Here introduces a satellite receiver remote control AC on/off circuit, it can be fixed in the receiver, and use former remote controller to realize remote control delay AC on/off function. This circuit has simple structure, easily purchased component, simple manufacture, specially suited for unprofessional electron fans to make.Work principle: The circuit is shown as figure 1. Commercial power is stepped-down by transformer T, and be commuted by rectifier diodes D1-D4, and be regulated by voltage regulator block 7810, 7805, and be filtered by capacitance C1, C2, C5, C6, then it supplies power for the entire circuit.
