This part of IEC 62040 establishes the performance and test requirements applied to movable, stationary and fixed electronic uninterruptible power systems (UPS) that

  • are supplied from AC voltage not exceeding 1 000 V,

  • deliver AC output voltage not exceeding 1 000 V,

  • incorporate an energy storage device not exceeding 1 500 V DC, and

  • have a primary function to ensure continuity of load power.

This document specifies performance and test requirements of a complete UPS and, where applicable, of individual UPS functional units. Requirements for the individual UPS functional units found in IEC publications listed in the Bibliography apply so far that they are not in contradiction with this document.

UPS are developed for a wide range of power, from less than hundred watts to several megawatts, to meet requirements for availability and quality of power to a variety of loads. Refer to Annex A and Annex B for information on typical UPS configurations and topologies.

This document also includes UPS performance and test requirements related to UPS switches that interact with UPS functional units to maintain continuity of load power.

This document does not cover

  • conventional AC and DC distribution boards and their associated switches,

  • stand-alone static transfer systems covered by IEC 62310-3,

  • rotary UPS covered by IEC 88528-11, and

  • DC UPS covered by IEC 62040-5-3.

NOTE 1 This document recognises that continuity of load power to information technology (IT) equipment represents a major UPS application. The UPS output characteristics specified in this document are therefore also aimed at ensuring compatibility with the requirements of IT equipment. This, subject any limitation stated in the manufacturer’s declaration, includes requirements for steady state and transient voltage variation as well as for the supply of both linear and non-linear load characteristics of IT equipment.

NOTE 2 Test loads specified in this document simulate both linear and non-linear load characteristics. Their use permits verification of the performance declared by the manufacturer while minimising complexity and energy consumption during the tests.

NOTE 3 This document is aimed at 50 Hz and 60 Hz applications but does not exclude other frequency applications within the domain of IEC 60196. This is subject to an agreement between manufacturer and purchaser with respect to any particular requirements arising.
