  • Page 9: Modes Of Operation

    Modes of Operation INPUT FILTER INTERFACE Normal Mode The Power Module rectifiers derive power from a utility AC source and supply regulated DC power to the inverter. The module’s inverter regenerates precise AC power to supply the connected equipment. The battery charger is in the Power Module and maintains a float-charge on the batteries. Backup Mode When AC utility fails, the connected equipment is supplied power by the inverter, which obtains energy from the Battery Modules.
