Both my DP and DPS power supplies are still working great, they have gotten very regular use for over a year now.
I have also been using the USB 3.0 tester and USB load source quite a bit recently as I hunt down the best USB power bank. Do you have one that can measure more then 3A of current?
Does the communication version of the power supplies allow logging on the computer yet?
thank you very much for your support and your message
for now there is no better one , max current is only 3A, the communication version still did not have this function
I have pictures of the setup
Anyway as seen in the pictures the screen of the DPS shows the output voltage only the output current(yellow) and output power (purple)are both at 0.00.
Also when trying to use other preconfigured options like M1…9 it’s reverting back to M0.
Up on top next to Set it shows what I programmed in volts and amps not at the output area.
Does anyone know why this happens? Thanks in advance and let me know how to input pictures.

could you make a video to show the problem, your picture is too blur, I can’t see it clearly
and please contact me by email 1749808860@qq.com, ok?
Nice power supplies, the screen makes it a bargain. But why so low frequency?
I wanted to drive power leds in cc mode. Given the fact that unit has very nice color screen!
Specialized LED drivers like the LED2001PHR work at 850khz fixed frequency so you don’t ever get flicker even on camera.
Is RDtech willing to release series for LED driving? Like RGB, RGBW versions would be awesome.
Even upgrading switching frequency on current units would be good enough for me.
you can connect the LED directly … only the current is closed to resolution , it will blinking
for example , DPS5015, the resultion is 0.01A, if the current is 0-0.05 , it will be blinking … when the current is more than 0.1a , it will not be blinking …
for DPS5005, The resolution is 0.001A, at 0-0.005, it will be blinking, more than 0.01A, it will not be blinking
so the resolution will affect this …
re the DPS5015, which I ve noticed there is not much referene to!
I have riged up a DPS5015, and it is working ok, loaded at 3 amps.
But, the fan is not moving.
My question, which , so far, no one has been able to answer, is “should the fan work all the time, or only at a certain temperature”?
I just spotted this DPH5005. Buck/Boost and up to 10A on the input side. Looks like a nice unit but I honestly wish it was even more powerful and could go up to 80vdc on the output to drive some of the new ~72vdc COBs.
I may still get one to use with some of my 36-40v COBs.
