Is there anything we can do to lower the ripple? Better and bigger capacitors?
Trying to modify this module is not worth it IMO. Either get one of the smaller units or if you need accuracy, power and stability it is time to get a better unit.
I have a dp50V5A and the DPS5015. The combo works well together. I do not need lower ripple when over 5A for anything I do and when I am under 5A I have the smaller unit with only ~13mv of ripple.
Received the case this weekend for my 5015, it’s a nice little unit, quite a snug fit but it keeps the whole thing compact.
Also grabbed a 5005 and a couple more of the USB meters he sells on the Ali store, great little units those :+1:
TBH I can’t say, I assume it should be on constant but mine didn’t work when I first assembled it. I won’t get a chance to look again for at least a week as I’m away working.
A small board attaches directly to the input posts to give power for the fan but I guess I connected it wrong. Looks like a small connector should be provided but it is missing and needs to be soldered.
Video showing case
I use the Dell EPS-470 as a DC power source for my DPS 5015, and the fans on it are much louder than the fan on the DPS5015, FWIW. The volume of the EPS-470 fans is probably the only part of this budget setup I don’t like, in fact. But if that’s my only complaint, that’s not exactly a dealbreaker.
Sorry, you are correct I did not understand the question properly. No input from me in that case.
I recall reading a warning that when switch mode power supplies fail, they fail ugly, often destroying the equipment they’re connected to.
Transformer-based power supplies will also produce far less radio noise than most switch mode supplies.
Starting to run a radio frequency noise source is a good way to arrange to meet your local ham radio operators, though.

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 really like DPH5005 that’s what I needed, specially communication version.
Ordered one 
thank you very much for your support
hope you like it
I bought the DPS30V12A
https://www.ebay.com/itm/DP-30V-12A-Constant-Voltage-Current-Step-down-Programmable-Power-Supply-Module/122157173395?epid=546075462&hash=item1c71228a93:g:C2YAAOSw4shX7MrX
and am using the 9.7A 350W Regulated Switching Power Supply from Genessi
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 …
how can I connect bluetooth module ?
I cannot find any documentation on that subject.
I have DSP5005 with communication modules; USB works just fine but I cannot get Bluetooth module to work with DPS5005 PC Software V1.3.
How does blue-tooth module connects to DSP 5005?
Any information is welcome.
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”?
In the models I have tested the fan start above a certain current, but also on temperature.
