Part 6: Requirements for low-voltage power supplies

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61204-6 has been prepared by subcommittee 22E: Stabilized power
supplies, of IEC technical committee 22: Power electronics.
IEC 61204-6 has the status of a product standard.
The text of this standard is based on the following documents:
FDIS Report on voting
22E/76/FDIS 22E/79/RVD
Full information on the voting for the approval of this standard 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 3.

LOW-VOLTAGE POWER SUPPLIES, DC OUTPUT –
Part 6: Requirements for low-voltage power supplies
of assessed performance
1 Scope and object
This part of IEC 61204 applies to power supplies for general purpose applications. These
power supplies carry out an a.c. to d.c. conversion or a d.c. to d.c. conversion. Appropriate
provisions for safety will be found in the relevant product standards.
As far as input characteristics are concerned, this standard applies to all d.c. or a.c. source
voltages with a rated value of up to 600 V.
As far as output characteristics are concerned, this standard applies only to the supplies of d.c.
voltages of less than 200 V with a power limited to 2,5 kW; the latter power can be extended to
30 kW by taking care of the appropriate test methods.
The object of this part of IEC 61204 is to set down the requirements for the performance of
low-voltage power supply devices of assessed functionality intended for serial production. If
other performance requirements or quality assurance have been agreed by a contract, the
latter prevails.
This part of IEC 61204 is intended as a guidance for the improvement of the performance of
large series.
For performance and quality conformance inspection, the numbering of the clauses and
subclauses of this part of IEC 61204 refer, unless stated otherwise, to IEC 61204.
2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this part of IEC 61204. For dated references, subsequent amendments
to, or revisions of, any of these publications do not apply. However, parties to agreements
based on this part of IEC 61204 are encouraged to investigate the possibility of applying the
most recent editions of the normative documents indicated below. For undated references, the
latest edition of the normative document referred to applies. Members of IEC and ISO maintain
registers of currently valid International Standards.
