UPS (uninterruptible power supply) is an uninterruptible power supply with energy storage device. It is mainly used to provide uninterruptible power supply for some equipment with high requirements for power stability.

When the mains power input is normal, the ups will supply the mains power to the load after it is stabilized. At this time, the UPS is an AC power regulator, and it also charges the internal battery; When the mains power is interrupted (emergency power failure), ups will immediately supply 220V AC power to the load through inverter switching to keep the load working normally and protect the load software and hardware from damage. UPS equipment can usually provide protection against high voltage or low voltage. Distribution box manufacturer
