Definition[edit | edit source]

An Uninterruptible Power Supply, also called a UPS, is a device that supplies power to a connected load when the main power source is removed, usually through application of a battery that is otherwise charged from the main power source. This can be used to ensure enough time for a power down sequence, a bit of extra work time, or even an interim supply of power while switching from one power source to another. Typically, the device uses a sealed lead acid battery, but other technologies are available, such as lithium ion, and supercapacitor.
