A video of such detail and professionalism can never be too long. Thank you.

There are quite a few video reviews of this PSU. However, yours was, by far, the most through and informative. Please do not be worried about such long videos. They are much appreciated.

Nice review, thanks, much more detailed and informative than the other reviews I've seen on this power supply module. The short circuit peak current is always a bit of a concern if you are probing around in a circuit and accidentally shorts something it could easily cause permanent damage to the circuit even if you think the current is limited to e.g. 100mA. I think the peak current is probably a lot higher than 2.5A, but that's the max value you'll get with a 4 ohm resistor and 10V output. It could be interesting to see the same measurement with a smaller value shunt maybe 50-100mOhm or something. I did a similar measurement on a linear power supply, reading ~14A peak from just 330uF on the output, although it only lasted something like 500 uS.

Thanks! I purchased the Gopher supply after your initial review and soon after another one for serial/parallel connectivity. I use them much more than my 3x more expensive device as I hate fan noises during the evening.

Best firmware for 6000 series is on EEVblog. Google *UniSoft RuiDeng Riden RD6006 DC power supply* for forum. Below is the Change log. You can always return to stock firmware at anytime. In case of any problems while update, keep pressed [ENTER] while power on device, to run device in BOOT mode. RD60062_V1.32.x.bin - my custom firmware. (where x - is the build number (sub-version)) RD60062_V1.32.bin - original (stock) firmware. If you want to return to stock firmware, recommend to set default setting To do this: keep pressed button [0] while power on device. --------- --- RD60062_V1.28.1.bin --- * Initial version * Optimized, get rid of HAL Libraries... switched to LL --- RD60062_V1.28.2.bin --- + The menu was complete remade, now I can easy add new items. + [SHIFT] + [Left/Right] - switches the current layout (without save in settings) (if need to set layout after power on, then can do it over settings menu, 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 + 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. --- RD60062_V1.28.3.bin --- + 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 --- RD60062_V1.32.1.bin --- * Updated to version V1.32 * Bug fixes --- RD60062_V1.32.2.bin --- * Bug fixes + Option "Digits Style", can select style for large digits (32x64, 12x24, 7-Seg) + Decreased minimum battery voltage from 900mV to 300mV --- RD60062_V1.32.3.bin --- + Support WIFI * Bug fixes --- RD60062_V1.32.4.bin --- * Fix TTL Interface --- RD60062_V1.32.5.bin --- + Option "SkipExitIVSet" (prevents exit from edit mode for V-SET and I-SET when press ON/OFF button). * Bug fixes --- RD60062_V1.32.6.bin --- + Option "Standby LED" (Setup the behavior of the power button LED in power off mode (Default-pulsating, 0%-off, etc...).

Option "Custom Color" allow to use selected colors (using this option you can enable/disable custom colors in bulk). Option "Test" is just temporary option and will be removed in next release, can be used to see any color and its hex value. List of colors need be adjusted, if you have any ideas just let me know (tell me hex values).

Great in dept review as usual, thank you. I have many products from RuiDeng and I am happy with all of them. This PSU seems like no exception. For the price they are selling it for, I think it is a bargain. I agree with some negative points you mention, especially the rotary click being the "escape", maybe they will fix this with a further update. But, plugging the PSU to mains when it is in power on mode as default and keeping a load attached while doing this is a no-no by all means with any lab power supply. It is a good test to see what happens when you do this, but anyone with a sane mind would not do this. Same applies with connecting the load with a turned on PSU. Using this PSU with a linear DC source as you did is the best way to go, I would not connect a switch mode bench supply to another switch mode source even if the manufacturer recommends it. I have 2 DPS5015 PSU modules from RD working on my bench at the moment and both of them get their power feeds individually from 2 quality 36VAC 400W toroidal transformers. Output AC ripple averages around 70-80mV (some occasional 100mV peeks) at 24V DC 10A load, which is fine enough for my purposes.

Would it be possible to use the guts from the Gopher to drive the RD6006? That DIY build would be awesome to watch.

Excellent video Florin! I have this PS as well and find it quite excellent for the $. The spike you see during the hard power-on may actually be your scope probe picking up the EMI from the transformer. I have the recommended switching PS in my unit, and I don't see this spike...

Good review

Thank you very much for this extensive review.

Why not use a capacitance multiplier ?

I have the rd6006p since today and I hear a faint high pitch sound when I turn on the voltage output. The sound becomes less when I increase the output voltage and from 35 volts the sound is gone. Do others have this too? Or is this a defect?

is the usb port isolated? the dps5015..5020 models had a sepperate usb-serial converter module which was isolated.

why would you EVER turn on the output by POWER switch rather than soft switch? why would you keep power delivered to the output on power on?

If you use a linear power supply a transformer bridge and large caps no fan noise at all.

I was unable to connect with the IOS app as well. Tried with several different phones.

If that is what Ruideng is using it for, I wish it hadn't a color display. My eyes hurt. It's an awesome device to charge escooter or ebike packs though, would by again. I hope there is a FOSS firmware available soon like with the Rudideng DP/DPS/DPH series before

Another great video.

Hi I am trying to use this riden rd6006 for mobile repair, and I found a short circuit in rail line that I want to inject 1.5V 2A in to what components short, but its keeping drop my volt all the way down to .5 or .6V which unusual for my case. Do you have any idea for that?

good conclusion, I cant argue with your results. Just curious but do you have any suggestions for using an oscilloscope to measure a grounded power supply? There is always alot of noise when I am probing the output of my server power supplies. My current solution is to just measure the circuits ground with one channel and in the data export subtract my other channels by it. Any other suggestions?

I would love to see the same tests with the recommended switch more power supply. How would it compare to the Gopher with that supply?

40mV ripple with no load isn't impressive taking the PSU price into account...

mine was a lot cheaper (from aliexpress not banggood) : rd6006 + S06A case : 67€ 60v - 400W PSU : 23€ total = 90 € (99 USD)
