    Advantage

    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 mutd.
     
    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 misoperation 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.

    How to choose suitable inverter?
    If your load is resistive loads, such as: bulbs, you can choose a modified wave inverter. But if it is inductive loads and capacitive loads, we recommend using pure sine wave power inverter. For example: fans, precision instruments, air conditioner, fridge, coffee machine, computer, and so on. Modified wave can be started with some inductive loads, but effect for load using life, because capacitive loads and inductive loads need high quality power.   How do I choose the size of the inverter? Different types of load demand for power are different. You can view the load power values to determine the size of the power inverter. 
    Notice: resistive load: you can choose the same
