Of course, the uninterrupted power supply time of UPS is not unlimited, which is limited by the storage energy of the battery itself.
UPS (Uninterruptible Power Supply) is a system equipment that connects the storage battery (mostly lead-acid maintenance-free battery) with the host computer, and converts DC current into market electricity through module circuits such as host inverter.
The main advantage of uninterruptible power supply is its uninterrupted power supply capability. When the AC input of municipal power is normal, UPS rectifies AC to DC, and then inverts DC to stable AC without impurities, which is used for the later load. Once the AC input of city power is abnormal, such as under-voltage or power failure or abnormal frequency, UPS will turn on the standby energy-storage battery, the rectifier circuit of UPS will turn off, accordingly, the DC inversion of the battery will become stable AC without impurities, and continue to be used for the later load. This is the origin of UPS's uninterrupted power supply capability.
Of course, the uninterrupted power supply time of UPS is not unlimited, which is limited by the storage energy of the battery itself. If AC blackout occurs, then in the precious time of UPS battery power supply, what you need to do is to restore AC as soon as possible, such as starting the alternating current backup circuit and turning on the oil engine to generate electricity. It is really not possible, so you have to save the work results urgently and wait for the alternating current to return to normal before continuing.
