Compared to RD6006, RD6006P hardware changes a lot though the look same from the front panel,
so RD6006 cannot just be updated to RD6006P just by updating the firmware.

Thread about RD6006, RD6012, RD6018 is here...

I drew a schematic of RD6006P... (Draft)
I drew it without removing the components from the PCB, so ~~there may be~~ for sure there are errors.
If you see anything, let me know, I can double-check certain parts of the circuit, until I assembled the power supply.

Got my RD6006P and it looks good so far. It came with V1.38 firmware on it and I miss some of the UniSoft "extras". Also have a RD6018 with the 800 Watt AC power brick and I got the RD600P without an AC adapter, so I use the RD6018 to drive the RD6006P.

The attachments show similar tests done on both power supplies: the reaction time from a short circuit until CC mode cuts in. The horizontal scale is the same: 50 microseconds. The "6P" has similar inrush (due to the short circuit) and settles near 0 Amps before jumping to the CC value of 1 Amp, all within 100 microseconds. The "18" takes around 270 microseconds to settle at the CC value of 6 Amps. The current is measured with a Fluke 80i-110s and shows the "18" peaking at 110 Amps while the "6P" peaks at 34 Amps.

Also did some measurements with OCP and the "18" and "6P" seems to be the same: OCP is done in software and is much slower tripping than CC mode reaction time.

Finally I assembled my RD6006P...

standby power 5V

Added 5V TVS...
I made a serious mistake and applied 12V instead of 5V to the standby power, so this TVS died (short circuit) and saved everything else.

And here you can see how I connected a custom LED (red LED under the ON/OFF button).
And also a power switch control signal.

@UniSoft

This looks very promising! Any measurements on load transients (voltage excursions upon applying a positive and negative load step)?
I'm curious how the linear end stage handles that.

There is a driver you may need to download and install if you're on windows 10 standby, I'll see which one it is.
OK I just looked this is the one that worked for me to get USB port working.
CH341SER
http://www.wch-ic.com/downloads/CH341SER_EXE.html

In my case my laptop connected no problem but I needed this serial to usb driver installed on the desktop.

Bought a RD6006P and was unable to connect to it via USB. Windows 10 version 21H1 running on x64.
Thank you AaronR (in the main RD6006 thread), installing the driver worked for me. I now see that the driver has loaded for my USB serial device. Hey people, make sure to select the new COM port that gets added. I wish Ruideng would make a note of this driver in their docs so I didn't waste time

EDIT:

I installed the latest UniSoft firmware (1.38.1a). Looks good so far. I really like that I can read the input voltage now (it is larger) and it has an additional digit. Thank you UniSoft for your work!

UniSoft posts his firmwares in the main RD6006P thread. Here is the latest (the 60065 is for the RD6006P). Click on the link to go to his post where the firmware files are attached:

Three in total can make a lot of noise.

Fan in the back of the case that is sold for the unit is normally off until things get fairly warm, then it switches to low speed, then if the unit gets very hot it switches to high speed. The only way I can get it to high speed is to run it at full power 60V, 6A into my DC load which has a loud fan, and the RD is not very loud in comparison. Of course everything is easy to get to in the case so you can modify it however you like or use a different case / power supply / fan entirely.

Would you happen to have any information on how the RD6006P differs from the plain old RD6006 when reading and writing via modbus? Ideally I'm looking for a reference like this ( https://github.com/msillano/RD6006-Super-power-supply/blob/master/RD6006_prtotocol_en.pdf ) which is for the plain old RD6006, but for the RD6006P.

My unit came shipped with V1.39 Firmware (v1.12 bootloader).
Everything is fine after flashing it back to stock v1.39.

I think they use some new LCD display...
This also explains why they recently released new firmware for all models, and delete old version.
I will check, and fix it in next release.

Great stuff. I will take a look through.
I did a review a while back, but I've not yet found any need for the additional accuracy, though given the price difference it's a no brainer to go for the precision model.

Hey, I really like your work, how well does it run with a linear power supply? I have some old audio amp parts, 55V 250VA transformer, 24000uF worth of caps and 25A rectifier. Was thinking about putting them together with the RD6006, but now I learned there is the P model. Costs 30 dollars more though. Is it really worth it?

Cliff Matthews · « **Reply #23 on:** September 06, 2021, 05:10:09 pm »

@Extra - Transfo's can't go above ~46 volts AC so rectified, DC input is ~5 volts under 70v rating of input capacitors.

My only and biggest complaint about the original RD6006 and RD6012 units, was the huge amount of noise and ripple they would put out. I measured more than 500mV peak to peak.

The screenshots for the RD6006P look great !

Now, if you guys will release a RD6012P unit, I will upgrade !!!

Does anybody know if a RD6012P/RD6018P is planned ?

Now it should cost $ 129 on Ali to Germany. This is too expensive.

I already have 4 models (6006, 6012, 6018, 6006P),
three of them are completely idle and just take up space.
I don’t want to invest in buying another one.
It is also time consuming.

Hello,
I have bought an RD-6006P, that I have just received today.
It is really a great PSU.
But 2 problems: one is the breathing led when it is shutted down.
And the other is a big one: it has overshooting problem

$:-\$

FW version is 1.40, so coming already with latest version.

Is someone has checked this ?
Is my unit has any problem ?
Maybe my simple setup to check this is not good ?
I have also a DPS5005 which has not this problem at all.

I have send a message to them on aliexpress with same photos (RD Official Store).

Here are the screen from my new DSO:

Hello,
So after my post, I have found and install your custom firmware, and I find it great, so thank you!

I have read all the big "RD60xx Custom Firmware Reference.pdf" and have tried many settings.

But I have the same overshooting problem with this one too, like the one I have posted before.
After some searching, my thought is that it is probablly because the output is activated too fast.
Do you think you could add a menu for slowing down the rise of ouput with a timing setting ?

I have tried also the using of the green port with the GreenOutput option: it seems to be better, but randomly (I think the relay slows a little down the rise of the ouput).

Also: same overshoot behavior after a releasing a short of the red/black bananas.

Thank you !

Edit: I have posted the video I have made for their support on Youtube:

Edit2: Here is my 3 years-old DPS5005 in comparison (I have sent to the RD support).
It is a lot slower, softer start, have more noise, but not a single overshoot.
And I can not notice the slow start when I use it

That is a very bad news

I have checked your schematics, it's the U8 part of the power part I think ?
And the main firmware is in the U8 flash memory of the control part ?

So I have to wait reply from RD...

Also, maybe you could check if you have overshooting on your model too ?

It will be great to know that, I could then compare with mine (if there is a hardware problem on mine $:-\$ )

Thank you for your answer.
I was not thinking about the boot logo...

Also, I have had an answer from RD, they told that it is a normal beahviour:
"Four-bit resolution digital power supply, PWM DA is used in the design, and the reference is added with RC buffer and then given to the comparison circuit, so that the voltage will not overshoot. The P series power supply has a linear adjustment part. In order to increase the response speed, this part of the circuit is not added in the design, so there will be a small overshoot.
so it is normal , not a problem"

So the "small" overshoot is about +0.40V at 1.5V (1.90V) and about 0.30V in average in most of the rest of the value

I reply them...

I don't know if there will be a solution for that.
So I do not recommand the "P" series at all if some of you plan to do low voltage electronics with it (so the precision and the noise is not usefull at all in these models).

Also, I have tried to follow the leads for the output, to find if I could solve this problem by adding a capacitor or something else anywhere, but it is really complex for me $:-\$
And adding big capacitor on the output does not change the overshoot...

Edit1: I have put a capacitor of 22nF, then 470nF in parallel of C9 on the CT pin of U2(TL594): the sawtooth is a lot slower, but nothing changes in the output form $:-\$
(with 470nF the frequency is about 1kHz)

Edit2: News from RD Support after my last message to them, they have reproduced the problem, and they told me that a fix could be done (hardware+software). Wating for them

Very great job from them !

And I'm super happy because I have contributed for the improvement of this really great little power supply

Now, I have to wait your firmware

First shoot is with the capacitor mod they told me to do with your fw 1.40 (same with the original one), and the second with the new 1.41 firmware I was waiting for

(voltage set at 1.500V)

Hi!

Got RD6012P, the RD6006P's more powerful version.
Today started using it as usual, but found that output voltage could not be regulated. It is aporrox. Vin-1.2V. Vin is 20V, so the output is between 18 and 19V. Unit is on CC mode, although no load is connected.

The unit is like new, never used with loads higher than 5A. Seems that some transistor is shorted. How to find one?

Thanks
Alex

update:
It was all my fault. I have desoldered LED on the back of the unit, thinking it was just for indication. It was not! Soldered it back and the unit is working flawlessly. D'oh

I picked up and assembled an RD6006P kit. It came with an extra surface-mount component of some kind in a bag that I have no idea what is for. It wasn't mentioned at all in the assembly video on Riden's YouTube page, but it's in its own bag so I figure the inclusion isn't a mistake. Anyone have any idea what it's for?

The photo on page 42 shows the inside of the device. On my device, the Q position (on this photo p.42) is empty (as on the photo). I leave this fuse holder empty and my device works.
I don't understand the comments about "less than 10A" for this fuse when the RD6012P is a power supply that goes up to 12A.

It seems that there is another fuse in position P. This additional fuse is perhaps a replacement for the fuse in position P.

I don't know...

Have a nice day !

Thanks! Hadn't even considered that it might be a fuse. Never seen a SMD fuses before...makes perfect sense in retrospect!
