Claims

[Scope of utility model registration request]

Converts alternating current supplied from commercial power source to direct current,
a charging circuit that outputs a set signal to the latching relay when the battery capacity is sufficient; a battery that charges the direct current under normal conditions; and a power supply circuit that at least stabilizes the direct current supplied from the battery in the event of a commercial power supply failure; a control circuit that controls a display, etc. and outputs a reset signal to a latching relay when the capacity of the battery is insufficient; an inverter that converts DC supplied from the battery into at least AC; A latching relay is provided between the inverters and is set in a set state by the output of the charging circuit, and is in a reset state by the output of the control circuit, a power outage signal output terminal that outputs the output of the power outage detection circuit to the outside, and a commercial power source. An uninterruptible power supply comprising: a through circuit that directly outputs alternating current supplied from the inverter; and circuit switching means that switches between the inverter side and the through circuit side.
