Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power supply control device high in usability that can restart the operation of a drive part of an electric product or the like when a voltage to be applied is returned to a normal state even if the voltage is erroneously applied to a power supply device of the electric product such as a heat pump hot-water feeding machine, in the work of the exchange or the like of a meter. SOLUTION: The power supply control device comprises: a voltage conversion circuit 2 that converts an AC voltage to a DC voltage, a power supply measuring circuit 3 that measures the DC voltage after being converted by the voltage conversion circuit 2, and the drive part 8 that is driven by the DC voltage. The power supply control device is also characterized in that: when a DC voltage value measured by the power supply measuring circuit 3 differs from a rated voltage value of the drive part 8, the drive part 8 is stopped and the DC voltage value is continuously detected by the power supply measuring circuit 3, and when the DC voltage value is returned to the rated voltage value, the restart of the operation of the drive part 8 is continued.
