Hello dear all
I'm Irfan and I have searched alot to find the the circuit that can adjust stepdownd 12V AC with 1Amp or 0.5Amp current like variac device(vary the AC voltages by using winding tapings),but i havnt found yet.Let me tel u all, mostly every where I have DC adjustable circuit with LM317 etc., 1 thing more I dont wana use transformer secondry tapings to vary the AC voltages on diffrent secondry positions I just want 12vac from 240 v main, using step down transformer and wanna make it vary...plz plz help me........
Thanking u all in anticipation....
