ことにある。[Problems to be solved by the present invention] However, in conventional uninterruptible power supply devices of this type, the battery capacity is determined by the guaranteed power supply time to the load during a power outage.
If even one of the loads 2 requires a long-term guarantee, select a battery accordingly.
Therefore, it is an object of the present invention to eliminate the problem of the need for large capacity batteries and to make it possible to reduce the capacity of the battery without causing any practical harm to the individual loads. The purpose of the present invention is to provide an uninterruptible power supply device.

にとっての全体の負荷が減少する。[Operations and Effects] The present invention provides that, among the loads supplied with power by an uninterruptible power supply device, there are those whose guaranteed power supply time is long, those whose guaranteed power supply time is short, or those whose guaranteed power supply time is hardly required in the event of a commercial power outage. This system focuses on the fact that it is only necessary to guarantee the power supply time in the event of a power outage for each load, and multiple load circuits are provided that classify the loads into long and short periods as described above, and a The load circuit is cut off by the switch after a predetermined guaranteed power supply time has elapsed. This reduces the overall load on the battery during power outages.
したがって、従来装置に比べてバッテリー容量を削減す

Each timer has an operating time limit set according to the guaranteed power supply time in the event of a power outage, and gives a trip command to the corresponding switch when the set time limit is reached. As a result, loads requiring less power supply time are sequentially disconnected from the connected load feeder. If the power is restored during the process, all timers are reset and the feeder switches that have already been cut off are turned on again.
