An uninterruptible power supply, often known as a UPS, is an electrical device that supplies backup power to connected loads in the event of a power outage. It uses a backup battery to provide power until the main power is restored. UPSs are placed between the conventional power source and the load, with the provided power flowing through the UPS before reaching the load.
