OUTPUT Part 3: Electromagnetic compatibility (EMC) FOREWORD 1) The International Electrotechnical Commission (IEC) is a wor
26、ldwide 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
27、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 sub
28、ject 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 d
29、etermined 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 Co
30、mmittees. 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 wh
31、ich 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 Public
32、ation 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 n
33、ot 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 techn
34、ical 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
35、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 subjec
36、t of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. DISCLAIMER This Redline version is not an official IEC Standard and is intended only to provide the user with an indication of what changes have been made to the previous version. Only the current ve
37、rsion of the standard is to be considered the official document. This Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. A vertical bar appears in the margin wherever a change has been made. Additions are in green text, d
38、eletions are in strikethrough red text. IEC 61204-3:2016 RLV IEC 2016 5 International Standard IEC 61204-3 has been prepared by subcommittee 22E: Stabilized power supplies, of IEC technical committee 22: Power electronic systems and equipment. IEC 61204-3 has the status of a product family standard.
39、 This third edition cancels and replaces the second edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the title has been changed by deleting the wording “DC output-“ fro
40、m the title and adding “switch mode“ in the title; b) changes in the scope: 1.1.1 Equipment covered by this document; c) update of the normative references to the latest editions or dated references; d) change of wording or/and notes regarding the requirements of CENELEC Guide 24 and IEC Guide 107;
41、e) revision of the emission limits to align with the latest editions of the applicable normative references; f) revision of the immunity requirements to align with the latest editions of the applicable normative references; g) correction of typographical errors. The text of this standard is based on
42、 the following documents: FDIS Report on voting 22E/174/FDIS 22E/176/RVD Full information on the voting for the approval of this document can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of
43、all parts of IEC 61204 series, under the general title Low-voltage power supplies, d.c. output, can be found on the IEC website. Future standards in this series will carry the new general title as cited above. Titles of existing standards in this series will be updated at the time of the next editio
44、n. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a re
45、vised edition, or amended. IMPORTANT The “colour inside” logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this publication using a colour printer. 6 IEC 61204-3:
