PURPOSE: To provide a power supply in which a sufficient capacity can be set depending on the load while allowing subsequent increase of power capacity in response to increase of load capacity. CONSTITUTION: The power supply unit 2. comprises a charger 10, a battery 12, a booster 13 and an inverter 14 wherein an AC output receptacle 9 can be fed with power on a feeder line L1 directly from a commercial power supply or through an inverter. Consequently, a small capacity load can be backed up only through a single power supply unit 2. When a plurality of power supply units are connected, the operation is controlled appropriately through a control section 15 thus driving a load stably. Since the capacity is the sum of batteries mounted on respective power supply units, even a high capacity load can be backed up. COPYRIGHT: (C)1995,JPO ...
