Recently on AliExpress, eBay, etc... I've seen server power supplys normally an HP DPS-750/1200 or very similar and they have a module connected on the outside which must be a CC/CV controlling device... (attached images below)
They're littered all over AliExpress. I searched all over Google and I can't find anything similar or any information whatsoever. There is a bunch of info on changing the output voltage slightly but that's about it.
I've also looked for the module itself for sale everywhere but can't find anything.
I was just able to find a picture of the internals and the PCB. It looks fairly simple. 1 IC, and a couple pots....
So it's seems that there somehow able to control the cc/cv internally on the power supply itself and not using an external cc/cv buck/boost module.
If anyone understands how this thing is working or know where to find any information or where to buy one please leave a comment below.
