To prevent electrical power from being supplied from the backup power supply (14) to a load circuit (2), during a normal operation, a power supply control unit (11) gives a standby instruction to the backup power supply (14) so that the backup power supply (14) is on standby at a voltage lower than that of the main power supply (13). When an AC power supply (1) is stopped, the backup power supply (14) is operated at the set voltage and the main power supply (13) is stopped.",
