I need a low frequency toroidal transformer and I intend to make it myself, need a 50V 2A output from a 220V input., any idea on how to make this? help is much appreciated!
If the frequency is 50 or 60 Hz a 240 volt autotransformer will work. Wind the appropriate number of turns of wire on it. Number 18 wire is adequate for 2 amps RMS. Insulating tape should be wound over the primary before the secondary is wound.
