The function of the PCB

There is a PCB from my AC power supply. Here are the circuit elements for your reference: rectifier----capacitor----IC 7812----capacitor round 35V,470uF | | bridge | | | | | Transformer Relays Input from time relay EI35-220V | | | Output Output

Everything except the relays is just standard linear power supply. Then presumably the relays are controlled by something to supply 12V to something.

What I know is that the IC 7812 is a 12V regulator.

It could be switching line voltage as well. the 12v could power whatever sensor circuits there are to activate the relays.

If you can upload an image, it will be better for us to answer your question.
