Boosting voltage on Elcon with external PSU
« on: January 09, 2018, 04:25:27 AM »

I got a deal on a pair of Elcons to charge my homebrew bike. Elcon PFC-2500s, TCCH-60-35. The chargers are 80v max voltage, and for my 24s LiFePO4 pack, I need to get up to at least 85v or so to charge. I have been thinking of wiring an external PSU in series to get to voltage where I need it, probably a 12v one. Getting a 12v/35A PSU for each won't be too hard. Maybe even a 12v/70A one I can use for both, if possible, for simplicity- not sure if that'd work.

Anybody know if the outputs of the Elcons are isolated? That'd make things easier. Anybody done something like this before?
