Abstract:
1. An electronic power-saving device, comprising at least one power-saving unit which comprises: two ceramic capacitors being electrically connected in series; a safety capacitor electrically to said two ceramic capacitors in parallel, an inductor, a silicon controlled rectifier (SCR), wherein two terminals of said safety capacitor are electrically connected with anode and cathode of said SCR respectively, wherein said anode of said SCR is electrically connected to one terminal of said inductor; first and second resistors electrically connected in series, wherein said first and second resistors are electrically connected with said anode and said cathode of said SCR respectively, wherein the gate of said SCR is electrically connected with the junction of said first and second resistors; a live wire and a neutral wire electrically connected with two terminals of said ceramic capacitors respectively, and a fuse electrically connected with said live wire in series; and an indicator having a terminal electrically connected with the junction of said second resistor and said safety capacitor, a third resistor having one terminal electrically connected with said indicator in series and another terminal electrically connected with the junction of said first resistor and said inductor, and a ground wire arrangement made of metal.
