An uninterruptible power supply, also uninterruptible power source, UPS or battery / steering wheel backrest, is an electrical device that provides emergency power to a load when the input power source or mains fails. A UPS differs from an auxiliary or emergency power system or standby generator because it will provide near-instant protection of incoming power interruptions by supplying stored energy in batteries, supercapacitors or flywheels. The operating time on the battery of most uninterruptible power supplies is relatively short (only a few minutes), but sufficient to start a standby power supply or properly shut down the protected equipment.
A UPS is typically used to protect hardware, such as computers, data centers, telecommunications equipment, or other electrical equipment where an unexpected power outage could cause injury, fatalities, serious business interruption, or data loss. UPS units vary in size from units designed to protect a single computer without a video monitor (about 200 volts amps) to large units that power entire data centers or buildings. The 46-megawatt Battery Electric Storage System (BESS) in Fairbanks, Alaska is the 46-megawatt power supply system that feeds the entire city and surrounding rural communities during outages.
