Part 3: Electromagnetic compatibility (EMC)
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. 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. 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-" from 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; SIST EN 61204-3:2018

IEC 61204-3:2016 © IEC 2016 – 5 – d) change of wording or/and notes regarding the requirements of CENELEC Guide 24 and IEC Guide 107; 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 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 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 edition. 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 revised edition, or • amended.

Part 3: Electromagnetic compatibility (EMC)
1 Scope and object 1.1 Scope 1.1.1 Equipment covered by this document This part of IEC 61204 specifies the electromagnetic compatibility (EMC) requirements for switch mode power supply (SMPS) units supplied by source voltages up to 1 000 V AC or 1 500 V DC providing AC and/or DC output(s), except inverter output(s) establishing AC mains (see exceptions under 1.1.3.) NOTE 1 This document by definition covers DC/DC converters. NOTE 2 Power supplies can provide accessory AC mains socket outlets, when such outputs are supplied from the AC mains. NOTE 3 Ringing generators used in telecoms applications are covered by this document. This product standard covers both stand alone and component power supply (PSU) units as defined in this document. It covers PSU units for use in or with IT equipment normally covered by IEC 60950-1 and/or IEC 62368-1; PSU units for use in or with measurement, control and laboratory equipment normally covered by IEC 61010-1; PSU units for use in or with medical equipment – normally covered by IEC 60601-1; PSU units for use in or with audio, video and similar electronic apparatus – normally covered by IEC 60065 and/or IEC 62368-1. It also covers DC power and distribution equipment and DC/DC converters. Where no standard exist, use of this document for other applications is not precluded. 1.1.2 Additional requirements Requirements additional to those specified in this document may be necessary for • PSUs intended for operation in special environments (for example, extremes of temperature; excessive dust, moisture or vibration; flammable gases; and corrosive or explosive atmospheres); • PSUs intended to be used in vehicles, on board ships or aircraft, or in tropical countries;
• PSUs intended for use where ingress of water is possible. NOTE Attention is drawn to the fact that authorities in some countries impose additional requirements for health, environmental and similar reasons. 1.1.3 Exclusions This document does not apply to • motor-generator sets;
• uninterruptible power supplies (UPS) to IEC 62040-1; • PSUs covered by IEC 61558-1 (i.e. power supply units incorporating safety isolating transformers providing SELV or PELV output(s) in accordance with IEC 60364-4-41) and PSUs for use with household and other consumer products, except those covered by IEC 60065 and IEC 60950-1 and/or IEC 62368-1; • transformers covered by IEC 61558-1; SIST EN 61204-3:2018

IEC 61204-3:2016 © IEC 2016 – 7 – • step-down converters covered by IEC 60146-1-1; • PSUs and converters intended for DC supplied bulb lamps, halogen lamps or LED lamps covered by CISPR 15.
1.1.4 Types of power supply
Two types of power supplies are covered by this document:
a) stand alone (or end-product) power supplies
Power supplies intended for free-standing operation (individual apparatus). This part of IEC 61204 is applicable to PSUs developed as a unit with a direct function and sold on the market as a stand alone unit. b) component power supplies These can be divided into two categories: 1) component power supplies considered as equivalent to stand alone power supplies (apparatus) This part of IEC 61204 is applicable to this category of component PSUs. These PSUs are considered to be apparatus with respect to their EMC requirements, for example those PSUs intended for use in installations or sold to the general public, cases where no further EMC tests are anticipated. This does not include PSUs sold as spares for repair which have been tested as part of an overall equipment. 2) component power supplies intended for a professional installer This part of IEC 61204 is applicable to this category of power supplies only as an aid to specify relevant EMC requirements in order that various end-product standards may be met. These are component power supplies that are intended for incorporation into a final product by a professional installer. These products may be sold to a professional installer or placed on the market for specialized distribution and use. Further EMC tests of the assembly are assumed. 1.1.5 Configurations and combinations of power supplies 1.1.5.1 Modular PSUs A PSU with a single primary circuit or module and separate output modules forming a single unit, synchronized or not, meets the requirements defined in this document as a single component or apparatus type of PSU. 1.1.5.2 Power supply systems An easily relocatable system containing several PSUs in parallel, in series or combination with a single input connection complies with this document as a single component or apparatus type of PSU. It is the responsibility of the system supplier to ensure EMC compliance with this document or with a specific EMC standard of the end product. 1.1.5.3 Power supply installations When a number of PSUs are used in an installation and are supplied by a distributed AC or DC network, then this is a power installation. This type of arrangement is not easily relocatable. Each individual PSU complies with this document and this is the responsibility of the PSU manufacturer who also provides information on the correct installation of his product. The EMC considerations of the final installation are the responsibility of the professional installer. SIST EN 61204-3:2018

– 8 – IEC 61204-3:2016 © IEC 2016 1.1.5.4 Distributed power supplies This is a power installation where the input AC or DC supply is distributed to individual power conversion units or modules which are installed locally to the circuitry to be supplied. This document applies to the individual products as appropriate. The EMC performance of the overall system or installation is the responsibility of the professional installer. 1.1.5.5 Power supplies in parallel or in series Where PSUs are sold to be connected in parallel or in series, their documentation shall include information relating to the expected EMC performance for such arrangements. 1.2 Object The object of this part of IEC 61204 is to define EMC limits and test methods for PSUs. It includes limits for electromagnetic emissions which may cause interference to other electronic equipment (e.g. radio receivers, measuring and computer devices), as well as electromagnetic immunity limits for continuous and transient conducted and radiated disturbances including electrostatic discharges. This part of IEC 61204 defines the minimum electromagnetic compatibility requirements for PSUs. To comply with this part of IEC 61204, no additional EMC tests are required or necessary beyond those stated here. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
