Uninterruptible power systems (UPS) - Part 5-3: d.c. output UPS - Performance and test requirements (IEC 62040-5-3:2016)

This part of IEC 62040 establishes the performance and test requirements applied to
movable, stationary and fixed electronic DC uninterruptible power systems (DC UPS) that
– are supplied from an AC voltage source not exceeding 1 000 V,
– deliver a DC output voltage not exceeding 1 500 V,
– incorporate an energy storage device, and
– have a primary function to ensure continuity of DC power to loads.
This document specifies performance and test requirements of a complete DC UPS and not of
individual DC UPS functional units. The individual DC 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 document.
DC UPSs have been developed over a wide range of power, from less than a hundred watts
to 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 DC UPS configurations and topologies.
This document also includes DC UPS performance and test requirements related to
interrupters, isolating switches, and tie switches, if any, which are integral to the DC UPS.
These components interact with other functional units of the DC UPS to maintain continuity
of load power.
This document does not cover
– conventional AC input distribution boards and their associated switches,
– conventional DC distribution boards and their associated switches,
– conventional AC UPSs covered by IEC 62040-3,
– low-voltage DC power supply devices covered by a specific product standard, for example
IEC 61204, and those covered by a specific product standard, for example ITU
communication standards, and
– systems wherein the output voltage is derived from a rotating machine.
NOTE 1 This document recognises that power availability to information technology (IT) equipment represents a
major UPS application. The DC UPS output characteristics specified in this document are therefore also aimed at
ensuring compatibility with the requirements of IT equipment. This, subject to 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 resistive and constant power load characteristics of IT equipment.
NOTE 2 Test loads specified in this document simulate both resistive and constant power 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.

Alimentations sans interruption (ASI) - Partie 5-3: ASI à tension de sortie continue - Performances et exigences d'essai (IEC 62040-5-3:2016)

L'IEC 62040-5-3:2016 établit les exigences de performance et d'essai appliquées aux alimentations sans interruption à tension continue (ASI à tension continue) électroniques mobiles, semi-fixes ou installées à poste fixe qui
- sont alimentées par une source de tension en courant alternatif n'excédant pas 1 000 V,
- délivrent une tension de sortie continue n'excédant pas 1 500 V,
- intègrent un dispositif de stockage d'énergie, et
- possèdent une fonction primaire visant à maintenir la continuité de l'alimentation en courant continu des charges. Le présent document spécifie les exigences de performances et d'essais relatives à une ASI à tension continue complète et non aux unités fonctionnelles d'ASI à tension continue individuelles.

Sistemi za neprekinjeno napajanje (UPS) - 5-3. del: Enosmerni izhod UPS - Lastnosti in preskusne zahteve (IEC 62040-5-3:2016)

Ta del standarda IEC 62040 določa lastnosti in preskusne zahteve, ki se uporabljajo za premične, stacionarne in fiksne elektronske sisteme za neprekinjeno napajanje z enosmernim tokom (DC UPS), ki
– se napajajo iz vira izmeničnega toka z napetostjo, ki ne presega 1000 V,
– dobavljajo enosmerni tok z napetostjo, ki ne presega 1500 V,
– vključujejo napravo za shranjevanje električne energije in
– vključujejo glavno funkcijo zagotavljanja neprekinjene dobave enosmernega toka porabnikom.
Ta dokument določa lastnosti in preskusne zahteve celotnega sistema za neprekinjeno napajanje z enosmernim tokom in ne posameznih funkcijskih enot sistema. Posamezne funkcijske enote sistema za neprekinjeno napajanje z enosmernim tokom so obravnavane v publikacijah IEC, ki so navedene v bibliografiji in se uporabljajo, če niso v nasprotju s tem dokumentom.
Sistemi za neprekinjeno napajanje z enosmernim tokom so bili razviti za širok razpon moči, od manj kot sto vatov do nekaj megavatov, da lahko izpolnjujejo zahteve glede razpoložljivosti in kakovosti energije za različne porabnike.
Glej dodatka A in B za informacije o tipičnih konfiguracijah in topologijah sistema za neprekinjeno napajanje z enosmernim tokom.
Ta dokument vsebuje tudi lastnosti in preskusne zahteve za morebitne odklopnike, ločilna stikala in povezovalna stikala, ki so sestavni del sistema za neprekinjeno napajanje z enosmernim tokom. Te komponente vzajemno delujejo z drugimi funkcijskimi enotami sistema za neprekinjeno napajanje z enosmernim tokom za vzdrževanje neprekinjenega napajanja.
Ta dokument ne zajema:
– konvencionalnih izmeničnih vhodnih razdelilnikov in z njimi povezanih stikal,
– konvencionalnih enosmernih razdelilnikov in z njimi povezanih stikal,
– konvencionalnih sistemov za neprekinjeno napajanje z izmeničnim tokom, ki so zajeti v standardu IEC 62040-3,
– nizkonapetostnih naprav za napajanje z enosmernim tokom, ki so zajete v določenih standardih za izdelek, na primer IEC 61204, in tistih, ki so zajete v določenih standardih za izdelek, na primer komunikacijskih standardih ITU, ter
– sistemov, ki izhodno napetost pridobivajo iz rotacijske naprave.
OPOMBA 1: Ta dokument navaja, da je zagotavljanje razpoložljivosti energije za opremo informacijske tehnologije (IT) eden od glavnih načinov uporabe sistemov za neprekinjeno napajanje. Namen lastnosti izhoda sistema za neprekinjeno napajanje z enosmernim tokom, ki so navedene v tem dokumentu, je zato tudi zagotavljanje združljivosti z zahtevami opreme IT. To ob upoštevanju kakršnih koli omejitev, navedenih v deklaraciji proizvajalca, vključuje zahteve za spreminjanje napetosti v stacionarnem stanju in prehodne napetosti ter za lastnosti uporne obremenitve in obremenitve pri konstanti moči opreme IT.
OPOMBA 2: Preskusne obremenitve, ki so navedene v tem dokumentu, simulirajo lastnosti uporne obremenitve in obremenitve pri konstantni moči.
Njihova uporaba je predpisana z namenom preverjanja zasnove in delovanja, ki ju navede proizvajalec, ter zmanjševanja kompleksnosti in porabe energije med preskusi.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
