Overview
This standard applies to movable, stationary and/or fixed electronic uninterruptible power systems (UPS) that deliver single or three-phase fixed frequency a.c. output voltage not exceeding 1 000 V and that incorporate an energy storage system, generally connected through a d.c. link. This standard is intended to specify performance and test requirements of a complete UPS and not of individual UPS functional units. The primary function of the UPS dealt with is to ensure continuity of an alternating power source. A UPS may also serve to improve the quality of the alternating power source by keeping it within specified characteristics. Different UPS have been developed over a wide range of power, from less than hundred watts to several megawatts, to meet consumer requirements for continuity and quality of power to a variety of loads. An overview of typical UPS configurations and topologies is contained in this standard. The responsible committee is K 331 "Leistungselektronik" ("Power electronic systems and equipment") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
