Scope of application and reserve time:

1, can be used for ordinary desktop computer, standby time is about 5-15 minutes, according to the desktop computer configuration power size determines how long it can take

2, super stable voltage function, for voltage instability region, can be applied between 145V-290V, stable voltage between 195-255,When the power voltage is below 145V+-5%, or above 290V automatically switch to the battery power supply, protect the computer and other equipment

3, can be used for a notebook computer for about 1 hours, according to the size of the laptop screen size

4, suitable for Internet cafes, an ordinary server or a cash register computer, power failure for 15 minutes cash collection

Calculation method of backup delay time for UPS power supply:


(battery capacity X battery operating voltage) / equipment power = extended time (hours)


For example: 500VA's UPS power supply, built-in 12V battery, 7AH, a 300W device

Calculation method: battery capacity 7AHX, battery working voltage 12V/, equipment power 300W=0.28 hours, conversion component clock is about 0.28X60=16 minutes

 

This is the theoretical value, the actual value may be small, about 10-15 minutes, depending on the actual use of the environment

Warranty: the whole machine for three years, battery protection for 1 years
