Description

Not sure there is an application for this but I’ll list it anyway. It has a transformer with isolated windings for each power supply. If originally had large selenium rectifiers that produced 2 6volt power supplies both rated at 6 amps in parallel supplied 12 amps a as and in series 12volts at 6amps. The diodes have been replaced with silicon bridges so the output now at load is 10 volts and 20 volts. It could have been a battery charger but each circuit has a filter choke and there is a 2200uf / 50v cap (replaced) neither is required for battery charging. Tested 18 volts at 7 amp. No load, the cap charges to 40volts. 10 volts at 15volts. It weighs about 30# (shipping 32-35#?) It measures 11.5x 8 x 7” Thanks for looking
