    I have 24vdc, 20A battery charger. Now I need a 125vdc,10A charger. May I convert my existing 24vdc into 125vdc charger

    Your unit is built with power transformer-power semiconductors-power diodes and E-caps that max out at 480 Watts power capability.
    Your request would be demanding a total of 1,250 Watts . . . . . .no can do.

    There seems to be two posibilities.
    1. Rewind the transformer to give the required voltage (expensive) and change the diodes (cheap).
    2. Add smoothing capacitors (1mF/A?) and use a boost convertor. I have not investigated high power convertors.

    Just out of curiosity, what are you going to charge with a 125V charger?
