Uninterruptible Power Supply

Uninterruptible Power Supply(UPS) is an uninterruptible power supply with energy storage device. It is mainly used to provide uninterruptible power supply to some equipment with high requirements on power supply stability.
When the mains input is normal, UPS stabilizes the mains and supplies it to the load. At this time, UPS is an AC voltage stabilizer, and it also charges the battery inside the machine; when the mains power is interrupted (accidental power outage), UPS immediately switches the DC power of the battery to the load through the inverter switching method to continue to supply 220V AC power to the load, so that the load maintains normal operation and protects the load software and hardware from damage. UPS equipment usually provides protection against overvoltage or undervoltage.
