STPS-KN Quick-switching emergency power supply
Product Description
EPS power supply, also known as fire emergency power supply, with the full name of Emergency Power Supply (emergency power supply), 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, sports venues, exhibition centers, financial systems, subways, high-speed railway stations, tunnels, expressways and other places.
Product Application
The fast-switching EPS power supply is specifically designed for primary loads, fire protection facilities, fire emergency lighting, or other equipment that requires uninterrupted emergency power supply. In the event of abnormal mains power, it provides centralized and uninterrupted emergency power supply for the electrical load.
Product Features
The switching device uses static thyristor switching, which has a fast switching speed.
2. Utilizing imported IGBT/IPM intelligent power modules, ensuring high reliability
3. Utilizing advanced DSP digital control technology, providing pure sine wave output
4. Equipped with a mandatory emergency start switch and an automatic/manual switching switch
5. The monitoring system uses fully localized LCD liquid crystal display, making the system operation data clearly visible at a glance.
6. Equipped with fire linkage control and fire center control functions
7. Fully automatic and intelligent battery management function
Product advantages
1.The switching time is short, enabling uninterrupted switching.
2. Fully digital control, automatic switching, achieving unmanned operation
3. Simple design, easy construction
4. Stable performance, safe and reliable, long service life
5. Energy-saving. When not in emergency power mode, it consumes almost no electricity.
6. Maintenance-free battery, capable of being recharged up to 300-500 times.
