How it works power saver?This circuit of works to filter the AC voltage , and reduce the magnitude of the cosine curve AC current that will be read on the instrument KWH meters. KWH meters will work if there is a load wire passing through a coil of wire sensors to measure the AC current is passed, if the current through a lot of electricity. C1 and C2 worked as a deduction from stamping voltage if the switch is connected, so that equipment or components which enter the voltage was not much shocking.
Part List simple power saver circuit:C1,C2 = 100pF / 400V or higher
C3 = 10uF / 400V non polar capacitor
Fuse = 0.5W
S1 = Switch on/off
Use best quality capacitors
Circuit can use to many electronic device such as power amplifier circuit , power supply , etc.
Danger ! see the circuit clearly to operate it
