In this standard, the following print types are used:
– requirements proper: in roman type;
– test specifications: in italic type;
– notes: in smaller roman type.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2005-06-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2011-09-01
Annex ZA has been added by CENELEC.

STEP-DOWN CONVERTORS FOR FILAMENT LAMPS –
PERFORMANCE REQUIREMENTS
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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 61047 has been prepared by subcommittee 34C: Auxiliaries for
lamps, of IEC technical committee 34: Lamps and related equipment.
This second edition of IEC 61047 cancels and replaces the first edition published in 1991, its
Amendment 1 (1996) and Amendment 2 (2001). This second edition constitutes a technical
revision. The first edition needed to be revised completely after the decision to delete all
EMC-related requirements, given that EMC varies from region to region.

INTRODUCTION
This International Standard covers performance requirements for electronic step-down
convertors for d.c. supplies up to 250 V and a.c. supplies up to 1 000 V at 50 Hz or 60 Hz,
operating with controlled voltage filament lamps at frequencies deviating from the supply
frequency.
Attention is drawn to the fact that operating frequencies below 20 kHz may cause audio noise.
NOTE CISPR requirements regarding radio interference have to be observed in some countries.
In order to obtain satisfactory performance of filament lamps and electronic convertors, it is
necessary that certain features of their designs be properly coordinated.

PERFORMANCE REQUIREMENTS
1 Scope
This International Standard specifies performance requirements for electronic step-down
convertors for use on d.c. supplies up to 250 V and a.c. supplies up to 1 000 V at 50 Hz or
60 Hz with operating frequencies deviating from the supply frequency, associated with
tungsten halogen lamps as specified in IEC 60357 and other filament lamps.
NOTE 1 The tests in this standard are type tests. Requirements for testing individual convertors during production
are not included.
NOTE 2 Requirements for convertors which incorporate means for varying the lamp power are under
consideration.
NOTE 3 It may be expected that convertors complying with this standard will ensure satisfactory operation
between 92 % and 106 % of rated supply voltage of filament lamps with rated lives greater than 200 h and rated
voltage less than 50 V.
NOTE 4 There exist regional standards regarding the regulation of mains current harmonics for end-products
such as luminaires and independent control gear. In a luminaire, the control gear is dominant in this respect.
Control gear, together with other components, should comply with these st
