Can meet the power supply needs of microcomputer protection devices, indicator lights, and analog indicators; When powered by batteries, it can last up to8～24Hour.

Short term operating power: ≤600W，30S.

satisfiableVS1TheVD4TheZN21Waiting for the majority10KVThe system's circuit breaker and electric load switch require energy storage and power supply.

Instantaneous operating power: ≤1000W，100ms.

satisfiableVS1TheVD4TheZN21Waiting for the majority10KVThe power supply needs for the opening and closing of circuit breakers and load switches in the system's operating mechanism; Operable when powered by battery backup20More than once.

（2）Power consumption: The power consumed by the device itself is not greater than8W.

4. Charging and discharging of batteries

External connection of the device2section12VBattery, when the AC power supply of the device is cut off, ensures the normal and continuous DC power supply. The specific backup time is determined by the battery capacity and load size. When the battery is dischargedElectricity to overvoltage and undervoltage（23V）At this time, the device emits an alarm signal and automatically stops the DC output to protect the battery; When the AC power supply is normal, the device automatically restores the DC power supply and72The battery can be recharged within hours.
