They, in fact, protect sensitive loads against power outages as well as overvoltage and undervoltage conditions. UPS systems also suppress line transients and harmonic disturbances. Applications of UPS systems include medical facilities, lifesupport systems, data storage and computer systems, emergency equipment, telecommunications, industrial processing, and on-line management systems.
