An uninterruptible power supply (UPS) is designed to provide power to attached devices in the event of external power failure. It essentially acts as a backup power source, allowing devices to continue running until external power is restored or a proper shutdown can be performed. Generators are also used as backup power sources, but they are typically larger and more expensive than UPS units. Power filters and rectifiers are not designed to provide backup power in the event of an outage.
