(Main)Uninterruptible power systems (UPS) - Part 3: Method of specifying the performance and test requirements (IEC 62040-3:2021)
Uninterruptible power systems (UPS) - Part 3: Method of specifying the performance and test requirements (IEC 62040-3:2021)
IEC 62040-3:2011 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. The individual UPS functional units are dealt with in IEC publications referred to in the bibliography that apply so far that they are not in contradiction with this standard. The primary function of the UPS covered by this standard is to ensure continuity of an a.c. power source. The UPS may also serve to improve the quality of the power source by keeping it within specified characteristics. UPS have been developed over 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 Annexes A and B for information on typical UPS configurations and topologies. This standard also covers UPS test and performance when power switches form integral part of a UPS and are associated with its output. Included are interrupters, bypass switches, isolating switches, and tie switches. These switches interact with other functional units of the UPS to maintain continuity of load power. This standard does not cover:
- conventional a.c. input and output distribution boards or d.c. boards and their associated switches (e.g. switches for batteries, rectifier output or inverter input);
- stand-alone static transfer systems covered by IEC 62310-3;
- systems wherein the output voltage is derived from a rotating machine.
NOTE 1 This standard recognises that power availability to information technology (IT) equipment represents a major UPS application. The UPS output characteristics specified in this standard 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 standard simulate both linear and non-linear load characteristics. Their use is prescribed with the objective of verifying design and performance, as declared by the manufacturer, and also of minimising any complexity and energy consumption during the tests.
NOTE 3 This standard 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 purchase in respect to any particular requirements arising.
NOTE 4 Single phase and three-phase voltage UPS covered by this standard include without limitation UPS supplying single-phase, two-wire; single-phase, three-wire; two-phase, three-wire, three-phase, three-wire and three-phase, four-wire loads.
This second edition cancels and replaces first edition published in 1999 and constitutes a technical revision. The significant technical changes are:
- reference test load - definition and application revised (3.3.5 and 6.1.1.3);
- test schedule - presented as a single table grouped by revised type and routine tests (see 6.1.6, Table 3);
- dynamic output voltage performance characteristics - guidance to measure - addition (Annex H);
- UPS efficiency - requirements and methods of measure - addition (Annexes I and J);
- functional availa

Alimentations sans interruption (ASI) - Partie 3: Méthode de spécification des performances et exigences d'essais (IEC 62040-3:2021)
La CEI 62040-3:2011 s'applique aux systèmes d'alimentation sans interruption (ASI) électroniques mobiles, immobiles et fixes, qui délivrent une tension de sortie alternative à fréquence fixe mono- ou triphasée ne dépassant pas 1 000 V en courant alternatif et qui possèdent un moyen d'accumulation d'énergie généralement connecté via une liaison à courant continu. La présente norme vise à spécifier les performances et les exigences d'essai d'une ASI complète et non des unités fonctionnelles d'ASI individuelles. Les unités fonctionnelles d'ASI individuelles sont traitées dans des publications CEI auxquelles il est fait référence dans la bibliographie, lesquelles s'appliquent dans la mesure où elles ne sont pas en contradiction avec la présente norme. La fonction essentielle de l'alimentation sans interruption (ASI) couverte par la présente norme est d'assurer la permanence d'une source d'alimentation alternative. L'alimentation sans interruption peut aussi servir à améliorer la qualité de la source d'alimentation en la maintenant dans les limites des caractéristiques spécifiées. Toutes sortes d'alimentations sans interruption ont été développées pour satisfaire aux exigences par rapport à la permanence et à la qualité de l'alimentation de différents types de charges dans une large gamme de puissance de moins de cent watts à plusieurs mégawatts. Se reporter aux Annexes A et B pour avoir des informations sur les configurations et topologies types des ASI. Cette norme concerne également les essais et performances d'ASI quand des interrupteurs de puissance font partie intégrante d'une ASI et sont associés à sa sortie. Elle inclut les interrupteurs, les interrupteurs de bypass, les interrupteurs d'isolement et les interrupteurs de liaison. Ces interrupteurs réagissent avec d'autres unités fonctionnelles de l'ASI pour maintenir la continuité de l'alimentation de la charge. La présente norme ne couvre pas:
- les tableaux de distribution conventionnels à entrée et sortie alternatives ou les tableaux en continu et leurs interrupteurs associés (par exemple les interrupteurs pour batteries, pour la sortie du redresseur ou pour l'entrée de l'onduleur);
- les systèmes de transfert statique autonomes couverts par la CEI 62310-3;
- les systèmes dont la tension de sortie est dérivée d'une machine tournante.
NOTE 1 Cette norme reconnaît que la disponibilité de l'alimentation pour les matériels de traitement de l'information (IT) représente une application majeure des ASI. Les caractéristiques de sortie de l'ASI spécifiées dans la présente norme ont donc également pour but de garantir la compatibilité avec les exigences des matériels d'IT. Celle-ci, soumise à toute limitation indiquée dans la déclaration du fabricant, comporte des exigences relatives aux variations de tension en régime établi et transitoire ainsi qu'à l'alimentation des caractéristiques de charge à la fois linéaires et non linéaires des matériels d'IT.
NOTE 2 Les charges d'essai spécifiées dans la présente norme simulent les caractéristiques de charge à la fois linéaires et non linéaires. Leur usage est prescrit avec pour objectif de vérifier la conception et la performance déclarées par le fabricant, ainsi que de limiter toute complexité et consommation d'énergie pendant les essais.
NOTE 3 La présente norme vise les applications à 50 Hz et à 60 Hz mais n'exclut pas les applications à d'autres fréquences dans le domaine de la CEI 60196. Cela est soumis à un accord entre le fabricant et l'achete

92 Part 3: Method of specifying the performance and test requirements
93 FOREWORD
94 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
95 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
96 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
97 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
98 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
99 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
100 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
101 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
102 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
103 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
104 consensus of opinion on the relevant subjects since each technical committee has representation from all
105 interested IEC National Committees.
106 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
107 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
108 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
109 misinterpretation by any end user.
110 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
111 transparently to the maximum extent possible in their national and regional publications. Any divergence between
112 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
113 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
114 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
115 services carried out by independent certification bodies.
116 6) All users should ensure that they have the latest edition of this publication.
117 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
118 members of its technical committees and IEC National Committees for any personal injury, property damage or
119 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
120 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
121 Publications.
122 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
123 indispensable for the correct application of this publication.
124 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
125 rights. IEC shall not be held responsible for identifying any or all such patent rights.
126 International Standard IEC 62040-3 was prepared by subcommittee 22H: Uninterruptible power
127 systems (UPS) of IEC technical committee 22: Power electronic systems and equipment.
128 This third edition cancels and replaces second edition published in 2011 and constitutes a
129 technical revision. The significant technical changes are:
130 − Environmental conditions aligned with IEC 62040-1 Ed2:2017 (UPS safety
131 requirements);
132 − Compliance requirements included in all sub-clauses referenced in Table 5 UPS
133 test schedule;
134 − Non-linear step load removed from 6.4 Type tests in consistency with
135 requirements for switch mode power supplies incorporating inrush current controls.
136 This resulted in the performance classification coding being shortened from 8 to 7
137 characters. See 5.3.4;
138 − Free-fall test aligned with ISO 4180. See 6.5.1.3;
139 − Multiple normal mode UPS performance classification introduced;

oSIST prEN IEC 62040-3:2020
62040-3/Ed3/CDV IEC (E) – 5 – 22H/254/CDV
141 − Non-linear load requirements relaxed in Annex E in consistency with requirements
142 for switch mode power supplies complying with the applicable limits for harmonic
143 current in IEC 61000-3-2 and IEC 61000-3-12; and
144 − Minimum UPS efficiency values referenced in Annex I became normative and
145 based on active output power rating and utilisation of weighting factors rather than
146 on allowances related to isolation transformers, input harmonic current filtering and
147 to input voltages.

174 Part 3: Method of specifying the performance and test requirements
175 1 Scope
176 This part of IEC 62040 establishes the performance and test requirements applied to movable,
177 stationary and fixed electronic uninterruptible power systems (UPS) that
178
179 − are supplied from AC voltage not exceeding 1 000 V;
180 − deliver AC output voltage not exceeding 1 000 V;
181 − incorporate an energy storage device not exceeding 1 500 V DC; and
182 − have a primary function to ensure continuity of load power.
183
184 This document specifies performance and test requirements of a complete UPS and, where applicable,
185 of individual UPS functional units. Requirements for the individual UPS functional units found in IEC
186 publications listed in the bibliography apply so far that they are not in contradiction with this document.
187 UPS are developed for a wide range of power, from less than hundred watts to several
188 megawatts, to meet requirements for availability and quality of power to a variety of loads.
189 Refer to Annexes A and B for information on typical UPS configurations and topologies.
190 This document also includes UPS performance and test requirements related to UPS switches that
191 interact with other functional units of the UPS to maintain continuity of load power.
192 This standard does not cover
193 – conventional AC and DC distribution boards and their associated switches;
194 – stand-alone static transfer systems covered by IEC 62310-3;
195 – rotary UPS covered by IEC 88528-11; and;
196 – DC UPS covered by IEC 62040-5-3.
197 NOTE 1 This standard recognises that continuity of load power to information technology (IT) equipment
198 represents a major UPS application. The UPS output characteristics specified in this standard are therefore also
199 aimed at ensuring compatibility with the requirements of IT equipment. This, subject any limitation stated in the
200 manufacturer’s declaration, includes requirements for steady state and transient voltage variation as well as for the
201 supply of both linear and non-linear load characteristics of IT equipment.
202 NOTE 2 Test loads specified in this standard simulate both linear and non-linear load characteristics. Their use
203 is prescribed with the objective of verifying the performance declared by the manufacturer, and of minimising any
204 complexity and energy consumption during the tests.
205 NOTE 3 This standard is aimed at 50 Hz and 60 Hz applications but does not exclude other frequency applications
206 within the domain of IEC 60196. This is subject to an agreement between manufacturer and purchaser with respect
207 to any particular requirements arising.
