った。When a power failure occurs, the power failure detection circuit 6 immediately sends a power failure signal to the power failure detection circuit 7 and the load 10. The inverter unit 4 converts the DC energy of the battery unit 5 into AC energy and supplies the load 10 with power via the output terminal 2. At the same time, the AC switch 3 is in the off state. In the power failure operation, the load device receives the power failure signal 8 sent to the load 10, and the load device enters the power failure saving process. Generally, if the logically disconnection of an external storage device such as a hard disk is included in the evacuation process during a power failure, it is difficult to interrupt the evacuation process even if the power is restored, and it is not possible to restart after the evacuation process is complete. , Requires an initial process for logically connecting an external storage device. Further, the initial process is usually included in the reset start process at power-on. However, in the conventional device, when the power failure is recovered, the inverter operation is stopped, the AC switch 3 is turned on, the power is immediately switched to the commercial power supply, and the load power supply is continued as it is. Had to be stopped and then repowered. Therefore, unattended operation of the load is difficult, and there is a waste that the load cannot be used until the operator operates it even though the power is restored.

Power the load m. On the other hand, in the RS232C control unit of h, the signal k
In response, the load device sends a power failure detection notification to the load m, and the load device receives the power failure detection notification and starts power failure processing. As shown in Fig. 3, when power is restored within the load power supply stop delay time that has been set and stored in advance, that is, the backup time T1,
By stopping the inverter operation and turning on the AC switch c, the load power supply by the direct transmission of commercial power is continued. After the backup time T1, the AC switch d is turned off to stop the load power supply, and the pre-stored restart delay time T2 at power recovery is stored.
Is started, and after the lapse of T2, the AC switch d is turned on to re-power the load from commercial power. This enables the load to start initially. When the power is not restored within the load power supply stop delay time, that is, the backup time T1, the inverter operation is stopped until the end of counting T1 and then the inverter operation is stopped by the inverter stop signal I. Since the AC switch d is turned off only during counting of T2, it is turned on at the time of commercial power recovery and the restart is performed without any problem.
