at 90mV and I was having a hard time capturing it; So I did it at 200mA

An output relay would be nice to stop those power on spikes. For the sudden load test in cc, until there are capacitors on the output, there would be always an overshot. Also some linear supplies have this problem, quite normal on an smps one. I not know how the  better/$$$ units handle this.
In any case in this price range i think that is still quite impressive...

It was the screw length ?

So what happens to a battery when, or if, the serial link disconnects?
I think it would be great to ask Riden to make a future revisions in the ST uC code so that if selected from a timeout menu, it would act like a watch-dog timer. Eg: if no serial commands are received every x seconds, the output switches off for safety.
Any thoughts? Because it's unlikely Riden will open-source all their code.

Hello..

I have to buy a complete RD6006 Kit (Joy-IT RD6006) from reichelt in germany.

(https://www.mikrocontroller.net/attachment/446253/JT-RD6006.JPG)

The kit (Reichelt article number JOY-IT RD6006 S2) contains the following parts:
JT-RD6006 (control instrument)
JT-RD6006-Case1 (comfort case)
JT-RD6006-Con (WiFi module)
JT-RD6006-NT (power supply)

Link: https://www.reichelt.de/rd-labornetzgeraet-0-60-v-0-6-a-comfort-set-joy-it-rd6006-s2-p273625.html?r=1 (https://www.reichelt.de/rd-labornetzgeraet-0-60-v-0-6-a-comfort-set-joy-it-rd6006-s2-p273625.html?r=1)

What I find very interesting is the type of ventilation in here
the video by Jerry Walker is shown. It has the power supply cover
removed and the fan removed. Since the removed power supply fan
is larger than the supplied case fan, this was on the
Screwed back of the housing and with the control electronics in the
Power supply connected.

Link to the video: Youtube video "Riden RD6006 Power Supply Part1"


In addition to the Joy-IT RD6006 kit, I also have an electronic one
Load (max. 150 watts) ordered (see picture). Then I can do that
Test the power and stability of the power supply.

Part 2: power measurement and temperature
https://youtu.be/f44B7oMN_IQ (https://youtu.be/f44B7oMN_IQ)

Part 3: The third part about the RD6006 power supply is about Rippel and Noise
https://youtu.be/oIgDpWblxkM (https://youtu.be/oIgDpWblxkM)

Rippel and noise is an annoying topic for switching power supplies. Depending on
Design, the developers manage to keep the interference voltage to a minimum
to reduce. But a certain amount of ripple in the
Unfortunately, output voltage always remains.

In circuit developments in the audio area and laboratory there is a linear one
PSU better fiddled. A good linear power supply, for example the Rigol DP711
have a residual ripple of <500 µVrms / 3 compared to the RD6006
mVpp. The RD6006 is suitable due to its high ripple (loud
Manufacturer about 100mVpp) not necessarily for that.


When looking at test reports on Youtube, I'm on one
interesting video by Hannes Jochriem. Among other things, he tests the
Function of current and voltage limitation with an LED on a Rohde
& Black DC power supply. The LED gets when the output is switched on
briefly a voltage spike of 10 volts (1st picture). Not really
advantageous for the LED.

I have the whole thing with my RD6006 and a red LED without
Series resistor tested. I set 10 volts and 20mA on the RD6006
(see 2nd picture). Then I have the reverse experiment with 2.5 volts and
1A made (3rd picture). The LED passed both tests well. One + for
the RD6006 :))

Hey,
I just got mine and I must say it works pretty well for such a small device.

I didn't receive my C14 inlet and will probably add a small fan somewhere if I can make it fit.

I use a Mean Well EPP-500-54 power supply. This allows to output about 54V.

Hallo

Yes.. its a great DIY power supply  :-+  But with big noise and ripple :(

I am planning to convert the RD6006 to a linear power supply.

The components for my linear power supply are:

- Toroidal transformer, 160 VA, 2x 15 V, 2x 5.33 A
- Bridge rectifier, 600 V, 8 A
- 2x electrolytic capacitor, radial, 4.7 mF, 63 V, RM 10, 85 ° C, 2000h, 20%
- BDW 83C Darlington transistor, NPN, 100V, 15A, 150W, TO-3PN
- V 4329H profile heatsink for power transistor, 75x120x32mm, 2.0K / W
- µA 723 DIL voltage regulator, adjustable, 2 ... 37 V, DIL-14
and other.

RD6006 Linear version 30VDC/5A
(https://www.mikrocontroller.net/attachment/447697/20200306_163156.jpg)


My idea is to convert the RD6006 controller so that it DC voltage regulated  linearly by the power supply (see picture).
An LM723 is said to be used for current and voltage control. The RD6006 Controller should take over the digital control of the LM723.
Therefore the RD6006 controller must be a little bit modified to hard-. and software.
LCD and key controls remain.

Yes, I have had that problem also while having a unit on all day while developing some electronics. The power supply was set at 5v and was drawing about 100mA. Its very random though, occasionally 3 times in a day sometimes none. I dont have the wifi module or the little battery plugged in but I do have the temp sensor plugged in.
My power supply powering is a MeanWell medical grade supply. 50v out @ 2.5a.

Hello friends

I have now converted the RD6006 into a linear power supply. The power is 32V and 3.5A. The RD6006 controller takes over the digital control of voltage and current.  For the current limitation I use the BAT connector. A short positive voltage pulse on this line switches the RD6006 power supply output into OFF-Mode ("ON/OFF" button goes off). For air cooling, I use the included temperature control and a quiet 80x80mm fan from Noctua.

Hi, there.

I have now installed the transformer voltage switch. The
Switching works from 15V and switches the voltage from 15VAC to
30VAC over.

RD6006 linear power circuit
(https://i.ibb.co/s9Yhrvm/RD6006-Lin-09.jpg)

(https://i.ibb.co/gSk5L4x/20200401-150835.jpg)

A problem occurred with the voltage regulation on the RD6006 controller.
The controller internally checks the input voltage on the "voltage sens" line
and limits the control to this voltage.

I have disconnected this line in the controller and the rectified
Transformer voltage of 43V via a voltage divider on this line
laid. The controller now also shows the
transformer voltage to 15VAC the maximum transformer voltage of 43V and can
can be regulated from 0-42V without problems.

What may follow is the separation of the output voltage via a
Relay. This prevents an unwanted switch-on pulse at the output.

Hello friends  of electronics :D

I have optimized the circuit a little bit. So for example the adjustment is
of the actual and nominal voltage is no longer necessary. The equivalent stress
now comes out of the controller (voltage sens).

(https://i.ibb.co/mJqyfqZ/RD6006-Lin-10.jpg)

Because the output always had 50mV less voltage than the set
value at the controller, I have the voltage at the negated input of IC1a
with resistance R3 increased by 50mV.

Remotely I have exchanged the two operational amplifiers CA3130 against a TL072
types are exchanged (see picture).

Greeting Rolf

Addendum: R2 is not correct. It's reading 10K ohms.

One more small correction  ???

The voltage from the "voltage sens" circuit (R16+R17) does not go on
the "voltage sens" Pin12 of K1 but to the "power supply sens" Pin10
of K1 in the RD6006 controller (see picture).

Hi, everybody...

There's another problem that's been bothering me a little. In my circuit.
the current limiting circuit only reacts after a delay time
of about 1-2 seconds. Sensitive components can sometimes break down
go.

For this reason I would like to improve the circuit a little. It should be...
react immediately and block the power transistor so that no
voltage is more present at the output. Furthermore the output should automatically
switched off (by a long positive pulse level), which it
after a time delay.

Let's see if we can do it with a few components.

Until then, best regards. Rolf

solution...

To solve the problem, I have created a monostable flip-flop
from IC X1b and X1c into the "current protection" circuit.

(https://i.ibb.co/Fbhb2RR/RD6006-Lin-13.jpg)

The flip-flop has the task of transmitting the positive pulse from IC1b
(current monitor) to approx. 2 sec. and thus extend the
Disable power transistor via diode D8 for this time.
At the same time a pulse is sent to the "BAT" connector in the RD6006 controller
is sent for the output to be switched off.

The output or the voltage can be switched off easily with the "ON/OFF" button
can be switched on again.

Hello, everybody.

The installation is almost complete. I just need to drill the holes for the
Drill holes in the bottom of the housing to fix the circuit boards.

I have made a few measurements before. The ripple and noise was
at a load of 10V/3A over 560mVpp (see 1.picture). But this was due to
the too high capacitance of C7 in the negative feedback circuit of IC1a. To
some tests with smaller capacitor values and a
series resistor with 680pF in the negative feedback circuit I have
and noise to a value of 40mVpp (2.picture).

Regarding ripple and noise measurement on the RD6006, I would like to add one
very interesting video by Jerry Walker. It shows two
RD6006 power supply versions. The top device is with a
Switching power supply and the lower one with a linear power supply.

The measurements can be seen in the video from 29:30 min. First the RD6006 with
Switching power supply and then the modified version with linear power supply.

Link: https://youtu.be/NHN1z1N7QvU?t=1770

My ripple and noise measurements at maximum load (32V / 3.2A) showed
a maximum Vpp value of 29mV and a VRMS value of 2.5mV
(3rd picture).

No load

The Jerry Walker conversion only applies to the power supply. The

I would leave a step-down pulse converter, and put a linear regulator at the output. For the linear stabilizer to work, it is necessary to raise the pulse output by 2-3V relative to the required output voltage. This would solve the problem of large power dissipation on the regulating transistor in linear mode.

Therefore I would have to change the firmware in the RD6006 controller.  :phew:

One thing that drives me crazy is having to reach around the back of my stacked instruments to turn off the power. Just using the standby switch on the front of the RD6006 leaves the 60VDC supply on and that wastes some power so I always use the rear switch to turn it totally off. My solution to what I considered a problem was to add a switch to the front panel that is in series with the switch on the back and this added switch completely removes power from the 60VDC supply. There is almost no extra space on the front so I had to be creative.

It did require some careful modifications that I didn't find too bad but I don't take any responsibility for anyone else who might try this. The 3 photos show the mechanical modifications I had to make. First I cut off and removed the top plastic retaining tab on the front panel. This was necessary to give me enough side clearance so the switch wouldn't hit the flex circuit going to the display. The remaining bottom tab holds the front panel tight enough in the metal frame. With the tab removed I had a perfectly sized cutout area for the switch. I had to clip out a short narrow section of the circuit board that just had some of the ground plane on it and that short piece of the circuit board would have interfered with mounting the switch. I then carefully calculated where to drill the mounting hole for the switch. The switch I used was a C&K 7101 SPDT series. Next I soldered and put heat-shrink tubing on the two long leads going to the back of the case. Because the front panel is plastic I also soldered a wire to the side of the switch to ground it in case there was any breakdown in the switch insulation that could pose a safety hazard.

The photos should clearly show what I have described. While the switch on the back might not bother most people, I feel much better having the added switch on the front.

Post by: ArthurDent on May 10, 2020, 05:59:50 pm
Rolfdegen brings up a valid point.

I live in the United States where the mains voltage is 120VAC and the switch I used is rated to handle that voltage. I don't believe you could find a switch that size to handle 240VAC so you would have to do things a little differently if you lived in 240VAC areas. On my HP53132A counter I faced the same problem and didn't have enough space behind the front panel to mount a switch. What I did was similar to what a lot of equipment makers have done in the past. I used a stiff custom bent metal rod (a piece of coat hanger wire) to activate a larger properly rated push button toggle switch mounted further back in the case. The hole in the front panel and the clipped out section of circuit board would still have to be done but the plastic mounting clip on the RD6006 front panel could stay. You'd just have to fashion a proper mounting bracket for whatever switch you choose.

Here are photos of the HP53132A modification I made. The rod had to be bent to clear the prescaler and is coupled to the switch shaft with a piece of plastic air hose like you'd use in a fish tank. Making the modification this way would eliminate any concern about using a small switch no matter what your mains voltage is.

Hello..

During my last measurements I used the my power supply circuit input on to Siglent SPD3303X laboratory
power supply. The Siglent laboratory power supply had very low ripples and
Noise. For this reason, I have the power supply circuit again under real conditions
tested on a toroidal transformer.

Now I have connected the power supply circuit to a toroidal transformer with 160VA 2x15V / 5A
to measure the Rippel & Noise. I only used a transformer winding with 15VCA for the measurement.
According to the data sheet, the LM317HV can handle a maximum input voltage of 60V. With a change
voltage of 2x15VAC, the voltage at the rectifier is 42V. A standard type of the LM317
only tolerates 40V.

circuit
(https://i.ibb.co/THFbd8R/Power-Supply-Trafo.jpg)

With an output load of 3A and 10Volt I have a Rippel & Noise of 2Vpp on the rectifier
measured. The LM317HV has a ripple rejection ratio of typically 65dB (factor 1778) power
Adam Riese at the output of the regulator approx. 1mV Rippel & Noise. According to the data sheet, you can use the ripple
Improve & Noise with a 10uF electrolytic capacitor at the adj connector of the controller to a maximum of 80dB (factor 10,000).

It is recommended to add a resistor of 2.2KOhm to the power supply output,

Hello..

My power supply circuit with the LM317 has a little problem. she can
are not readily reduced to 0 volts. Try the
Output voltage at the ADJ pin with an OpAmp and negative operating voltages was not very special
successful.

For this reason, I continued to look for another solution.
The following power supply circuit comes from ELV and controls the
Power transistors with a constant current source (R1, R2, R3 and T1).
This allows the output voltage from 0-30V to be easily via a
Standard operational amplifier IC3 and IC4 with + -5V supply voltage
regulate.

The special thing about the circuit is the separate power supply for
Control and load circuit as well as current and voltage control via one
Microcontroller.

I was particularly interested in the control loop for the output voltage, because
I want to control it via the RD6006 controller. The circuit did
I built it on a test board. As a power transistor, I have
used a 2N6284 Darlington transistor. The operating voltage of
+ 32V + 5V and the control voltage of 0-2.0 volts provided a siglent
SPD3303X laboratory power supply. The negative supply voltage for the
Operational amplifier supplied an LT1054 voltage converter.

Mains differences are :
- price 110eur (for RD6006) and 150eur (for RD6012)
- weight 607g and 642g. The heaviest is maybe more durable, for the same current load, at about 4A.
- ammeter resolution : 1mA and 10mA. Do you use this 1mA resolution inside a power supply ? I can read multimeter-ammeter data on my laptop.
- current charge, low limit is 10mA and 100mA. Is this function useful ? low limit 100mA seems very high ?
Are both a tension consign and a current consign not suffisant  in order to charge a battery (with a diode) ?
- noise output tension : 100mV and 250mV ?
Lower is better ! but I don't know if theses values create issues that I can't solve with a electrolytic capacity (often 100µF), I don't play with RF.
- fan start condition higher for the RD6012 : 4A and 8A.

Do you have any advice for an hobby use.

Price 100+ EUR is probably for the whole kit including the module itself, power supply and enclosure

Regarding charge termination current, 100mA is more useful as for most Li-Ion of reasonable capacity it is close to datasheet values. 10 mA is way too low. But this should be a setting, not a hardcoded parameter.

Ripple and noise to an RD6012 is very high 250mV. I build a new power supply with PPS 5330 power board and RD6006 controller. I change the PPS Pannel to RD6006 pannel without Step Up converter.

Hello

I recorded my test circuit once. Q2 is the
Constant current source and ensures that the power transistor Q1
is opened. The operational amplifier X2 controls the diode D11
Current flow at the base of Q1. If the control voltage Vctrl at X3
the output voltage at X2 drops less and thus the current flow
the basis of Q1. Part of the control current now flows through the diode
D11 and the output of X2. If the control voltage is 0V, the
complete current through D11 and closes the power transistor Q1.

(https://i.ibb.co/3BCbZ8C/ELV-01.jpg)

The operational amplifiers are operated with an operating voltage of + -5V
provided. The LT1054 generates the necessary -5V. I am aware of
decided for a transformer with one winding, because I also have the
RD6006 controller must supply a positive voltage.

What you have to pay attention to is the following: The GND potential of the
Control electronics is not connected to the -pole of the output voltage,
especially with the + pole of the output voltage. If not, then
the circuit does not work.

My next step ..

I actually wanted the necessary components for the power supply separately
to order. But only the costs for the hollow-rib fan unit
were already around 70 euros. And if you still have a suitable housing
and if you add the necessary small items, you can quickly get to 100 euros
or more.

For this reason, I chose a complete power supply kit
PPS5330 decided by ELV. This kit contains everything I need
my RD6006 power supply including housing. The complete control
of the PPS5330 power supply is then taken over by the RD6006 controller
USB and WLAN interface. The whole thing could look like this (1st picture).
Maybe I'll make a new front panel too.

Hello..

Great joy and a little disappointment. The power supply kit from ELV
arrived today and I can use the long weekend to
Solder circuit boards and then assemble the power supply.

Unfortunately, when unpacking, I found that the front frame
something is bent. However, I think I have the front frame again

So .. base board works.
It was a bit difficult to assemble the cooling unit and attach the
Power transistors including white hands from the thermal paste ..
But everything worked out with a little patience and calm.

PPS 5330 Basic board and transformer
(https://i.ibb.co/gzJYXWG/Basis-Platine2.jpg)

To test the function of the basic board without the front board (MCU), I did
two separate control voltages of 0-5 volts on the connection pins
U target and I target placed. I was then able to release current and voltage
to adjust.

PPS 5330 Basic board circuit
(https://i.ibb.co/B37WYXQ/ELV-Power-02.jpg)

I did a short stress test. Voltage and current are
stable. So far everything is ok. The cooling unit gets evenly warm.

The next step is to solder the front panel and install it in the
Casing.

Hello all,
Has anyone been able to get the keypad unlocked while communicating over serial. The RD6006 seems to ignore the keyboard lock register when communicating over serial. It doesn't make much sense to me why they would perma-lock the keypad while communicating over serial. Any ideas to get the keypad function while communicating?
Thanks!

This blocks is made inside firmware, any received command on serial port (WIFI/TTL) will lock the keypad for some time...
Cause the software make requests continuously, so you get locked keypad until stop the software.
There is no simple ways to change it, only if patch the firmware.


I recovered firmware source code of RD6006...
Here is my beta version, if anyone interested.
https://mega.nz/file/ZW5CwYTA#jnOAoec-fOpXhUFWO4UaH2lWeLCYNT0LEmase0Oa9aM (https://mega.nz/file/ZW5CwYTA#jnOAoec-fOpXhUFWO4UaH2lWeLCYNT0LEmase0Oa9aM)
You can always return to stock firmware at anytime.

RD60062_V1.28.1.bin - my custom beta firmware.
RD60062_V1.28.bin - original (stock) firmware.

Still have some limits!
Cause I still didn't debug WIFI initialization, so temporary just disable that code. So WIFI will not work!
Maybe in future I will add it (if anyone will need it)...

What was changed:
The menu was complete remade, now I can easy add new items.
And now it looks better:
(https://i.ibb.co/6yDq7cM/4.png)

SHIFT + Left/Right — switches the current style (without save in settings)
(if need to set style after power on, then can do it over settings menu, as before).
For 'style 1', can be enabled/disabled items.
(https://i.ibb.co/Jjz1ytG/5.png)
(https://i.ibb.co/jM00Lss/2.png)

Other Styles:
(https://i.ibb.co/stBkbhn/1.png)

(https://i.ibb.co/C9KNkrF/3.png)
(https://i.ibb.co/K70fYzM/6.png)

Added OPP (Over Power Protection).
SHIFT + MEM — used to setup OPP
OVP, OCP, OPP — now can be disabled by setting it to 0
When entering OVP, OCP, OPP, SHIFT button will be highlighted as well
(to visually distinguish input: V-SET from OVP, I-SET from OCP).
The RIGHT button now works as a Backspace when typing.

When turned on the internal fan (the one that is on the module itself), icon will be displayed.

Hi UniSoft!

Your work looks impressive!

Is it also possible to add a setting for current cutoff in battery charger mode? In the original firmware, preset value of 10mA is not very useful, it would be really nice to have possibility to set the limit as needed

Title: Re: RuiDeng Riden RD6006 DC power supply
Post by: elektrolitr on June 26, 2020, 06:04:44 pm
That's great!

I think you can make the setting range equal to the whole current range here (can't do too much harm with setting too big). It is also good to have this value visible on screen (maybe dedicated screen layout for charging batteries with all relevant settings and measurements- V-set, I-set, I-off, Ah, Wh, battery temperature). The value of battery voltage in RD6006 is meaningless, it's just the output voltage reduced by a fixed bias (0.05V IIRC), so no much sense to display it (IMO).

As an absolute extra I could imagine to have an additional setting to turn charging off if the battery temp exceeds the set value. But it's not that important.

The source code would fit really well on github, if it isn't already and if you have time/want to. I'm sure once people have a base they would happily contribute to it. Really cool project overall! ;D As for the keypad, any chance you could patch the firmware to enable the keypad while communicating with the computer? Or would something bad happen? Thanks!

Can you now fix that display layout so it's readable ? The UI definitely needs space inbetween the 3 main lines (V / A / W), 50% of the line height is a good value, and smaller characters.

I don't understand what exactly you want to get.
50% of the line height is 30px (for large digits), notice menu items is 24px,
what for you want so large spaces?
Now large numbers is 32x64px ('.' (dot) is a half width, ie 16x64),
But resolution of display is too small, so developers draw this lines at 0,60,120 (so 4px overlapped).

Oh looking back at the EEVBlog review, it was actually him who said this, at 10 minutes in. He says, "The colour coding doesn't make much sense e.g Purple for input voltage and output power." Basically the coloring of different things on the menu seem a tad random. It's really isn't a huge deal, though, more of a stylistic thing I suppose. I installed the latest version of your custom firmware and the units for each of the outputs seems to be below the number, for example the V doesn't align with the numbers, but it's slightly below. I don't know if this was on purpose or not and it's stylistic, so it doesn't matter that much.

The reason I am asking for it is I see it as the biggest problem in terms of user interface; in the original UI the lines are too close together and difficult to read. Line spacing of 150% (character height + 50% space) is close to the optimal value. See here more details:

https://www.justinmind.com/blog/best-ux-practices-for-line-spacing/ (https://www.justinmind.com/blog/best-ux-practices-for-line-spacing/)

I think 48x24 characters at the same 0, 60, 120 lines would make this much easier to read. See quick attempt in Paint:

Earlier in the thread, @BlackFX confirms the cause as being a mounting screw on the SMPS shorting the +VE output to the chassis ground.
Seems to imply that the power supply front panel -VE was at a potential of -58v.

Seems to imply that the power supply front panel -VE was at a potential of -58v.
At least thats what I understood...

Spot on, there is a screw that fouls the main output cap on the SMPS I am using. You will see I later repaired the damage.

This guy had the same issue but discovered it before any magic smoke :)

Any chance getting the TTL (interface) mode working?  Front USB connector is less than ideal (and doesn't appear to be isolated?), so ability to connect isolated USB to TTL-serial adapter to the connector at the back (for the WiFi module)  would be really nice.
TTL should work.
Protocol (Modbus) is the same for all interfaces...

There seems to be some kind of bug, if interface is changed to "TTL" it works, but after unit has been powered off and on again, unit doesn't respond to modbus queries anymore...
However, unit will start responding after one goes to the communication settings and to the interface menu option (no need to actually change the value...seems to be enough just scroll down to the menu option and then exit out from the menu....

The Wifi connection doesn't seem to be working for me... Is this a bug or am I doing something wrong?
To answer your question, at least I need to know what exactly you did, step by step.
In the meantime, I can only guess.

--- How to use WiFi ---

-- If WIFI still not configured

1. You need select WIFI interface in menu. exit menu (settings saved only after exit from menu)
2. Restart device (use Power button)
3. Now you will see red string: Server IP: ---.---.---.---
4. Run App (Note: both device must be in the same network)
5. In app click on sandwich, and in menu "Network distribution", it will wait for RD6006
6. After some time RD6006 will change the string to the yellow, which contains IP, and one more string "Connecting wifi...."
    If this not happens, search problems with network. (this is infinite loop, firmware just wait for the response from WIFI module).
7. in App click Next, end enter password, click confirm
8. Done, this steps need to make only once

-- If WIFI already configured

Run App first (it is working as a server), then start RD6006.

Okay, it's kind of hard to explain, but I'll try. When I power on the RD6006 the Server IP is already yellow without me doing anything. Then I try to connect to it in the app, and the RD6006 changes to "connecting wifi", but before it can actually connect it goes into the RD6006 main screen without connecting.

So, your RD6006 WIFI already configured (assigned IP).
You no need click connect in the app at this moment, just app must be started!
Check that IP addresses is the same... otherwise reconfigure.
(in this screenshot can see that RD6006 can't connect to the server, cause I didn't run the App)

Hi,

would it be possible to get a different mode for the wifi? It is a bit inconvenient, that the device wants to connect to the application. I would be better, if the device is the server and applications can connect to it. Or would it be easier to attach a esp-01 with esplink or something like that to the wifi header and use ttl mode? Is there anywhere a pinout of the wifi header?

Thank,

Not!
Yes, I agree it is a strange logic...
I just assume that the developers did not want to implement WIFI scanning, setting the login and password.
---
Physically, this is possible.
But need write the firmware for the Wi-Fi module itself (all logic implemented there).
And, accordingly, another application.

Or would it be easier to attach a esp-01 with esplink or something like that to the wifi header and use ttl mode? Is there anywhere a pinout of the wifi header?
Yes you can use TTL mode. But the App will not work.
pinout can see on pcb.

Hi,

There are now 2 RD power supplies. The first one at 6A max and the new one at 12A. Abilities are very close.


I'm also curious about the practical differences between RD6006 (https://www.aliexpress.com/item/4000282551930.html) and RD6012 (https://www.aliexpress.com/item/4001053200176.html) for embedded design / hobbyist use.

Here are the specs I care about. According to the datasheet (https://drive.google.com/file/d/1Y1qyeIMnJPQ3lg1phi0J0_khPrc45HH3):

I have 2 questions:

My full desire is to get the beefier "frontend" and upgrade the supply as needed.

Post by: thm_w on July 03, 2020, 11:58:30 pm
I have 2 questions:
  • Could the RD6012 current set & measure resolution be tweaked to match like the RD6006? Or is it hardwired that way to map the ADC to the gruntier current capacity?
  • For output at or below 6A (upper limit for RD6006) is there reason to believe ripple would be worse on the RD6012 than the RD6006? Re-read the datasheet. RD6012 is indeed 2.5x the output ripple @ 6A  :(

My full desire is to get the beefier "frontend" and upgrade the supply as needed.

- Patrick

You are doing embedded design, there should be almost zero need for a 6A+ supply. If you need it you will know already (eg high power motors, etc.).
The ADC resolution is most likely hardwired, as you say, you have to map it to a wider range.

UniSoft fantastic work.

Quick question about what can be change, would it be possible to change the behavior of the power button when you power it off?
At the moment it keeps pulsating that is quite annoying (at least for me), I'd mind having it staying lit but in a constant dim state not pulsating.

Cheers!


PS: I never understand why come companies don't provide ways for anyone to develop on top of their hardware they would benefit soo much from it.

Yep, just turn off LCD, LEDs, Output, and also programmatically generates a pulsating PWM,
waiting for the Power button to be pressed, then restarts the controller (via software reset).
I think it is possible to slightly reduce consumption by turning off unnecessary peripherals,
switching unnecessary ports to analog mode, lowering the clock frequency (or maybe
even completely turning off the generator and switching to the internal RC generator).

Thanks UniSoft for sharing WiFi firmware. It doesn't look like bootable image tho. My module just spits garbage over UART. Also file header seems to be invalid according to https://github.com/espressif/esptool/wiki/Firmware-Image-Format#firmware-image-format

Anyway, I hooked up to UART on the module header and noticed it uses AT commands for communication. After further digging I learned that Espressif is releasing AT firmware for their modules. It's usually used to add WiFi functionality to Arduino. It looks like the WiFi module is nothing more than a ESP8266 with a standard AT firmware. I don't think they did anything custom.

I still haven't been able to make it work because of the crappy iPhone app which is not detecting server IP correctly but this seems to be the app issue. I will try Windows app later.

I think it can be safely assumed that you can get off the shelf ESP8266 (2$, I paid even less) to make yourself a WiFi module with 3.3V regulator and a few resistors. If you want to do that here is the schematics someone reverse engineered: https://cuttlefishblacknet.wordpress.com/2020/03/01/riden-rd6006-wifi/

No need to pay higher price for the WiFi module, especially if you have ESP8266 laying around!

Thanks! Seems to be correct file - 4MB. I will flash my ESP later today.

UPDATE: I can confirm Windows software works with standard ESP AT firmware. It's not really needed to flash dumped image. I can't say it's 100% compatible but I didn't find anything what wasn't working. I suppose mobile app will work as well but iOS version is broken so I couldn't test it.

The best part is that most ESP8266 modules come with AT firmware preinstalled so there is no need to use serial converter and wasting time on flashing. Just build the circuit and connect it to the PSU - it should work right away.

If you are asking about an external thermistor, then it is used only to display the temperature and that's it.
In my firmware, I added the ability to turn off charging when the specified temperature is reached.
An internal thermistor (the one on the board near the heatsink) is used to display the system temperature, and to protect against overheating (OTP:> 80C).
The fan speed is not adjustable.

It is possible to have a case fan controlled by the external temperature probe?
It is impossible without the appropriate hardware support.
In my opinion, it is much easier to implement on some separate inexpensive MCU.
Title: Re: RuiDeng Riden RD6006 DC power supply
Post by: diogoc on August 11, 2020, 02:20:19 pm
So the heatsink fan is only ON/OFF? I thought a pwm would be used as a function of temperature.

For a case fan, a pwm output was enough to drive a fan mosfet, but it might be better to do with an external MCU.

Great work on the custom firmware!

I have a couple of suggestions :) not deal breakers but maybe some future ideas for you..

1. In 7 seg mode would be neat if the "input" "vset" etc values looks also 7 segment.

2. I have always disliked the cycling between C, Ah,and Wh on the bottom right. Would be cool to either have a cycle mode or a temp only mode. As in normal mode i'm only interested in seeing the temp at a glance.

3. This might be complex.. Mem mode is a bit tedious, you need to remember what setting each of the Mx are to save you going through them all with the shift button. So my idea was if you press any of the M[0..9] briefly, a popup will appear with all the M[0..9] volt/current settings on the screen at the same time. They would also be positioned in a way that relate to the positions of the M buttons. Then when you find your desired mem setting, you simply "press and hold"your desired M button to set the voltage/current you see on the popup that relates to that button :)

Anyway, top work!!!!!

Hello everybody,

Might someone explain ?

On the one hand RD60xx seems to have a temperature control for battery charging and on the other RD60xx doesn't have any external temperature sensor.
I don't understand how this feature is useful for charging little AA-nimh, AAA-nimh, 18650-li-ion batteries ? Temperature sensor must be right around the battery.

For very large batteries (which I don't use) must I put the RD60xx unit very close the battery I am charging ?
When battery gets tou hot, then the RD60xx heats up and stops the charge ?

Have a nice day !

There is an external temperature sensor.
But with the stock firmware it used only for display the temperature, nothing else!

Add option in firmware... (will be in the next release)
(https://i.ibb.co/gSHLzZq/sw3.jpg) (https://ibb.co/gSHLzZq)

Made output on PA14 (it comes to SWD vias, so can easy solder resistor).
There will be high level when need to turn on primary PSU.
(https://i.ibb.co/8sdpZ5v/sw4.jpg) (https://ibb.co/8sdpZ5v)

Also take 5V from this switch...
cut the track and put diodes
(https://i.ibb.co/prZs2Lr/sw5.jpg) (https://ibb.co/prZs2Lr)

Can fit in original case
use double side sticker
(https://i.ibb.co/r39Fzfd/sw6.jpg) (https://ibb.co/r39Fzfd)

Benefits: have a normal case, terminal block.
Disadvantages: very bad transformer, give not enough power to drive digital part + wifi, need at least 300mA.
But the idea itself is working!  :-+

My first post in this community so first I'd like to ask if this is the right place to ask for help with this PS. I know there is a repair category as well, but not sure if the device needs repair at all or if it's just my fault using it wrong.

I didn't use it much yet, but lately charger a super small quadcopter battery. 4.35V HV and 0.1A for a slow charge. Maybe I connected the plug to the wrong ports while having the battery on the other end, but I can't imagine of anything else that went wrong.

And this is what happens now if I want to use it: I set voltage and current, power the unit one, and the voltage falls to nearly zero, or to the voltage of the connected battery, and no current runs. If I afterwards pull one of the leads/plugs voltage shoots up into the sky and slowly settles afterwards.

Any idea what may be wrong??!?!
Thanks a lot for your help, and it this the wrong thread please let me know and I'll try to move this post.

Oh yeah. The little bugger ist busted. What's the name of these fuses? I only have glass type ones, and now need to source those new ones.
There's 10A written on them. Is this a type description, or as i assume the VALUE?

May I ask why it's a bad idea to connect a battery to BLACK/RED? As far as I understood the manual the recommend BLACK/GREEN but don't say it's mandatory.

Hopefully it's only the fuse. Keep my fingers crossed.

Thanks for the fast help and your great modded firmware. Looks excellent!!

What's the name of these fuses?
1808 125V/10A Littelfuse
When you buy a module, they usually provide a spare fuse.

May I ask why it's a bad idea to connect a battery to BLACK/RED?

NVVV S-800-70 (800W / 70V = ~11.4A)
yes this PSU is extra noisy, the fan working non stop, loud like a vacuum cleaner...

I ordered another one NVVV S-800-65 (800W / 65V = 12.3A), and today got the package, looks OK.
The fan is not working at all, if there is no load, and it really depends from temperature.

The fan is not working at all, if there is no load, and it really depends from temperature.

Fan issue aside, I’m wondering if it the 11.4A vs 12.3A difference really matters, since the total power is the same anyways (800W) and the buck converter would draw a smaller current at a higher input voltage (for a given output).

Also, I believe these supplies have adjustable output (+/- 5% or so). Would be a good idea to set the output voltage at its highest possible value, to keep the maximum current at a lower value?

The red NVVV logo trying to mimic the red MW logo of Mean Well doesn’t inspire much confidence....

@unisoft: Does your new power supply also needs to be loaded with a power resistor to prevent this high frequency noise, like the NVVV S-800-70 model?
Title: Re: RuiDeng Riden RD6006 DC power supply
Post by: trazor on September 07, 2020, 09:21:15 pm
About the fan noise... the NVVV S-800-70 consumes 12W at idle. I've attached one of these https://www.amazon.com/gp/product/B07WLTR1R4 (https://www.amazon.com/gp/product/B07WLTR1R4)

Even at a setpoint of 40C the fan turns on for some minutes every 40 minutes or so. Dissipating 12W seems to be impossible  in a box with with so much air padding.

@Unisoft. I'm running your firmware on RD6012, it is awesome, thank you. Are you releasing new builds for that hardware? I'm still using the last (and only?) BETA release posted here.
I would love to try the mod to power down PSU  to real quiescent values.
I think that other people pointed similar opinion... the original color coding is confusing. Can we have Amps, Watt and Volts with a consistent color scheme in all the interface? V is pink in the readout, but yellow in the setpoint, but blue for OVP, etc,etc. In fact, I don't think I need colors, just the positions in the screen have meaning, but if colours are used I think we can try to keep user interface calm, like any other "respected" hardware device manufacturer does.

Can you release the UI emulator? that way people can research and help you with alternatives.

I've flashed the RD6006 in my 6012 unit hoping that the firmware will auto detect hardware. Seems it isn't the case. My 6012 is capped to 6.1 Amps. May I suggest a feature to make the device (6006, 6012 or 6018) be set dynamically or at flash time?

Not bad, absolutely quiet, does not heat up at all, no high-frequency noise. There is a fuse.

@unisoft: Does your new power supply also needs to be loaded with a power resistor to prevent this high frequency noise, like the NVVV S-800-70 model?
Yes, need  :(

@UniSoft Thank you for your great work.

My thoughts:
Above 48V the state changes for CC even with no load connected.
You have the option to choose what to show in layout 1. If it was possible to choose more information?
The shift table could be a little bigger (maybe using the space on the bottom bar?)
It is possible to reduce the buzzer volume?
The M0 (default when power on) don't use the values saved, it uses the last values

Confirm... there is a bug. It depends from input voltage, when voltage set over 90% from input.
will be fixed.

You have the option to choose what to show in layout 1. If it was possible to choose more information?
sure possible.
What do you want to see there? Note It can't fit more than 6 lines.

The shift table could be a little bigger (maybe using the space on the bottom bar?)
Could be. But what for? Font (8x16) anyway will not be bigger.

It is possible to reduce the buzzer volume?
Definitely no...
It is a standalone buzzer, and control pin doesn't have PWM output.

The M0 (default when power on) don't use the values saved, it uses the last values
I have previously asked a question about the behavior of M0.
I asked what is better, to restore the last selected/active memory cell after restarting the power supply,
or when choosing a memory cell, simply copy its values to M0. People preferred copying.
Therefore, after restart the power supply, memory cell M0 will be selected and therefore the last settings will be used.
---
If anyone has better ideas, please describe them in more detail.
If people accept and support, then I will try to implement them, if possible.
This also applies to all other options and functions.

If there is only 6 lines the user can't select more than 6 values at a time.
You could add the Vbat, temp, I-off, T-off, Ah, Wh.

Just to increase the font. It is dificult to read from some distance.

If people prefer like that you can leave.
There is a write to flash/eeprom each time a new value is selected? Can't that reduce the lifetime of the memory?

OK

Just to increase the font. It is dificult to read from some distance.
There are full fonts: 8x16 and 12x24 (full ansi set)
And reduced fonts (only digits and few letters VAW...): 16x28, 32x64
8x16 is used now for table (also parameters in Layout 2), 12x24 used for menu.
There is no enough space to increase the font (maybe few pixels only, what really will not make it more readable). 

There is a write to flash/eeprom each time a new value is selected?
Yes, each time...

Can't that reduce the lifetime of the memory?
Yes, it will reduce the lifetime of the memory...
But that is FRAM (Ferroelectric Random Access Memory): MB85RC04V
Read/write endurance: 1012 times/byte.
So even if you will change settings 1000000 times per day, you can do it more than 2700 years  :-DD

Hi there,

I spent a couple of hours testing the last firmware for RD6006 V1.32.11. (I did not test the earlier versions)
First of all, congratulations, great job!
Here is my review :

1. As for me, you could remove Layout 0, since Layout 1 does the same and it is user configurable.
(just my two cents  ;D)

2. When Output voltage is set over 40V (with 1V hysteresis) the fan is forced ON, even with no load  ???

3. Some french translations could be improved.
Could we use an xml language file to customize texts?

4. BTW, I also updated the PC software to version 1.0.0.8.
The previous version had an xml file for each language (not sure it did use it though). Version 1.0.0.8 doesn't include these files.
Does anybody know if there is a way to customize the texts?

5. The sequencial LED test at startup is funny, but the sequence should definitely NOT include the |ON/OFF| button because at power ON,   
one might think that the output is briefly turned ON and OFF, which is not the case, but I get a heart attack each time!  :palm:

6. Let me tell you that you really did a very nice job!  :-+
I love the added functions
- Color selection (allows to select 1 color for Volts, 1 for Amps etc...)  :-+
- Layout selection using < > keys,  :-+
- Alternate display on status line was really annoying, plus temperature reading in °C and F didn't make any sense!
- Power button LED brightness in standby mode (the slow blinking was annoying)  :-+
- Option "Save Mult." is very handy.  :-+
- Option "Mem Hint" is handy too  :-+
- Battery charging cut off current setting is great!  :-+

Thanks for sharing your work.
 Regards.

This is a standard layout and does not interfere too much.
Let it be...  :)

2. When Output voltage is set over 40V (with 1V hysteresis) the fan is forced ON, even with no load  ???
Yes it is.
If temperature >45C or Voltage >40V or Current >4A, then turn on the fun...
If the temperature is above 45°С, or the current is above 4A, or the voltage is above 40V, then the fan turns on.
The developers decided so.
But in RD6012, the voltage check was removed.

3. Some french translations could be improved.
Could we use an xml language file to customize texts?
No.
I didn't spend time for translating, only English.
But if necessary, you can send me a text file with English text and its translation...
Just try to keep the text as short as possible, and without special characters.
This also applies to other languages. So if anyone wants to help with translation, please also write to PM (or e-mail).
Note: the character set is very limited (see attach) :(
Also, if anyone knows a good font 12x24 and 8x16, please let me know.

4. BTW, I also updated the PC software to version 1.0.0.8.
The previous version had an xml file for each language (not sure it did use it though). Version 1.0.0.8 doesn't include these files.
Does anybody know if there is a way to customize the texts?
That files was never used...
All strings are hardcoded in software.

5. The sequencial LED test at startup is funny, but the sequence should definitely NOT include the |ON/OFF| button because at power ON,   
one might think that the output is briefly turned ON and OFF, which is not the case, but I get a heart attack each time!  :palm:
OK, will change...

I'm a bit of an electronic novice so bare with me if this is a basic question.  I charged my 10S5P ebike battery pack with the charging function, I did it slowly at 1A and had the cutoff voltage set to 42v, however when I returned hours later the output voltage was 65V but 0.02A.    I'm worried it might have cooked my battery pack.  After I unplugged it I measured my battery and it measured 41.5 so it seems OK.  My question is, why would the out put voltage be so high?  Since the current was quite low should I just not worry about it?

This does not make any sense, looks like the firmware has somehow crashed... - or - your RD6006 output is fried... - or - ... I don't know  :-//
1. The satus bar shows CC mode although the actual current shows 21 mA while set to 1.000 A :o
2. Output voltage shows 65.13V when set to 42.00 V plus OVP set to 42.10 V  :o
3. Output Voltage is normally limited to 61 V  :o

- Did you connect your battery pack to the Red terminal before moving it to the Green one?
If so, maybe you killed the output MOSFET...

- Did you test your RD6006 with a "passive" load (12 V halogen light bulb for example...)?

- Are you running the stock firmware?
If using Unisoft firmware, what is the value of Vbat on Layout 2?

1. The satus bar shows CC mode although the actual current shows 21 mA while set to 1.000 A :o
Firmware have a bug with display CC, when output voltage over 90% from input...
described on previous page...
Will be fixed in update.

2. Output voltage shows 65.13V when set to 42.00 V plus OVP set to 42.10 V  :o
There is a LED connected in parallel with a fuse... So if fuse is dead the voltage will go over resistor and LED
While voltage feedback connected after the fuse, so in case of dead fuse internal logic will try to increase output voltage...
This behavior can see in video from this post:

I'm sorry I didn't notice your question until after I messed around with it for a bit.  I am and was running Unisoft firmware, I don't recall having the battery pack on the red terminal, maybe I did, I just don't recall.  I had not tested with a passive load.

Since running into this issue, every time I turn on the output, the voltage jumped up to 60+ volts.

So I did notice something else weird.  V-Set was set to 642v!  It didn't display all 3 digits that on the little screen [attach=1] but it did show up in the PC software [attach=2].


I tried changing the V-Set from the PC software and it would go back to 642v
I tried powering everything off/on, did the same thing.
I tried flashing to the latest firmware 1.32.11, still did the same thing.
I tried resetting to factory defaults ( '0' while powering on), still did the same thing.


I then, from the panel, changed the V-Set from 42v to something else and back again and that seems to have fixed my problem.  I have not tested the battery charge function yet, however it's showing (and outputting) the correct voltage now.

Thanks for everyone's tips.

I guess the voltage value in EEPROM was damaged... Due to non stable power or power off while writing... so this is possible.
1. Reflash doesn't clear settings...
2. Reset to factory defaults ( '0' while powering on), do not restore memory settings! Maybe I should add it? Also, there is no validation of values (add it now).
When you changed the V-Set, it rewrites the value in EEPROM...

@Unisoft I'm left-handed and it happened two times already that I hit the Power button while pressing shift. Can you add a feature to turn off the unit only after pressing power button for 3 seconds (or configurable time)? Also, if this displays a message similar to the lock message like 'Press Power button for 3 seconds to turn off" it will be great. Thank you! Also, can you add Tetris?  :-DD

@Unisoft, I've been testing with an RD6012W and I can confirm that WIFI works just fine, the PC software can control just as it did with the original firmware. As I had the WIFI configuration already set from original firmware, it continued to work just fine.  Even after resetting defaults via "0" press at bootup and flashing back to stock firmware.

One thing you provably already know is that the current readings on the RD6012W are way off, I imagine due to the fact that firmware is meant for 6A unit. Can you confirm?

Equally the max AMP setting for RD6012 is set to 6.2A rather than 12A, so is there a version available (or plans to release) a 12A version of your firmware?

I have also tried flashing back from PC App and from boot mode ("enter" key while powered) back and forth. Going back to original firmware requires reset setting otherwise weird things start to happen.....

As it has been said many times on this threat, BRAVO! Excellent work and excellent contribution to all of us here, very thankful we are indeed. Hopefully this kindness will be returned to you along the way.....

Here is pre-release version of the firmware for RD6006... RD60062_V1.32.12b.bin.
It is still under development...
Testing is needed.
If you have any ideas, what to add, what to fix, let me know.
I post only the firmware file itself, since this is not the final version yet.
The flasher utility can be taken from previous posts.

Whats new:
+ Fixed bugs..
+ New option "Max Power" to limit the power of primary PSU.
+ Fixed Layout 4
+ Added more options for Layout 1
+ Added function to dump the screen (make screenshots) (real dump from LCD GRAM),
  but this function a little bit slow, takes around 13-15 sec (need transfer 320*240*2 bytes over UART).
+ modified French translation (please check if all correct...)
(still need to make translations for German, and Chinese.)
+ Added Russian Language
+ Font for menu changed to Terminus (http://terminus-font.sourceforge.net/ (http://terminus-font.sourceforge.net/))
...

Feedback is welcome!

Hi there,
thanks for this update.

Already flashed  ;D

It looks good so far.

|ON/OFF| button does not flash anymore at startup  :-+

|CC| icon showing at higher voltage setting is corrected too .

French translation looks good too (noticed 2 small errors to be corrected)
- --- Paramètres --- shows strange characters
If no way to correct it, you can also spell it --- Parametres ---, it will be "Good enough for France..."  :-DD

- "Max d'énergie" could be replaced by "Puissance max"

Default max power is set to 390W how can this be? (6.1A * 61V = 372.1W) maybe I missed something....
Edit : Indeed, I DID miss that it was the power on the primary side  :palm:

Just one small problem (not sure if it is mentioned before). When I flash my RD6012 either with custom or back to standard v1.31, I cannot set splash screen anymore. All I get is black and white start screen. Not that it is important but I just want to confirm if it is me doing something wrong.

Edit: I forget to mention that this is only happened when I use newer PC Software version 1.0.0.8. If I use the older version, it can write without any problem. I guess it's just the PC app doing something wrong.

Hello first let me thank Unisoft for this amazing firmware!  ;D ;D and all you guys who have been involved on this  :box:.
I use the RD6006 mainly for charging li-ion battery packs for ebikes. With Unisoft firmware I use layout 2 and 3 (graphic representation of charging process is important to me, been using an oscilloscope previously with my dual analog homemade PS)

I have found another problem with RD6006 module regarding battery reading voltage (show 0.05v less than real voltage). I bought 2 units and this strange "glitch" happens on both units. I attached a image explaining the problem. Do you guys have the same problem? I contacted  RD RIDEN and they said it was in specs, but I wonder if it can be fixed?

It happens with stock firmwares 1.28 and 1.32. I tried Unisoft firmware and the same happens.

Thank you!

Ps. I finally joined eevblog, I'm a regular reader, learn a lot with all you guys.

Sorry for any mistakes but I'm not english native

No! Due to low resolution of ADC (12 bits).
The option Upd. R. (Update Rate) cannot in any way affect the measurement accuracy!
It is just averaging the last measurements.
UpdR=Low: averaging the last 6 measurements (sum of last 6 measurements divided by 6).
UpdR=Medium: averaging the last 3 measurements (sum of last 3 measurements divided by 3).
UpdR=High: just 1 last measurement.

I tried Unisoft firmware and the same happens.
Sure.
I used exactly the same calculations as in the stock firmware.

I think you may be expecting a little too much from a cheap power supply.

Is that device accurate?

Hi Unisoft, thank you so much for you explanation. I've been learning alot about how this device works. I can live with this limitation it's a matter of just adding 0.05v to the read value. Normally I prefer technical explanations to better understand how things are programmed rather than "it's in specs".  :-+ :-+

Sure.
I used exactly the same calculations as in the stock firmware.

I deducted that. I really like your firmware, specially the layout 2 full of information, very usefull indeed, small size font but clear readable, at least to me. I like the way you place the INPUT Voltage spliting other parameters and separated different parameters using boxes.  :-+ :-+ :-+

I've been following the discussions here for quite some while now.  I greatly appreciate that firmware updates are being made available as people discover issues.

I have what might be a silly question / comment.  Why is it not possible for these power supplies be able to have greatly increased output current when the output voltage is low.  I do get that there may be issues with dynamic range of the current sense A/D inputs but that is easily managed with suitable component changes.

My great wish is that the 6012 could have an output current rating of 20 Amps at up to 40 Vdc output and lower.  Similar wish for the 6006: 10A max output current at 40 Vdc and lower.

The bulk power supply can handle the power requirements.  It is just the 6006 / 6012 that needs a bit of tweaking.

Comments anyone?

He did a great job fine turning the stock firmware and solve most of the things I miss or dislike in this unit. What I most like is the way he gave technical explanations of how things are programmed and why some couldn't be implemented, and end with a firmware with options that help users with different wishes.  :-+ :-+ He should accept some donations of course, but if he refused he should have his own reasons and I respect that. But I can give him a thank you  :-+ :-+  for this nice custom firmware. On the other hand, RD will also gain from this because they will sell more units  :-+
RD should realize that an open source firmware, or improve features according to customers feedback will make them sell alot of units all over the world, and increase their profit and name, instead of just increasing output Amps and change model numbers to release a new model. Most of the buyers of this type of electronics are mostly amateurs, or professionals ( wanting to disassemble and study), and most of us like customizations. I personally buy stuff that could be firmware customized.
It's the same has buying an oscilloscope, those models that are easily "hacked" are the ones that sell more like Rigol DZ1054z.
As an amateur I would like to continue doing my hobby in a budget.
That's my 2 cents

You fix the features, for free, I didn't have or like and it was enough. Of course, I would like to have the source files to learn more about this thing, but I can live with just the firmware that make me love even more this cheap device.
Regarding that fake feedback on RD page, I also saw this and other ones.

I think RD is not the manufacturer of these power supply modules, and I explain why:
Yesterday I asked them what is the model of the LCD because I want to buy a spare replacement and the answer I got was "common 2.4" screen" and  that they "did not know or had that information", that is a little strange right? Secret is the business success!  :-DD
Anyway, I managed to get this information by watching the video posted by RD, where in a video sequence it is possible to view the model number  :palm:

I leave here the reference for those who need it (also RD staff  :-DD):

Model: Z240IT010 v0.1 without touch screen
2.4 inch 240x320 SPI TFT LCD Serial Port
ILI9341
18 pin

Anyway, with a little time, it is always possible to solve conspiracy theories  :-DD

And I am by no means trying to lower the reputation of the RD, on the contrary, because they put a power supply on the market (manufacturers or not), with a keyboard, at an affordable price, and full of features (even more with this new custom firmware), suitable for most users.

I would like RD or other company to create an electronic dummy load, with keyboard, graphic display, data log, and also at a low price  :clap: :clap:

I like cheap and functional devices like the hated Fy6600. I bought one Fy6800 and replace the power supply with lithium batteries, a bms, some conectors, 7805 and 7812, 7912, capacitors, making this unit portable and without that power supply problem anymore. To bad there's no keyboard and interface firmware is a little non user friendly, for the price of 85 euros I have a functional device full of features that otherwise would cost me hundreds of euros, too much for amateur side  :-DD

What I found out, is that most of the devices created in china are not very user friendly, user interfaces are not well design and that could make a good product into a non loved one.

I wish you can add in charging mode user settable parameters Vlpt, Vpre, Ipre:
  • Vlpt = voltage threshold -> if U is below when entering charge mode then don't enable charge! (protection for deep over disharge lithium)
  • Vpre = voltage precharge -> if U is between Vlpt-Vpre then limit current to Ipre default can be 0.1C (protection for light over disharge lithium)
I thought about how to implement this, so that it would be convenient and at the same time not interfere with anyone.
Making settings through the settings menu will be very inconvenient.
It is better to make a separate menu, quick access, for example, called by the ENTER button.
Where can be implemented some timers, charging modes with presets, etc.
But here I need more ideas and algorithms, with a more detailed description.

I think you should keep the same logic on accessing menus instead of the ENTER button it's more logical to use SHIFT + Up arrow for example to implement the new separate menu and it will be easier to add a sticker above that button keeping the design, just like OPP above MEM button.

see the imagem I attach

Arrow up and down won't interfere with shift pressed while if I'm on layout 3 when ENTER is pressed it will pause graphic log and you'll have more work solving this

Arrow up and down will give you space for 2 more separate menus  :-+ I correct this, 4 more spaces, 2 with shift, and 2 arrows alone  :-+

It is not the modified firmware.
It is recovered source code from dump of stock firmware, optimized and some functions complete rewritten from scratch.
In my opinion, modified means some kind of binary patch.

Can I flash the latest over the stock firmware or do I need to jump through different versions (like some cisco switches, lol)
No need to flash different versions...
Just one recommendation: before flash to stock firmware it is better to reset settings to default (keep pressed '0' while power ON), and then flash to stock firmware.

My RD6012 works fine but I get such a heavy inrush current in the NVVV S-800-70 SMPS that the contacts of the rear power switch spot welds itself and won't switch off! This is on 125vac USA power. I had another toggle switch and tried that - 20A 125V rated and the same thing happened.

I unplug it to turn it off, then toggle the back switch a dozen times to get it to unstick, or take it apart. I have an open ticket with Banggoods and I obliged them with a video of the problem but they have gone silent for a week now (Chinese holidays are well over I believe).

Any other USA users of this SMPS experience this problem?

Hi all!

UniSoft, great firmware, I like it very much.
Can I request a couple of features?
1. CC/CV indicator doesn't look readable enough. Can you replace it with a green/red circle, like LED? And maybe draw it in a different place?
2. Would be great if points of actual voltage, current, and power numbers will be on the same line (even though there will be less of digits for current). This can be a separate menu item "2/3 digits for current"

Thank you!

PS: one more thing: It will be handy to have the feature: setup time to disconnect the load if the PSU goes to CC mode. Say, you build a device that normally consumes 0.5A. If it consumes 1A and above - then this is really something wrong with it. You can set 1A current limit and 200mS to disconnect. Smoke tests would be much more controllable. :)

I don't understand what exactly you want to get.
Can you take a screenshot and draw the sample?
As I said before, RAM of MCU is too small to implement shadow video buffer, so all drawings goes direct to LCD, without buffering.
So I need to know exactly all positions pixel by pixel (and all fonts have exact sizes).
If not fill some pixel(s), then will be artifacts from previous screen,
If to fill some area twice (for example: first fill the background and then draw on top) then will be terrible flickering...

Probably won't be too crazy to port OpenDPS to it. (https://github.com/kanflo/opendps) I don't have the time to do it currently though as I'm toying around with a uSupply style device

Also looks like it might have the same issue all the other DPS devices have where the voltage sags under high current draws. See here for more details (https://github.com/kanflo/opendps/issues/7)

You can calibrate both the display and the output voltage separately by entering the coefficients of the function y=a+bx.
I spent more than an hour, but now the readings have an accuracy of one in the last digit.

Its close but not 100%. Devices usually have large input capacitance and inrush current. Overcurrent protection delay can help to deal with it.

the hole between icons looks ugly...
That area, where you put the led, is a text area, there can be other strings which is much longer then temperature, so it is not acceptable.
It is more easy to use different background color.
 
Its close but not 100%. Devices usually have large input capacitance and inrush current. Overcurrent protection delay can help to deal with it.
OCP is not working instantly, in some conditions delay can be up to 1 sec.
Change setting "Upd.R" to slow, and you will get delay more than 200ms for sure

P.S. By the way you can write in russian forum (the link is in readme.txt), and discuss the ideas with other users.

Rather than simulate an LED for CC, what about changing the background text color behind the AMP's digit's?

I would prefer the "ON/OFF" button to turn red in an overcurrent condition. But this would require a modification. Adding a red led and sacrificing an output pin.
If that power signal output that was added before is used as an OC indicator, then I would be happy to mod and add a red LED :P

That's a great idea, now l want to do that too! Is there any free GPIOs left? UniSoft, can you do such firmware modification?

It would probably easier for uniSoft to add a menu option to select the function of the current GPIO pin assigned for the "power switch" (i.e switch between power switch & OC indicator) if another GPIO cant be easily accessed.

Hope, there is one more free pin, even though the wire has to be soldered directly to the MCU package. I'd prefer to keep both relay and red LED features.

PS: UniSoft, how about to align all measured digits in a column? Seems it looks more readable. See picture. I suggest to add a new menu item: 1mA/10mA resolution. Just to do such allignment.

Thats a good idea. I guess when you make the output and input (to turn both LEDs off) you will have to tell us the combination of resistors to use as both LEDs might be on at the same time when output is "tri-state" :P

The other option is you can use the single wire addressable RGB LED (WS2812B), but you will need to make sure that you can send the burst of pulses (uninterrupted).

Thanks for you work and listening to ideas :)

On a 3.3 V device the voltage wouldn’t be high enough to illuminate both LEDs significantly so they would appear dark.
Resistance is not critical: something in range 2KΩ ... 2.4KΩ

1. CC/CV indicator doesn't look readable enough. Can you replace it with a green/red circle, like LED?
And by the way, here is a small bug...
In stock firmware in CC mode background of icon becomes RED (while I'am changing foreground to RED),
so I will fix it next version

I guess if there is a slight illumination of both LEDs when off, I could add a diode in series with the lowest Vfd LED (and adjust the resistor). This would compensate if required :)

Hi all, I just found this thread and haven't read through all 400 posts, so forgive me if this has already been posted.

First, UniSoft - truly awesome work!
I can't help but read your replies with a russian villain voice in my head, like in a Bond movie.  ;D

In post #280 (https://www.eevblog.com/forum/testgear/ruideng-riden-rd6006-dc-power-supply/msg3211698/#msg3211698) you asked for a "good small embeddable power supply".
I've used these with good results: HLK-PMx (https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313&_nkw=hlk-pm01&_sacat=0&LH_TitleDesc=0&_osacat=0&_odkw=ac-dc+5v).
If it's just there to power some logic an a small relay I think it would be fine.
My 2 cents.

Do you need the CR1220 for the RTC to get the wifi to work? I can't get it to pair (RD6012)

No, that is independent. The battery is only for the RTC. You can run WiFi without that.

WiFi is sketchy. Haven't succeeded in making it work via iPhone, but via an old android tablet it worked. The WiFi (edit)setup method of operations(/edit) is rather non standard: it wants to connect to the "host" address (the mobile device + app) used at init time.
There are mods around for making the wifi feature more useful, like https://community.home-assistant.io/t/riden-rd6006-dc-power-supply-ha-support-wifi/163849 (https://community.home-assistant.io/t/riden-rd6006-dc-power-supply-ha-support-wifi/163849).
You can also look at the discussion here some time back: https://www.eevblog.com/forum/testgear/ruideng-riden-rd6006-dc-power-supply/225/ (https://www.eevblog.com/forum/testgear/ruideng-riden-rd6006-dc-power-supply/225/)

Ok good to know, thanks

The WiFi setup is rather non standard: it wants to connect to the "host" address (the mobile device + app) used at init time.

Sorry I should have been more clear. I can confirm that the ESP8266 is not broadcasting, so it is impossible for pc or phone to send the setup information to the device. Clearly my module is faulty

FYI this method is used in many devices to set up wifi. I wouldn't call it non standard at all
Title: Re: RuiDeng Riden RD6006 DC power supply
Post by: bateau020 on October 23, 2020, 08:21:04 pm
Sure, the method you mention (which is indeed the method used here AFAIK), is used to set up many devices indeed. I have also used it in my products. However:
1) this device, when non-configured, sets up a hidden SSID. So depending on the method you use, you might not be able to see it. It is to that SSID the mobile app connects to, to set your AP's SSID/pwd (and more). So far so good. The non standard part comes here:
2) I was referring to the method used once the init has been successfully done at least once, so after the configuration of the SSID by the mobile app. The fact that it wants to reconnect to the exact IP address that the device that did the configuration had at config time, is rather non standard I would say. To be explicit, the IP address shown at startup (once the setup is done), is NOT the Riden's IP address (that will be via DHCP), but the address it wants to connect to, the address of the device that configured it. You can imagine the potential problems with that. Many people report having to redo the setup from time to time, as can be expected.
BTW, My phrasing above was a bit condensed, with a bad choice of the word "setup", where I should have used "method of operations". I understand the confusion. Edited.

If the module is faulty however, it appears (I have not checked, but see the pages in this thread I referred to) the ESP8266 is a regular non-reprogrammed ESP8266 12-F, using the standard firmware many come with. And if your replacement doesn't work, the stock firmware can be found on those pages as well.

Dear Unisoft

"CC/CV indicator doesn't look readable enough"

I ask you:

My idea is : Could it be written in the firmware an extra function , that in CC mode there is an "H" level on an output (in CV mode "L" level) to control an external RED led on one of the CPU unused port , or the either pin on J2 connector ?

There is only one unused GPIO... not connected pin...
And I am already planing to install RED LED under ON/OFF button...
Actually I already mount an LED (it is easy, cut the track, and drill the hole), but still not decide where exactly to connect (it will depends on initial state of GPIO).
I am not at home now (working in another city), and don't have RD with me, maybe go back home after 2 weeks...
Then can continue my work on firmware...

Hi unisoft i really like your firmware, it made ruideng RD series a very good and usable power supply.
I tried the firmware of RD6006, RD6012 and RD6018 all beautiful and functional, I would be very happy if it was possible to insert the support to have these two additional functions  ;D ;D ;D :
- via a pin the remote on / off control of the power supply configurable as a pulse for switching on and off, as logic level 1 for on, or logic level 0 for on  8) .
   I could produce the wiring diagram with optocoupler to fit the pin input
- SCPI support even only for on / off and reading of main parameters 8) .
thanks greetings to all  :) :) :)

First I drilled a hole.
I did not have a thin drill, I took a 0.8mm drill.
(https://i.ibb.co/f93bm01/1.jpg) (https://ibb.co/f93bm01)
Cut the track.

soldered the red LED.
(https://i.ibb.co/ZHzhR13/4.jpg) (https://ibb.co/ZHzhR13)
inserted a wire (in Teflon insulation) soldered to the diode.
(https://i.ibb.co/P1T0vBj/5.jpg) (https://ibb.co/P1T0vBj)
connect to the mcu over resistor... on photo resistor 2K, but latter I replaced resistor to 470ohm.

As an alternative solution...
Illuminate the button from the side by installing the LED (some side emission bright LED) in the case.
For example:
(https://i.ibb.co/RTWNgFg/l1.jpg) (https://ibb.co/RTWNgFg) (https://i.ibb.co/c338SWw/l2.jpg) (https://ibb.co/c338SWw) (https://i.ibb.co/vjMcL7D/frame.jpg) (https://ibb.co/vjMcL7D)

Next version will have an option "External LED", to control that LED
- "OxP" - Red in case of Protection...
- "CC" - Red in CC mode
- "CC + OxP" - combine first 2 options (Protection - Red; CC - Yellow; CV - Green)
- "CV-G/CC-R" - CV - Green; CC - Red
- "CV-R/CC-G" - CV - Red; CC - Green
If anyone has any idea what else to add here, let me know.
(https://i.ibb.co/GC8YfHW/extled.png) (https://imgbb.com/)

As an alternative for CC/CV modes will be possible to set font color and background color...

New Quick Menu (activated by pressing button "Up")
This is the options for current session only (no store).
"Timer OUT Off" - Turn OFF the output after specified time...
"Timer Recycle" - Prevents Reset Timer...
After switching off the output (upon reaching the time or manually), the timer will be reset (unless option "Timer Recycle" is enabled).
The timer can be activated both before and after the output is turned on. Timing starts from the moment the output is turned on.
Thus, if you enable the output, wait more than 10 seconds, then activate the timer for 10 seconds,
then upon exiting the menu the output will be immediately disabled (since the time has already expired).
If anyone has any idea what else to add here, let me know.

Not everything that was intended has been implemented yet.

Hello UniSoft

Is it possible to program a option to use the "Batt Temp" for switching off the output, when a defined temperature reaches.
As you know, this function works only with the battery charging output (green socket).

Many people doesn´t use the battery function, they only monitor with the battery-temp-sensor the power switching supply (heatsink).
The idea is, when the heatsink (Mosfet from PSU) reaches a defined temperature, the ouput will switch off to protect the psu from heating damage.

Maybe you can also put both temperature values (system temp and batt temp) side by side, when this function enabled (to read both values at a glance).

I don´t think that is a big deal for you to change it in the source code.  :D


PS: Thanks for sharing your work with us.  :-+

this function called OTP (Over Temperature Protection), now it is implemented only for internal sensor and have a fixed value 80°C

Maybe you can also put both temperature values (system temp and batt temp) side by side, when this function enabled (to read both values at a glance).
If you mean in header, then there is a space for maximum 7 characters.
Actually it is enough to display the highest temperature from both sensors...

Hi UniSoft

Actually it is enough to display the highest temperature from both sensors...
Is this feature already programmed or will you implement it in the next FW? -> the highest temperature from both sensors will be displayed

It is also possible to put both values right at the bottom - but it´s only an idea, not necessary to put in a new FW.
(https://i.ibb.co/5T0whBd/T2.png) (https://imgbb.com/)

I will be happy, when you only implement a programable* OTP (with external temperature sensor), as I mentioned it the last post. 
*User can set a value between 40°C and 90C° or more  :-//

Is this feature already programmed or will you implement it in the next FW? -> the highest temperature from both sensors will be displayed
Will implement in next version... actually already done...
Header will show only internal temperature, current temperature (from ext sensor) can see in Layout 2,
or select option to display temperature in status bar.

This is really impressive work on this power supply, has anyone done any noise measurements on this or can point me to the right place?

Thanks in advance for the help and Happy Thanksgiving.

Best,

Soon!
New model RD6006P on the way!
Contains external ADC IC.
And as I understand this is a Switch mode/linear hybrid power supply.

Good 0.001V and 0.0001A.
It is just me or they implemented some features of Unisoft?

Yep... They copy some ideas from my firmware.

This looks very interesting!! Although I can't read it, the extra precision readout and the possibility of a "hybrid" SM/Linear is quite intriguing indeed  ::)

Hope to see what you find out, again thanks for all the effort you've put into this :-+

Best,
