An uninterruptible power supply (UPS) is an electrical device that offers emergency power in the conditions when there are sudden voltage fluctuations or power failures. The main role of any UPS is to offer temporary power when the key power source fails. Normally, a UPS is used to keep hardware such as PC, telecommunication apparatus, information centres or any other electrical equipment safe where an unforeseen power trouble could cause serious business disturbance, information loss, injuries or fatalities.
UPSs can be as small in size as a book or as big as a room. The size basically depends on how much battery backup time is necessary, and on the quantity of devices that is being protected. The UPS backup energy supply does not create any sound, unlike a generator. A UPS is a lifeboat for secure shutdowns and speedy information saving as it is best used to escape sudden power failure.
