An uninterruptible power supply (UPS) is a device that allows your computer or telephone switch or critical equipment to keep running for at least a short time or longer time when the primary power source is lost. It also provides protections from power surges, spikes, brownouts, interference and other unwanted problems on the supported equipment.
