Hi!
I was in need of buying a high power 48v psu for a brushless motor driven pottery wheel project.
I needed around 20a, and everything I found was more expensive than I first thought.
I came across this unopened second hand Elteck Flat Pack S 48v 1800w for 80€. Had no clue about the brand, but was advertising 1800w 48v psu and looked pretty solid, so bought it. Was almost same price as a 20a lowest brand regular psu. (Afterwards looked for pricing, and they are pretty expensive).
The thing has arrived and I have now realised it's kind of a moldular system psu rectifier.

Found pinout and built some adaptors, all good.
The problem is that is a software regulated supply (from pc or another module), and it's actually giving 53vdc while I need 48v for my brushless motor controller.
I have seen a mod done in another serie of the same brand, just removing some resistors and installing a 50k pot, but It's just a different version and my electronics knowledge is far from reverse engineering this.

There are also mods where people builds a breakeout cable with an ic so they can control the voltage through CAN protocol.... so it seems ppl found a use for this kind of second hand psu's, but I have just found info on the Flatpack 2 series. Not the Flatpack S HE series....

Has anybody knowledge of this kind of psu? any workaround to get those 48v out?
Thanks .
