The UPS uninterruptible power supply is equipped with a set of battery packs. When there is no power outage, the internal charger charges the battery pack. When it is fully charged, it enters the floating charge state and maintains the battery. When the power unexpectedly ends, the UPS uninterruptible power supply immediately switches to the inverter state within milliseconds, converts the power in the battery pack to 220V AC, and continues to supply power. At the same time, the UPS uninterruptible power supply emits an alarm sound to indicate power interruption. During this period, the user has almost no impact other than hearing the alarm. The original equipment is still in normal use and is not affected at all.

 

However, it should be noted that the UPS uninterruptible power supply time is not unlimited, this time is subject to the size of the battery itself to store energy. If an AC power outage occurs, all you need to do in the precious time of the UPS battery power supply is to restore the AC power quickly, such as enabling a standby AC power circuit and enabling the oil generator to generate electricity. If this is not possible, you can only save the emergency disk, save the labor results, and wait Continue after the AC power returns to normal.

 

The main advantage of uninterruptible power supply lies in its uninterruptible power supply capability. When the AC input of the commercial power supply is normal, the UPS rectifies the AC power into DC power, and then inverts the DC power into stable AC power without impurities, which is used by the subsequent load. Once the mains AC input is abnormal, such as undervoltage or power outage or abnormal frequency, the UPS will activate the backup energy-battery, the rectifier circuit of the UPS will be turned off, and accordingly, the DC power of the battery will be inverted to a stable Impurity alternating current, continue to be used for the subsequent load. This is the origin of UPS's uninterruptible power supply capability.

 

Of course, the uninterruptible power supply time of the UPS is not unlimited, this time is subject to the size of the energy stored in the battery itself. If an AC power outage occurs, all you need to do in the precious time of the UPS battery power supply is to restore the AC power quickly, such as enabling a standby AC power circuit and enabling the oil generator to generate electricity. If this is not possible, you can only save the emergency disk, save the labor results, and wait Continue after the AC power returns to normal.
