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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 61347-2-11 has been prepared by subcommittee 34C: Auxiliaries for lamps, of IEC
technical committee 34: Lighting. It is an International Standard.
This second edition cancels and replaces the first edition published in 2001 and Amendment 1:
2017. This edition constitutes a technical revision.

– 4 – IEC 61347-2-11:2024 © IEC 2024
This edition includes the following significant technical changes with respect to the previous
edition:
a) alignment with respect to the fourth edition of IEC 61347-1:
– introduction of dated references to the fourth edition of IEC 61347-1 as appropriate;
– deletion of clauses and subclauses which are either no longer relevant or now covered
in IEC 61347-1;
b) scope extension to 1 500 V for direct current;
c) scope clarification;
d) revision of information and marking requirements;
e) addition of requirements for the determination of the output working voltage (new
Clause 17).
The text of this International Standard is based on the following documents:
Draft Report on voting
34C/1598/FDIS 34C/1601/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications.
This document is intended to be used in conjunction with IEC 61347-1:2024. Where the
requirements of any of the clauses of IEC 61347-1:2024 are referred to in this document by the
phrase "IEC 61347-1:2024, Clause n applies", this phrase is interpreted as meaning that all the
requirements of the clause in question of IEC 61347-1:2024 apply, except any which are clearly
inapplicable to the specific type of controlgear covered by this document.
NOTE In this document, the following print type is used:
– compliance statements: in italic type.
A list of all parts in the IEC 61347 series, published under the general title Controlgear for
electric light sources – Safety, can be found on the IEC website.
Future documents in this series will carry the new general title as cited above. Titles of existing
documents in this series will be updated at the time of the next edition.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn, or
• revised.
INTRODUCTION
This document specifies safety requirements for miscellaneous electronic circuits used with
luminaires. All general requirements, which apply to controlgear for electric light sources in
general, regardless of the specific type of light source in question, are contained in
IEC 61347-1. The corresponding general requirements apply to miscellaneous electronic
circuits used with luminaires by clause-wise reference in this document to any of the clauses of
IEC 61347-1, thereby specifying the extent to which such a clause is applicable and the order
in which the tests are performed.
In the same way, further documents exist specifying individual safety requirements for different
types of controlgear related to different types of electric light sources which, together with this
document, constitute the IEC 61347-2 series.
Any such parts of the IEC 61347-2 series are the leading documents for the safety assessment
of the corresponding type of controlgear; it is not IEC 61347-1.
Also, all parts of the IEC 61347-2 series do not include references to each other.
