The Most Comprehensive Knowledge Collection In The History Of Ups Uninterruptible Power Supply!

Uninterruptible Power Supply(UPS), is usually one of the subsystems of the weak current room engineering. It connects the battery to the host equipment and is mainly used to provide stable and uninterrupted power supply to the equipment.

When the mains input is normal, the UPS stabilizes the mains and supplies it to the load. At this time, the UPS is an AC voltage stabilizer, and it also charges the battery inside the machine. When the mains power is interrupted (power outage), the 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. Let's take a look at the basic knowledge of UPS.
