Centralized EPS for Fire Emergency Lighting Power Supply

Product Overview

Langrui fire emergency power supply is mainly used in public buildings to provide emergency power for fire emergency lamps or fire-fighting equipment, serving as an indispensable part of fire protection facilities. There are two main types of fire emergency power supplies: fire emergency lamps (0.5KW-95KW) with a national standard emergency duration of no less than 90 minutes (customizable upon customer request), and emergency power supplies for fire-fighting equipment (0.75KW-200KW) with a national standard emergency duration of no less than 180 minutes (customizable upon customer request).

Structural Features and Working Principle

Langrui centralized power supply for fire emergency lighting is a power supply device that provides centralized power for emergency evacuation lighting or important electrical equipment in buildings. When the municipal power supply is normal, the municipal power supply supplies power to the load through an automatic transfer device and intelligently charges the standby battery at the same time. When the municipal power supply cuts off or the voltage exceeds 20% of the normal value, the controller sends an inversion signal to start the inverter power supply. Meanwhile, the automatic transfer device will immediately switch to the output of the inverter power supply to continuously supply sine-wave alternating current. After the municipal power supply voltage returns to normal, the emergency power supply will automatically restore power supply from the grid.
