Brief introduction
A application: three phase EPS is reserve power supply equipment installed in buildings. When there is no commercial power in a building because of fire, accident or other emergency, EPS supplies the second way emergency power for fire-fighting identification light, headlight, fire pump, rolling door and other important loads. As the increasing of building fire safety level, especially there are more high buildings, centralized power supply EPS has became indispensable equipment in buildings.
B install type console model
C reserve time 90 minutes， national standard （reserve time can be settled by designed requirements）
D series 2.2、3.7、5.5、7.5、11、15、18.5、22、30、37、45、55、75、90、110、132、160、187、200、220、250、280、315、355、400、500（unit kW）
Characteristics
1. Emergency power supply---it will supply 220V/380V 50 HZ sine three phase AC emergency power to ensure fire fighting light and other important loads working normally when commercial power is off or voltage is beyond range.
2. High performance---SPWM high frequency contra variant technology, good quality of power supply, suited for various kinds of load
3. High reliability--- advanced technology and redundant design, multi-CPU control, made by good quality component accurately, stable function and high reliability
4. Completed protection--- good overload output protection, short circuit protection, battery reverse connection protection, over discharge protection, high anti-abuse ability
5. friendly interface--- LCD display the information of working condition clearly, commercial power voltage, output voltage, current, frequency, battery voltage, on load ratio, error and etc. it can warn sound and light error, indicate error type and eliminate error noise.
6. High ability of charge--- large current charger with auto charge technology, charge in high speed, stable floating voltage
7. Simple structure--- module design, simple structure, convenient maintainance
8. Remote monitoring--- RS232 or RS485 digital communication interface, standard MODBUS communication agreement, EPS remote computer centralized monitoring and management
9 intelligent battery management--- intelligent battery monitor management components, strengthen battery monitor, lengthen battery using time and increase availability ratio
