24v 3a Power Supply Circuit Diagram. Do not try to connect 24v dc instead of ac becouse it does not work with dc voltage at the input. The double π type filter network composed of c1 l1 c2 and c3 mainly suppresses the electromagnetic noise and clutter signals of the input power source to prevent interference to the power supply and it also prevents high frequency clutter generated by the power supply itself from interfering with the power grid.

The circuit shown in the diagram above is a classic design may be used as a 12 volts dc power supply source for most electronic circuits. Input filter circuit.
