Hello,
i found a circuit (soldered PCB) in my college. I have drawn the circuit and attached.
The circuit consists of a 230/12v T/F, rectifier, 7812, 7809, 7806 and 7805.
all the outputs of regulators are connected to a rotary dialing switch. and a single output is taken out. By rotating the switch, we can select the desired voltage.
That output connection is given to a transistor circuit. what is that circuit meant for? Is it a overload protection circuit?
thankyou
