Emergency power supplyalso known as EPSis designed specifically for
fire fighting equipment and specialload or lighting purposes. When
the power network voltage is normal the power supply of the
electric network is directly supplied to the load by the mutual
switching device of the power gridand the charger in the device can
charge the battery pack.
When the power supply is cut off or the power network voltage iS
less than 15% or more than 10% of the rated voltagethe device will
immediately switch to the inverter output power supplyBattery
backup power by the inverter AC continue to provide power to the
load. When the power network voltage is normal.
the equipment will be restored to the power grid. In order to meet
the demand of power supplythe device is equipped with a baery pack
under voltage protection to remove the switch.
