停電電源装置。 In an AC uninterruptible power supply that continuously supplies power to a load device using an inverter using a storage battery as a power source during a voltage drop or power outage of the commercial power supply, a capacitor and a relay contact are connected between the contacts of the switching device between the commercial power supply and the inverter. An arc prevention circuit is provided, consisting of a series circuit in which a discharging resistor is connected in parallel to the capacitor, and the relay contact is opened after the switch contact is completely switched to the inverter side. AC uninterruptible power supply.
