| Function & Characteristic
1.Main circuit is controlled by microprocessor(CPU)
2.The performance of circuitry is controlled by microprocessor to avoid any interruption of power supply.
3.LED status display.
4.AVR function
5.Over-discharge protection: After battery discharged, UPS will cut off the power and battery stop discharging. When Mains recover, UPS can autostart and charge the battery instantaneously, no harm to battery.
6.User-Replaceable Battery Design.
7.Cold start function(DC power on).
8.Provides lightning, surge, overload and short-circuit protection.
9.Automatically fault checks when starts, to increase the rate of safe use.
10.Special design of the charging mode, even when UPS is in fault or shut off, the charging circuit can still work properly and adjust the charging mode(Floating charge or continuous charge)to prolong the working life of the battery.Primary Technical Parameter
