Product Description
EPS power supply, also known as fire emergency power supply, with the full name of Emergency Power Supply (EPS), is an emergency power supply adopted in important buildings nowadays for power guarantee and fire safety. It mainly consists of input and output units, charging modules, battery packs, inverters, monitors, output switching devices, etc. It is widely used in chemical plants, oil fields, hospitals, schools, shopping malls, stadiums, exhibition centers, financial systems, subways, high-speed railway stations, tunnels, expressways and other places.
Product Application
Designed specifically for fire emergency lighting or other primary load power supply, it provides centralized emergency power supply for safe evacuation and rescue in case of emergency within buildings.
Product Features
1. It adopts imported IGBT/IPM intelligent power modules, featuring high reliability.
2. It employs advanced DSP digital control technology to provide pure sine wave output.
3. It is equipped with a forced emergency start switch and an automatic/manual switch.
4. The monitoring system uses fully Chinese LCD liquid crystal display, making system operation data clear at a glance.
5. It has fire linkage control and fire center control functions.
6. It features fully automatic intelligent battery management function.
