Model Description

Product principle

A-D series special emergency power supply for fire emergency lamps is an emergency power supply device that provides centralized power supply for emergency evacuation lighting or important electrical equipment in buildings.

When the utility power is normal, the utility power supplies power to the load through the mutual investment device, and the charger intelligently charges the backup battery pack at the same time. When the mains power is cut off, or exceeds 20% of the normal voltage, the controller will provide the inverter signal to start the inverter power supply, and the mutual switching device will immediately switch to the output of the inverter power supply to continue to provide sine wave AC power. After the electricity voltage is normal, the emergency power supply will automatically restore the grid power supply.

Features
