An uninterruptible power supply (UPS) is a power protection device that delivers a continuous supply of electric power to critical systems with two main functions:It is an emergency power system that provides a backup energy source during utility power failures. Depending on the outage duration, a UPS can keep a system running long enough until utilities or generators come online, or it can provide enough time to shut down the system properly and avoid data loss.It protects against power surges and sags that could damage sensitive electronic hardware.
