Power supply options

The general rule of thumb for PFC supplies is 25% combined efficiency losses for the supply and charger. That puts you just over 2000 watts / 18.8 amps AC at the outlet.

Unclear. I left them running overnight (which I've done before, they're so quiet I forget they're running) and when I ran a charge the next day I noticed some very disconcerting arcing. Quickly shut down and unplugged everything. Inspection showed one of the ring terminals on one charger overheated so much it melted the plastic mount and forced the eyelet to have a poor connection with the post (causing the arcing.)

I tested all the supplies individually and they all still worked. But since then whether I run all three, two, or just one, at least one of the supplies will start to overheat at a terminal post and I have to abort.

I still have the supplies if you want to play with them.
