Hi guys, I am asking for some help because I want to buy this power supply, which is incredibly cheap for its power (3000W), but the problem I have is that I need an output voltage of 22.2V, instead of the 48-53.5V it can output now.
I found this PSU, which is the same as the one in the previous link, but this one has a regulable output voltage (it has been modified by someone).
And my idea is to buy the original PSU, which is much cheaper, and modify it myself so it can output 22.2V.
I was thinking in changing the feedback voltage resistor to a potentiometer or a different resistor (I think it needs to be of less resistance?). Could that work?
In this thread can be seen some photos of its interior, but I don't distinguish very well what did he do.
My goal is to power 4 electric motors, with 22.2V and 500W of power each.
I don't have much experience with power supplies, so I don't know if buying this PSU is the right decision or if there are another ways of reaching my goal.
Also, how safe is it to modify the PSU without prior experience?
Thank you!
