RuiDeng Riden RD6006 DC power supply
« on: August 28, 2019, 06:32:51 am »
Ruideng, 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.

The Windows software for this unit is detected as a virus by 5 virusscanners (used Jotti's virusscanner page)
So the file was already removed when I tried to unzip it.

Does anyone have a version which is not recognized as a virus?

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.

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.

What parts came bundled with your package?
The whole housing? just the PSU appart?

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

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

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

I stated that, big mistake indeed, we can replace the cap to other color but why green  :-//

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.

Good quote from the manual:

The calibration fine-tuning function needs to be operated by a professional electronic person who has more than five and a half multimeters.

SDGs video:


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?

So I think the virus is on Banggoods link only. I used the google link provided by Glen and there was no issue: https://drive.google.com/open?id=17V-JWHvqMF-NuWSznEiJ4RKrnn_Pkt5v

Apparently his account is banned here, so he won't be posting.

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

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? :-//

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)

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.

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).

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 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:

Nice that the developer of these modules makes these kinds of video's to answer questions from the buying public.

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.

Probably won't be too crazy to port OpenDPS to it. 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

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 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.

Wonder if the firmware is going to get reverse engineered, would be nice to add some linear post-regulator and a proper current limiting stage, maybe voltage sensing connections.

See my post above, no sag noted. Just tried again with a bench meter and got the same results on CV or CC (but at a slightly lower voltage out). CC does bounce around a bit, regulation of that isn't great.
Funny I'm also working on usupply device  8)

As SDG noted, external sensing is probably possible to add in.
Post linear reg.. hm maybe possible but you'd really be screwing with the feedback loop at that point.

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.

He likes it.
There is no overshoot when turning on and hardly undershoot.
The switch mode noise he displays is not correct, see his sticky in the comments. He didn't use a 10x probe  :palm:
Noise is about 60mVp-p no load and about 100mVp-p at 6A he says.

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.

Better, use a 19v LT adapter.. or two or three identical LT adapter's in series for ~37v or ~54v (open them to make sure outputs are truly floating*, pre-load each with 200 to 500 ohm's @2W and put 6A diodes between them to protect from back-feed)

It's a nice power supply, but if your SSID has spaces, it won't connect.

With IOS13, new iphone and spaces in SSID, the app closes when you hit "Init or Distribuition".

There are two options, either they fix the firmware, or we need to wait for someone to hack this firmware! :)

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

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

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. Possibly my search skills late at night are lacking, but I could not find any documents describing the RD6006 protocol. 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.

Code: [Select]
// 0x00 - Model? (60062 on my RD6006)
// 0x01 - Serial Number MSB?
// 0x02 - Serial Number LSB

Since people are posting their cases for this PSU, here is my take on a case for 2 of these.

The AC/DC 48V PSU is external. I 3D-printed brackets to screw it to the bottom of my workbench.
[attachimg=6]
[attachimg=1]

Then I designed and printed a case with plenty of air vents, a cable inlet and one hole to screw it to the wall
[attachimg=2]
[attachimg=3]

The 2 PSUs fit perfectly.
[attachimg=4]
[attachimg=5]

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. Possibly my search skills late at night are lacking, but I could not find any documents describing the RD6006 protocol. 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.

Code: [Select]
// 0x00 - Model? (60062 on my RD6006)
// 0x01 - Serial Number MSB?
// 0x02 - Serial Number LSB
// 0x03 - Firmware (125 = 1.25)

// 0x33 - Hour
// 0x34 - Minute
// 0x35 - Second

Thanks! I didn't find this post until I had mostly figured this out myself, but good to find confirmation on most of what I did find.  Here's a few extras:

Code: [Select]
0x10 - Protection status (0 = good, 1 = OV, 2 = OC)
0x48 - Brightness (0-5)
0x50 - M0: V * 100
0x51 - M0: A * 1000
0x52 - M0: OVP V * 100
0x53 - M0: OCP A * 1000
0x54 - M1: V * 100
0x55 - M1: A * 1000
0x56 - M1: OVP V * 100
0x57 - M1: OCP A * 1000
[... repeat through M9]

However, I have not yet determined which register is used to load a memory group into active (it was 0x23 on DPS devices).

I have a Python program which has full support for RD UM / DPS series devices; I've just added initial support for the RD6006: https://github.com/rfinnie/rdserialtool

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.

 :-//

Chris




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!

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

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



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/

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?)

Hmmmm looks like something isn't isolated..

Output was turned off, and I inserted a USB cord, there was an arc to the negative post and this happened

Needles to say, the USB port is dead

Wow ... I've been wondering about this situation too when the 1st time I saw that USB port.

Curious if RuiDeng will cover that with their warranty ?

I'm guessing that the negative output and the USB ground are not common and so there was a potential between the two, I'll tear it down later and see what I can find

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

I think if you watch his subsequent video, it's not nearly that high. Some YouTubers also measure much less.

RD6006 has a large output voltage ripple when switching loads 5A, setting current limits 6A.
Oscillograms of the transient process with a periodic connection of a resistance of 5 ohms with an output voltage of 25V.

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.

RuiDeng actually had an active official representative here, too bad got banned as couldn't refrain not to keep spamming their product here again n again in this forum.

I have the same problem. I can't find a version that even installs. Not too bothered though as I doubt I will ever need to control my PSUs from a computer. Graphing of some values would be nice though.

It looks like the module itself isn't a huge source of noise, if fed with a linear supply it's actually pretty good

Enjoyed the video (duly subscribed as well)
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?

I am quite tempted to give it a shot on mine once I have the USB interface repaired. I'll do a write up once I do :)

Can you quote some specific loads and p-p ripple voltages please?
In the other thread 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?

@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

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.

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

That seems entirely plausible to me

Okay, I am a bit dumb - can someone explain to me what the hell is going on here.

61v of potential between my scopes ground and the (output off) ground on this supply.

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.


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.

60v seems like more than just a little to me.

I have attached a pic of the damage it did to the clip on my scope lead (scope is okay thankfully)

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?

I thought of a slightly easier way to test it. I installed a little 12v 3a meanwell SMPS I have here in it, and surprise surprise - it doesnt exhibit the same behavior. So clearly this crappy little 60v SMPS is at fault.

Further development. It's the screws in the mounting on the underside of the SMPS, when they are fully tightened it seems to short...  :wtf: :wtf:

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.

It was just the screw under the positive output side of the SMPS, it was obviously pinching something so for now I have just completely omitted that screw. I'll keep an eye on it and see if it starts behaving.  :palm:

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.

I am just waiting for the replacement parts and the wireless adapter to show up so I can have a poke round on that side

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

No one have found strange problems/behaviours with this psu?
I was in doubt between this and a korad... but i think that i've found my new bench psu  8) 8) paired with a good linear backend i think that can do a really good job.

Thank you for the tests!

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...

Hi,

did you find the cause of the explosion ?
It was the screw length ?
I have one of those power supplies and, as you noticed, the screws are lite bit longer as .
I go to buy some washers in order to avoid such CC.

it was 100% caused by the screw hitting the leg of the main output cap in the 60v PSU :)

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.

Good question. I just finish this, and now I'm testing it in different scenarios.

For now please note the following things:
  • The node-red-contrib-modbus as the feature 'auto-reconnect' in case of lost connection (timeout user-defined).
  • In case of disconnection, the charge process is still working on RD6006:  it will terminate for   (OVP, OCP, OTP, Iout<10 mA) only. Of course, the user is losing the log.

Hello..

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



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

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.



specifications:
Voltage: DC 12V ± 5%
Load type: constant current
Load voltage: 0.5-60V
Load current: 0-10A
Max power: 150W
Voltage measurement accuracy: ± (0.1% + 0.05% FS)
Current measurement accuracy: ± (0.2% + 0.1% FS)
Constant current accuracy: Current reading accuracy + 1d
Noise: 25dD (A)

Here are two videos of me about the DIY kit RD6006

Part 1: assembly and first test
https://youtu.be/VnlaPLzZtF0

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

Part 3: The third part about the RD6006 power supply is about Rippel and Noise
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.

3.pic


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



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.

Greetings Rolf

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.
My firmware on the supply is V1.25.

I also managed to sniff this URL from the windows app

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.


Thanks BlackFX for the link.

Just to add an useful piece of information, I just updated from firmware 1.25 to 1.28. The release notes showed in the software are:

Code: [Select]
2020.01.13 V1.28
1. Optimize the anti-interference ability of battery voltage measurement
2. Optimize the relay to be forced off during standby
3. Optimize the shortcut to call out the data and enter the setting data to change the stored data group indication
4. Optimize the problem that the product will freeze for a long time during long-term communication

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.

RD6006 controller and control lines


RD6006 parts


RD6006 power supply board

On the power supply board I have removed all parts that are not needed.

Circuit diagram


Heat sink and test board






I'm also planning to switch the transformer voltage from 15VAC to 30VAC to minimize power dissipation at the power transistor.

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




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).



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.



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.

Addendum to the last circuit diagram: Resistor R9 in the monostable
Flip-flop has a value of 680K Ohm and resistor R5 goes to GND.

Now follows the installation into the housing. The additional electronics (on the
plug-in board) is placed to the left of the board with the heat sink.

All components wzB the power transistor with heat sink,
Rectifier diodes and power supply unit are positioned so that they can be
fans can be well cooled without obstacles.

The temperature sensor for fan control is mounted on the heat sink
fixed. The fan starts with the smallest fan stage at 38 C degrees at the
heat sink.



The board with the heat sink is from a Vellemann
Power supply kit with a uA723 which I do not use.

Hello friends..

Little progress report. I've already soldered part of the circuit board.
For the power connections I paid attention to short connections and
the relay (blue component) for switching the transformer windings very
soldered far forward near the connections. The protective conductor
(green/yellow line) I have not forgotten. This one is also called
connected to the housing.

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).

Pic1


Pic2


Pic3


The question remains, if I can optimize this in the circuit a bit
?

For help and suggestions I am very receptive ;)

Now I have increased the capacitor C1 at the output from 100uF to 470uF.
The rib dropped from 40mVpp to maximum 20mVpp (3A load).
Without load at the output the ripple is 7mVpp high.

Hello..

The installation is now almost complete. I just have to
Enlarge the housing opening for the 80s fan on the back.
I have the control cables from the RD6006 controller
Ribbon cable connected to the board. This makes everything easier
disassemble.



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


Max load 32V/3.2A



The Jerry Walker conversion only applies to the power supply. The
Control takes place as in the original power supply with the switching regulator on the
RD6006 controller board. You can do that in the video at the 200mVpp
Detect switching impulses.

Hello..

I have optimized the power supply circuit a little. To the
Regulate the output voltage of the power supply to approximately 0 volts
1K resistance between emitter and base of Q4 against a diode
exchanged. I have adjusted R13 from 100 Ohm to 82 Ohm (1st picture). V4
is the control voltage from the RD6006 controller (0-1.42 volts).

Simulation circuit


The residual ripple (ripple and noise) at the power supply output is included
a load of 3.3 amps under 6mVpp or 1.85VRMS (Fig. 2 + 3). I
have the power supply with different output voltages and loads
tested and can no longer detect vibrations. The
Output voltage remains very stable up to 32V and 3.3A.

no Load


Load 10V/3.3A


The next step is temperature measurements in the housing and the complete circuit.

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.

But... The question then arises whether the ripple and noise will remain below 5mVpp.
Therefore I would have to change the firmware in the RD6006 controller.  :phew:

It has a zero calibration and it is possible to adjust the offset to plus from the set value. At what maximum level I do not know.

Hello..

I still had a little difference between the one displayed
Voltage values on the display and the voltage at the power supply output.
With the help of the software "Riden Power Supply Software" I was able to
Calibrate the power supply or adjust the current and voltage values.

Info: The code for calibrate is 168168



Since I don't quite get the lower voltage value with the calibration function
I have another one in my power supply circuit
High-resistance resistor R16 from the negated OPV input to the negative
Operating voltage connected.

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.

Hallo Arthur

That's a good idea  :-+

But.. Is the switch suitable for 230V~ ? If not, there is a risk to life !!

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.

There are many devices on my work table that I have to switch on by hand.

Most have the power button on the back. Too stupid  |O

Hello..

I have built a second power supply circuit with an LM317HV and power transistor as a current amplifier. I was interested in the load behavior and the ripple of the circuit.

What surprised me compared to the old circuit is the small ripple even under high load. The load pulse is also much smaller. In the old circuit I had up to 500mV peaks.

Circuit


Ripple & Noise no load


Ripple & Noise  load 10V/3100mA


Load switch on 3100mA


Load switch off

PSU seems to be a cloned meanwell, PCB marking is S-350W-R4, the closest I found is a previous revision, most values match but there are some differences, particularly this burnt resistor doesn't show on it

The burnt resistor is marked SR1

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


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).

Vin no load (measured at C2)


Vin 3A Load (measured at C2)


Vout 3A Load (measured on C6)

Hello..

I have also examined the switch-on and switch-off behavior on the power supply (Power switch).
The result is very well. An overshoot is not noticeable.

Power On No Load


Power On 3A Load


Power Off 3A Load



It is recommended to add a resistor of 2.2KOhm to the power supply output,
so that the voltage at the output can discharge after switching off. At a maximum
Output voltage of 32V, for example, the resistor should have a power of at least 0.5Watt.

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.



Link:
https://de.elv.com/elv-prozessor-netzteil-pps-5330-komplettbausatz-075572

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.

Re: RuiDeng Riden RD6006 and RD6012 DC power supplies

Hi,

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

This ad present the two datasheets : http://www.aliexpress.com/item/4001053200176.html

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.



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.

ELV PPS5330 Origin


PPS5330 electrinics


PPS5330 with RD6006 control


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.

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.

PPS 5330 Front case


Unfortunately, when unpacking, I found that the front frame
something is bent. However, I think I have the front frame again
can set up and then the assembly works without further problems.

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


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


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.

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
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:


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.



Other Styles:





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

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.

This is great! Really impressive work! This custom firmware looks great. I'll definitely be installing it later on my RD6006. 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!

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!
I can't post sources... it contains private encryption keys to encrypt firmware,
I don't think that developers will be happy to see it in public...

Done

Excellent work.

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 understand about not opensourcing this project. Still a really cool project and thanks for implementing the feature I asked for. One other thing I heard some people mention in the review of the original product is that the color coding doesn't really mean anything, so it would be cool if you could fix that!   ;D :-+ ;D

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).


If anyone have any interesting ideas about layouts let me know.
Better if you will make a sample image (for example in Paint.NET)

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/

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

I agree the smaller font does not help with readability, the screen is so small already so a large font works best, at least for me.

I agree, the only thing I can think of that this is missing now is wifi!  :-+

As for the smaller text, it's really down to personal preference. I like the larger text because it's easier to see, but the smaller text diffidently is nicer on the eyes. It really doesn't hurt to have as an option either way  ;D

The Wifi connection doesn't seem to be working for me. Following the steps from RDTech, once the app connects to the RD6006, the RD6006 seem to skip connecting to the network and continues to the main screen. Is this a bug or am I doing something wrong?

Not the type of PSU I am interested in, however, I just got an email about the RD6012 which has a 12A current limit.  It is on sale for $53 at Banggood, thought I would share it with the community in case you are in the market for this type of device. 

I have nothing to do with the commerce site or the product.

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...

USB interface is complete isolated!!! This IC is used (p122U31):

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.
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 :)

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....

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,
Alex

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.

Re: RuiDeng Riden RD6006 and RD6012 DC power supplies
« Reply #233 on: July 03, 2020, 09:35:12 pm »
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 and RD6012 for embedded design / hobbyist use.

Here are the specs I care about. According to the datasheet:
  • 👍🏼output current
  • 👍🏼output power
  • 👎🏼output current set & measure resolution
  • 👎🏼output voltage ripple

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.

Hi Unisoft, Hi everybody,

Is it possible to update this PSU device from my linux laptop or must I find a windows-PC in order to use the propriary Ruiden software for windows ?
I can't use the android software because my phone is under Ubuntu-touch !

I understand that common protocol uses a standard input/output way. But does it work for update software ?

Have a nice day !

Did you mean updating the firmware from Linux? Quick search on github for RD6006 yielded Python script for updating firmware: https://github.com/tjko/riden-flashtool

There seems to be command line utility (Perl) as well: https://github.com/atu-guda/rd6006_op
And Python library for controlling these easily from Python scripts: https://github.com/Baldanos/rd6006

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.

That "Power" button doesn't seem to really do anything but turn off LCD (and turn off output if it was on) ?

I recall unit consuming still about 1W even if "off"...

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).

Here is my BETA version for RD6012...
Bug reports are welcome.

--- RD60121_V1.31.1.bin ---

* Initial BETA version
* Optimized, get rid of HAL Libraries... switched to LL
+ The menu was complete remade.
+ |SHIFT| + |Left/Right| — switches the current layout (without save in settings)
  (if need to set layout after power on, then can do it over menu settings, same as before).
+ For 'layout 1', can be enabled/disabled items.
+ Added OPP (Over Power Protection).
+ |SHIFT| + |MEM| — used to setup OPP
+ OVP, OCP, OPP — now can be disabled by setting it to 0 (0 is equal to maximum)
+ 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.
+ Added Setting for current cutoff in battery charger mode.
+ Added Setting for batt temp. cutoff in battery charger mode.
+ Added Battery Charger Layout
+ Added Setting to skip keypad lock when connect with software.
+ |MEM| + |.| — now used to reset Wh, Ah
+ Option "Digits Style", can select style for large digits (32x64, 12x24, 7-Seg)
+ Decreased minimum battery voltage from 900mV to 300mV
+ Option "SkipExitIVSet" (prevents exit from edit mode for V-SET and I-SET when press ON/OFF button).
+ Option "Power LED" (Setup the behavior of the power button LED in power off mode (Default-pulsating, 0%-off, etc...).
  (in modes 0% and 100% power consumption will be less (cause no need software generate PWM and can switch MCU in to the sleep mode)

Ups, really... And nobody reports.
Initially, I did 0-25-50-75-100 there, I forgot to change number of options.
Thanks, I'll fix it latter.

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.

It is possible to have a case fan controlled by the external temperature probe?

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.

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!!!!!

Very pleasant for custom fw

I would propose to add more safety for battery charger mode.
Especially pre-charging could be improved quite easy by adding,
  • Vpre
  • Vlpt
  • additional charge complete timeout may consider as well



Nice 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 !

F.

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

I am a little adjust the PDF, now it contains all registers.

Hello,
thanks for sharing your work.
There seems to be an error with the attachment, it is not a PDF file but the WIFI dump instead.
Is it possible to get the PDF with the Modbus registers list?

Thank you.

I tried to make power switch...
On taobao found this remote switch


Inside view...


Remove radio receiver, and unknown IC (RFE261DK) have no idea what is this, probably some MCU.
Add optocoupler...


Add option in firmware... (will be in the next release)


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.


Also take 5V from this switch...
cut the track and put diodes


Can fit in original case
use double side sticker


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!  :-+
https://youtu.be/3djuP3JJplg

Now waiting for another relay module, and will use another 12V small power supply + 5V converter

+ Added option "Power State" (Power On, Power Off, LastState). Sets the state after power on (without a battery, LastState will not remember the last state).
+ Added option "Power Switch" to turn On/Off the primary PSU. (5V standby power supply required). (Note: Adds a 3 second power-on delay).
  The control output is routed to the PA14 port (pin 4 of the J2 connector). High level - turn on, floating or low level - turn off.
  Note: the maximum load on the port is 20mA !!! (it is better to use an optocoupler).
+ Added option "AutoPowerOff" to automatically turn off after a specified time if the output is disabled.
+ Added option Home:"Status Info" allows you to choose which parameter to display in the status bar (if you need something else, let me know).
+ Added option Home:"Mem Hint" If enabled, then pressing any number key will display a hint with the current settings in the corresponding memory cell for 1 sec,
   a second click during this time will apply these settings.
+ added new parameter "7-Seg v2" to option "Digits Style", where "input", "vset", etc. will also be 7-segment.
+ Added display of the system temperature to the caption.
+ Minor improvements
