Overview

It can be divided into AC output (JC-D)和DC output(ZC-D), and provide emergency power to keep system normal working for evacuation lighting and indicator lights when in lack of city power. This centrally connected power source is DC output type with 220VAC/216VDC (216VDC when in emergency).
Features
1、Rectifier module adopts the international forefront PTR soft switch technology with high efficiency and reliability. The unique deep discharge capacity makes the lead-acid battery have more than three times of service life when on EPO emergency startup.
2、Using the latest fire prevention corrosion resistant material with professional fire prevention safety design to keep away from fire hazards.
3、Easy to maintain, can be monitored by computer, automaitic switch between external power grid and the battery, unattended operation, mutual switch time ≤0.25S.
4、Smart battery management: can adjust number of batteries, battery voltage (upper and lower limits), set the battery failure recovery voltage (upper and lower limits), set up regular battery testing, the battery voltage, battery failure alarm, etc.
