1. Wide range of input voltage

The UPS can offer normal and stable service voltage under its input voltage range. When the input voltage is out of its range the machine will switch to battery mode automatically to keep the output power in order to protect the equipment, such as computers, ensure they will not be damaged by the over high or over low voltage, users can continue the operation of equipment for a while or save the data on computers while the power network is abnormal.

2. Wide range of AVR(Automatic voltage regulation)

In the product’s input voltage range and under 3 steps of intelligent AVR function, it can provide a stable output voltage.

3. Automatic self detection when UPS on(LED).

Before the UPS on, red, yellow, blue LED will light up two times by cycle turns, after self detection UPS switch to AC mode/battery mode or working mode.

4. Silence function

In the "battery mode", shortly press the switch to turn off the buzzer. But the battery is about to run out or the load is too heavy, the buzzer sound cannot be muted.

5. Overload protection

In the battery mode, output voltage turn down correspondingly when it is overload, after the capacity of load is lower than the rated power then output voltage will back to rated value, it ensures the UPS will not shut down by abrupt overload which caused by surging current during the computer is working and other equipment is added.

6. Short circuit protection

When the mis-operation caused the load short circuit or computer failure (such as power tube breakdown of switch) cause short circuit, the UPS will shutdown automatically for protection.

7. The low current switch

This UPS adopts low current switch to extend the service life which is longer than conventional battery and high current switch in AC current path.

8. Automatic charging

There are two charging mode, charging time is faster than ordinary charging mode, higher efficiency, and greatly prolonging the service life of the battery.

9. With a bypass output

Independent bypass output socket for external printers or scanners of computer peripherals, with surge protection of the load.

2. Warranty of Unipower Products
