Abstract
PURPOSE:To contrive out-of-reference direct-current not to be fed to a load from a storage battery, by setting a means for keeping a separated state till an AC power source is recovered when the back-up storage battery comes to threshold voltage once and is separated from. CONSTITUTION:DC power is fed to a load 300 from an AC power source 100 via an AC/DC converter circuit 200 and a breaker 12, and a storage battery 3 is charged. When the AC power source 100 is service-interrupted, then current is fed to the load 300 from the storage battery 3, and when the output of the storage battery 3 comes to threshold voltage, then the breaker 12 is automatically worked, and the storage battery 3 is contrived to be separated from. In its case, if the storage battery 3 is separated once by a storage battery switching means 400, its state is kept till the AC power source 100 is recovered. In such a case, the storage battery 3 is not re-connected in the state of capacity shortage, and the load can be protected.
