Claims (1)
源より蓄電池に切り替えることによつて、蓄電池
を電源としてインバータから負荷装置へ継続して
電力を供給する交流無停電電源装置において、蓄
電池を電源とする電力供給時間を、蓄電池が放電
終止電圧に達するまで、または常用電源の電圧低
下もしくは停電時より一定時間のいずれかに選択
できるようにしてなる交流無停電電源装置。 In an AC uninterruptible power supply that continuously supplies power from the inverter to the load device by switching from the regular power supply to the storage battery during a voltage drop or power outage of the regular power supply, the power supply uses the storage battery as the power source. An alternating current uninterruptible power supply that allows the time to be selected from either until the storage battery reaches its final discharge voltage, or from a certain period of time after the voltage drop or power outage of the regular power source.
