An uninterruptible power supply (UPS) or uninterruptible power source is an electrical apparatus that provides emergency power to a when the input power source or fails. A UPS differs from an auxiliary or or in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteri.

The on-battery run-time of most uninterruptible power sources is relatively short (typically ranging from 5 to 15 minutes) but sufficient to start a standby power source or properly shut down the protected equipment. [2] It is a type of continual power system. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide. . Uninterruptible Power Supply Run Time is the length of time a UPS system can provide backup power to connected devices during a power interruption. This run time acts as a buffer, giving users the chance to shut down sensitive equipment safely or switch to an alternative power source, such as a. . The runtime of a UPS determines how long it can stay on powering your devices before its internal battery runs out. It tells you when you must either shut down your electronics properly or find a more sustainable backup energy solution. Typically, an uninterruptible power supply has a finite backup time.
