Uninterruptible power supply (also known as the UPS from English: Uninterruptible power supply) is a device providing power to an electrical current in the event that there is a fault in the electrical network, such as a sudden interruption in the voltage due to a technical failure. These devices differ from the generator or other power devices and systems in that they contain a battery that supplies power immediately when an unexpected interruption of the supply voltage. Uninterruptible power supply can provide power for about 15 minutes depending on their technical characteristics, until he recovers the main power source or until they are safely excluded various facilities which are powered. According to the needs they satisfy, they can power from a separate computer to devices that can power entire repositories for databases or buildings.
