Abstract

This Uganda Standard applies to movable, stationary and fixed electronic uninterruptible power systems (UPS) that deliver single or three - phase fixed frequency a.c. output voltage not exceeding 1 000 V a.c. 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. (This Uganda Standard cancels and replaces US IEC 62040-3:1999 Uninterruptible power systems (UPS) - Part 3: Method of specifying the performance and test requirements, which has been technically revised) This standard was PUBLISHED on 2014-07-31
