LOW-VOLTAGE POWER SUPPLIES, DC OUTPUT –
Part 6: Requirements for low-voltage power supplies
of assessed performance
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.

3 Procedure and classification
The requirements of this standard apply to
– either the manufacturer's standard power supplies meeting the requirements of the detail
specifications,
– or to specific, custom-made power supplies.
The procedure includes the following three provisions:
– the manufacturer's quality control, methods and manufacturing procedures, shall be
certified to the ISO 9000 series or equivalent;
– initial product compliance with the performance requirements;
– periodic quality conformance assessment.
This standard covers the following types of power supplies:
– type A: modules for printed circuits;
– type B: power supplies up to 250 W excluding modules for printed circuits;
– type C: power supplies greater than 250 W and up to 1 kW;
– type D: power supplies greater than 1 kW.
4 Initial product compliance and tests
The tests are specified in clause 6.
All the tests shall be mandatory if the manufacturer/(user) confirms/(specifies) the presence of
the feature or parameter for each model family of the power supply.
The manufacturer has to keep the records of the test results for 10 years after delivery of the
last unit.
The recommended number of specimens for the manufacturer's standard power supplies
depends on the type:
– type A: 10 specimens
– type B: 5 specimens
– type C: 3 specimens
– type D: 2 specimens
For custom-made power supplies, the number of specimens should be discussed in the
particular contract between the manufacturer/user.

5 Periodic quality conformance assessment
For quality conformance assessment, the periodic conformance inspection for the power supply
devices described in the detail specification includes the tests described in 5.1 and 5.2 below.
5.1 Batch tests
These tests are conducted by the manufacturer during normal production in order to make sure
that the device produced meets the conditions defined in the production specifications. Normal
production tests are those tests carried out by the manufacturer on all units to verify the power
supply functionality.
If the tests of the normal production testing are not covered in clause 7, they are to be carried
out in addition.
The manufacturer has to keep the records of the test results for 10
