Claims (1)
を検出中は蓄電池の電力をインバータにより交流
電力に変換して出力する無停電電源装置において
、 負荷の有無を検出する負荷検出手段と、 上記負荷検出手段の出力が与えられ、上記負荷
の投入、切断の少くとも一方の直後の短時間、擬
似停電検出信号を発生して上記インバータを動作
させる擬似停電検出信号発生手段と、 上記擬似停電検出信号発生中の上記インバータ

とを特徴とする無停電電源装置。[Scope of Utility Model Registration Claim] Detects the presence or absence of a load in an uninterruptible power supply that directly outputs commercial power when it is receiving commercial power, and converts power from a storage battery into AC power using an inverter and outputs it when a power outage is detected. and load detection means for generating a pseudo power outage detection signal, which receives the output of the load detection means and generates a pseudo power outage detection signal to operate the inverter for a short period of time immediately after at least one of turning on or cutting off the load. and an alarm means for comparing the output voltage of the inverter with an allowable limit value while the pseudo power outage detection signal is being generated, and issuing an alarm if the output voltage is out of the allowable range.
