UPS power supply
UPS (Uninterruptible Power System), i.e., uninterruptible power supply, is a kind of constant voltage and constant frequency uninterruptible power supply containing energy storage device, with inverter as the main component. It is mainly used to provide uninterrupted power supply to a single computer, computer network system or other power electronic equipment. When the utility input is normal, the UPS will be the utility voltage regulator to supply the load, the UPS is an AC utility regulator, it also charges the battery; when the utility interruption (accidental power failure), the UPS will immediately battery power, through the inverter conversion method to continue to supply the load 220V/380V AC power, so that the load to maintain normal work and protect the load software and hardware from damage. UPS equipment usually provides protection against over-voltage and under-voltage.
