Beschreibung
Zusammenfassung:	The utility model discloses an electrification indication power supply circuit. The circuit comprises a rectification unit, a conversion control unit, a power adaption unit and a locking unit which are sequentially connected, wherein the rectification unit comprises a step-down switch power supply which is connected with a resistor and diodes in series. According to the utility model, the step-down switch power supply is additionally arranged in the rectification unit, so that the voltage is reduced by the switch power supply, and the problems of using a resistor to reduce the voltage, such as the stability is poor and components in the circuit are burnt by the heating of the resistor, are solved.
