Emergency lighting centralized power supply (dedicated emergency power supply for fire emergency lighting fixtures)

Product Overview

The emergency lighting centralized power supply (specialized emergency power supply for fire emergency lighting fixtures) is a dedicated power supply equipment for the I-EIS intelligent evacuation indication system (hereinafter referred to as the emergency power supply), providing working power for the distribution devices in the area. Under normal circumstances, AC mains power is supplied to the load through the interconnection device. When the AC mains power is cut off, the interconnection device will immediately switch to battery pack power supply. When the mains voltage is restored, the emergency power supply will be restored to mains power supply. The centralized power supply communicates with the emergency lighting controller through the RS485 bus, transmits operational information to the emergency lighting controller, and can accept remote control from the emergency lighting controller.
