What Does Uninterruptible Power Supply Mean?

Uninterruptible Power Supply(UPS) refers to an electric equipment system that can provide stable power to equipment when the power grid is out of power or the voltage is unstable. It is usually powered by a battery pack or other backup power source, and can immediately switch to the backup power source to provide power when there is a power outage or voltage fluctuation, thereby ensuring the normal operation of the equipment and avoiding equipment downtime or data loss. UPS stores electrical energy in the form of DC in the battery through internal components such as rectifiers, inverters and static switches, and outputs voltage to the outside in the event of an external power failure, achieving uninterrupted power supply.
