Hi,
Just salvaged the transformer from APC UPS BE500-IN 500VA. Can I use it to build a power supply?
My interest on this transformer is for the high current rating (we all need one for high power projects). Should the idea be legitimate, the secondary of the transformer can be connected to AC wall outlet to get at least 12+12VDC 10A current and cut costs on switching power supplies for our laboratories.
The positive terminal of the battery is connected to the centre tap of the 12-0-12V primary alone. Tracing the circuit suggests some half-wave rectifier system keyed from a relay. Obviously, the battery is charged from steeped-down AC wall outlet supply somehow and the absence of any other transformer points to my apprehension.
Please advise...
