る無停電電源装置。 A charging circuit that converts at least alternating current supplied from a commercial power supply into direct current; a battery that stores the direct current in normal times; a power supply circuit that at least stabilizes the direct current supplied from the battery in the event of a power failure; and a display. an inverter that converts the direct current supplied from the battery into at least alternating current; and an inverter provided between the battery and the inverter, and when the capacity of the battery is sufficient, it is in a set state, and the capacity is increased. a latching relay that enters a reset state when the voltage is insufficient; a through circuit that outputs AC supplied from a commercial power source as it is; circuit switching means that switches between the inverter side and the through circuit side; and a circuit switching means that detects a power outage. An uninterruptible power supply system comprising a microprocessor that resets the latching relay and transmits a power failure report to a computer via an RS-232C signal line or a light pen signal line.
