Part 2-10: Particular requirements for electronic invertors
and convertors for high-frequency operation of cold start
tubular discharge lamps (neon tubes)



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.

INTRODUCTION
This part of IEC 61347, and the parts which make up IEC 61347-2, in referring to any of the
clauses of IEC 61347-1, specify the extent to which such a clause is applicable and the order
in which the tests are to be performed; they also include additional requirements, as
necessary. All parts which make up IEC 61347-2 are self-contained and, therefore, do not
include references to each other.
Where the requirements of any of the clauses of IEC 61347-1 are referred to in this standard
by the phrase ”The requirements of clause n of IEC 61347-1 apply”, this phrase is interpreted
as meaning that all requirements of the clause in question of part 1 apply, except any which
are clearly inapplicable to the specific type of lamp controlgear covered by this particular part
of IEC 61347-2.

LAMP CONTROLGEAR –

Part 2-10: Particular requirements for electronic invertors
and convertors for high-frequency operation of cold start
tubular discharge lamps (neon tubes)



1 Scope
This part of IEC 61347 specifies particular requirements for electronic invertors and
convertors for high-frequency operation of tubular cold-cathode discharge lamps used in
signs and luminous discharge tube installations and operating with an output voltage
exceeding 1 000 V but not exceeding 10 000 V for direct connection to supply voltages not
exceeding 1 000 V at 50 Hz or 60 Hz or 1 000 V d.c.
NOTE 1 In Japan, the output voltage of 15 000 V is acceptable.
The requirements for two types of invertors and convertors, types A and B, are specified as
follows:
– Type A unit: an invertor or convertor operating within the frequency range 20 kHz to
50 kHz, and having an output voltage (between terminals) not exceeding 5 000 V peak, a
maximum output current limited to 35 mA (r.m.s.) and 50 mA (peak value). The supply
voltage does not exceed 250 V at 50 Hz or 60 Hz or 250 V d.c.
NOTE 2 The output current of a type A unit may be considered as not presenting an electric shock hazard due to
the limits on the current and frequency range.
NOTE 3 In Japan, the output voltage of 15 000 V is acceptable.
– Type B unit: an invertor or convertor having a no-load output voltage not exceeding
5 000 V to earth or 10 000 V between terminals, operating within the frequency range
10 kHz to 100 kHz with a maximum output current limited to 200 mA (r.m.s.) and 400 mA
(peak value).
NOTE 4 Type B units require additional protection in the output circuit.
NOTE 5 In Japan, a type B unit exceeding 50 mA and/or the secondary grounded is not acceptable.
In order to check the safety of invertors or convertors, it is necessary to check their
performance. However, since no standardization of the characteristics of neon tubes exists,
reference loads are specified in this standard to ensure reproducible test results.
The rated maximum operating temperature of the winding, t , is not applicable to this
w
standard.
