Emergency Power Supply (EPS)
Product Overview:
The LY-D series single-phase emergency power supply is designed in accordance with GB17945-2010 "Fire Emergency Lighting and Evacuation Indication System" standards. It is manufactured using modern power electronics and control technologies, with battery as the power source and inverter as the core component. This AC power supply equipment integrates functions of inversion, charging, centralized control, and detection.
The LY-D series single-phase emergency power supply produced by our company is a device designed to provide backup power for single-phase lighting loads. When power failure occurs due to fire, accidents, or other emergencies, the emergency power supply can provide emergency power for fire exit signs, lighting fixtures, and other critical loads. With the improvement of fire safety standards in various venues, especially in high-rise buildings, large stadiums, and rail transit systems, emergency power supplies have become essential fire safety equipment. The device consists of an inverter, charger, battery pack, controller, and switching mechanism.
