Just opened this thread for the first time today. I've read a few hundred posts and... amazing stuff.

What UniSoft has done, and continues to do, is top notch. 

Deep respect for this kind of work. Well done, UniSoft. 


PS: The biggest contributor for his RD6024 should be RuiDeng themselves. They should send him a couple units for what he has done in increasing their sales!

Is it possible to make RED led mod with RK6006 (like it can be done on RD series) when overcurrent protection kicks in?

To answer the question, need a schematic.

Update...
There is no space to mount Red LED...

Hi there,

Am I the only one having a boot problem (hangs on a blank screen) with the latest UniSoft firmware (RD60062_V1.41.1k) ?
I managed to get my RD6006 to start by holding the "ON/OFF" button at startup, but it gets stuck again on the next power cycle :-/
Resetting to default parameters ("0" + Power On) did not help.
My screen is a ST7789.
Everything works fine with the previous version (RD60062_V1.38.1h).
Very nice job UniSoft by the way ! Thank you !

Hello, i've seen a custom firmware can be installed? What kind of feature/benefits does it add?
Is it possible to read modbus from 6006P from stock firmware?

Thanks

You could start reading much earlier dated posts. Yes, this takes time, so start about here https://www.eevblog.com/forum/testgear/ruideng-riden-rd6006-dc-power-supply/msg3104528/#msg3104528
Manual here (click upper right DL icon). Compare with stock FW and see changes.

I see,
what about the RS485 Registers?
i've seen some python scripts on github but i've also seen a comment stating that the protocol recently changed and might not work anymore. Is it a plain RS485?

Hi, i just tried Unisoft fw for the first time on my 6006. When i tried the latest version i got a white screen after restart. Doing a master reset fixed it. But after powering the device off then on made me get the white screen again. It was unusable. Then i tried the previous version. I liked the features but something was odd... the voltage refresh time was slow. And i also was getting some spikes on the voltage and at every few seconds there was a small current leak when turning the output on with no load attached. Returned to stock firmware and everything back to normal... is it just me?

Hey, thanks for this cool project.

There is the separate battery charging output. Maybe it would be useful if the memory banks switch to a battery labeled view and predefined values. Like M1 => NiMh, M2 => LiPo, M3 => M4 => LiFePo,..
Back to the regular output, the memory banks get restored to the user values.
Or maybe like a wizard driven menu: Type of Battery --> number of cells in row/nominal voltage --> number of cells in parallel --> capacity for each cell --> charging rate in C

Some improvements possible:

[new] CutOff Temp Delta: maybe it is useful, if you can define a delta above the room temperature. otherwise you have to adopt this constantly or set this high enough.

Can anyone comment on accuracy of sub-10mA current readings on a rd6018? I'm almost always running at 14.4v for car audio amp repairs etc, noticed my standby current on an amp was 0.000A (amp off but power connected). Expected 5-15mA..

I have confirmed a 1k resistor gives the expected .014A (@14.4v), but a 10k registers no reading. Using a dc electronic load, it does appear that the cutoff is ~10mA on the supply for displaying current draw.

I realize the spec from the RD manufacturer is only to 10mA, but the custom firmware allows visibility down to single mA.

Does this just mean nothing below 10mA will register on the supply despite being able to see single mA readings?

Bummer if so, wanted to make this my go-to supply for everything but high current load testing. Used a TP3005T prior to this..

Thanks

[bnae38]

Sorry if I'm not understanding.

Guess my point is, I can see ~.014A at 14.4v with a 1k resistor on the output. I can add a 10k to this and then get ~.016A.

So the rd6018 can see a difference in this small step in current with the custom code. However, it wont register anything below 10mA current draw.

I'm struggling to see how this could be a hardware limitation if it can resolve that difference. 

[Doman]

RD6018 has current resolution of 0.01A. So I think that currents smaller that that are simply not registered.
RD6006 has 0.001A resolution, RD6006P/RD6012P(in 6A mode) has 0.0001A. So RD6018 is designated for bigger currents and has lower resolution.


Anyway. I just registered here to say:
Thank You very much for this great piece of work UniSoft!

Understood, however Unisoft code allows 1ma visibility.

I am unsure how, clever averaging perhaps?

My question remains though, if the supply can spot a difference between .014 and .016A, why can't it display anything below 10mA?

[bnae38]

Unisoft, if it is averaging to get to 1ma resolution, could the same be done for currents under 10mA?

I don't mean to nitpick, you have clearly gone above and beyond on this multi-year endeavor. We all owe you a ton of gratitude!

Hi Unisoft,

Do you think this is possible? Just weighing my options, considering going to a rd6012p instead (even though no custom firmware).

Thanks!

A bit off topic - I bought RK6006, but when it arrived, was unpleasantly surprised by it's screen size (yes, that's my fault, I had to read specs better before purchasing). But since these devices are quite similar, were there any attempts to upgrade screen to larger one?

[smbaker]

Have folks started to experience encoder failures? I bought an RD6006 module about 3 - 3.5 years ago, and have been happily using it until today when the encoder suddenly became flaky. Sometimes it'll run backwards. Sometimes it'll skip many steps forward. I don't dare turn the encoder while the output is on, as I've seen it jump forward a half-dozen steps. For fifty bucks, I'll probably just replace the whole thing, but I'll also tear down the old one and try to fix it. Technically the problem may not even be the encoder itself, but could be noise in the associated logic.

Just curious if other folks have experienced the same,

Scott

RE:changing screen

I have attached a larger screen to a broken one for shits and giggles but it requires making changes to the source code which is not public.
 i was able to make it work by reverse engineering the factory firmware and making the required patches to one version of the firmware as i already have that framework in place as part of my efforts to produce a open bootloader.
it did however spur my to instead flash the wifi with ESPhome firmware that allows me to monitor better via remote screen and the device display shows other data.

Regarding the screen.
It not always requires code modification, if resolution and controller are the same.
I have in such way replaced 3.5' screen in Yamaha keyboard with larger one. It had exactly the same resolution and type of controller used, just it was physically large - 3.5 vs 5.5.

So I meant something like that - physically larger, to see the fine details better.

wow.. that was quick, I were looking for a software update for graph auto-scaling on my RD6006 1.28 , and suddenly I am running some custom firmware RD60062_V1.41.1k.  (I thought that was official updates.)
- nice - I guess.

Is there a changelog? - are there changes on how it communicates with a PC/python?

[wildekek]

I just updated my ESPHome/Home Assistant integration for the RDTech power supplies with new model support:
RD6006: ✅ Supported and tested. Just download the latest release and off you go.
RD6018: ✅ Supported and tested. Download the latest release candidate.
RD6006P:❓ Needs testing: check out the latest release candidate
RD6012: ❓ Needs testing: check out the latest release candidate
RD6024: 🛑 Not properly supported, as there is no Unisoft firmware yet.

See a little up: https://www.eevblog.com/forum/testgear/ruideng-riden-rd6006-dc-power-supply/msg4971583/#msg4971583

No real changelog. Riden also has updated its software since the start of the custom firmware, but overall the custom software is much better.

The PC/Python communication does not change. Wildekek (see just above) has made custom firmware for the WiFi module that make it esphome compatible.

I've been having an issue lately with the RD6006:

- When charging a battery (via the battery terminal), if I set the current to anything above 200mA, the power supply completely switches off.
- When I then wait for a minute, I can then power it up again by using the power button.

- Temperature of the system is about 40 degrees
- Input voltage (PSU) seems stable around 64v
- This does not seem to be an issue when using the normal (Red) output

Any idea what can cause this? I'm running Unisoft v1.41.1k

[bnae38]

Guess I scared off Unisoft with my neverending questions lol.

Sorry fellas.

Hi Unisoft,

Could you please share how you wired the capacitor bank?
