YJ-D Single- Phase Emergency Power Supply

The emergency power supply consists of inverters, transformers, chargers, battery packs, conversion relays, battery circuit breakers, mains input circuit breakers, output branch circuit breakers, and other main components.

The emergency power supply consists of inverters, transformers, chargers, battery packs, conversion relays, battery circuit breakers, mains input circuit breakers, output branch circuit breakers, and other main components. When mains power is normal, it directly outputs mains power; Simultaneously charge the battery through a charger; When the mains power is interrupted or below the set limit, the inverter starts working. The DC power from the battery is converted into AC power through the inverter and transformer to supply emergency loads with power
