please those of us who did project on automatic voltage regulators, plz can I get the circuit diagram cos the kind useless low voltage they are giving us here is alarming, I'l like the mechanical relay version which I'l adjust to use an ssr instead. I want to build one wid input from 100v to 300v, 5kva and output of ~230v. i may be ordering for the transformer but in which case i can't get it, I'l den hav 2 build the transformer myself. Thanks in advance
