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.
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.
The more you boost voltage the less current it can output and the lower the efficiency is.
Making it a boost driver would overcomplicate things and just make it worse.
Get a good 80V power supply and just use the DPS.
Lets be honest here. This is a flashlight forum and you’re suggesting that I use something that requires AC? If I wanted to do that, I could just buy a MeanWell HBG series LED driver/PSU.
The DPH series might be inefficient but it is potentially portable and it is flexible enough that I should be able to drive most any COB with it for testing.
These DP power supplies are meant to be bench top power supplies.
If you want to build some giant flashlight with this instead of a regular LED driver then you just need to have enough batteries to reach 80V+ or use a DC to DC power supply. It doesn’t have to be AC. The DPS has DC input.
