20、, DC OUTPUT PERFORMANCE CHARACTERISTICSFOREWORD1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all que
21、stions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate
22、in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the InternationalOrganization for Standardization (ISO) in accordance with conditions determined by agreement between
23、thetwo organizations.2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3) The documents produced
24、have the form of recommendations for international use and are published in the formof standards, technical specifications, technical reports or guides and they are accepted by the NationalCommittees in that sense.4) In order to promote international unification, IEC National Committees undertake to
25、 apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5) The IEC provides no marking procedure to indi
26、cate its approval and cannot be rendered responsible for anyequipment 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 subjectof patent rights. The IEC shall not be held responsible for
27、 identifying any or all such patent rights.This International Standard IEC 61204 has been prepared by subcommittee 22E: Stabilizedpower supplies, of IEC technical committee 22: Power electronics.This consolidated version of IEC 61204 is based on the first edition (1993) documents22E(CO)24 and 22E(CO
28、)26 and its amendment 1 (2001) documents 22E/77/FDIS and22E/80/RVD.It bears the edition number 1.1.A vertical line in the margin shows where the base publication has been modified byamendment 1.Annexes A to D form an integral part of this standard.The committee has decided that the contents of the b
29、ase publication and its amendment willremain unchanged until 2003. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended.SANS 61204:2007This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .61204 IE

32、tandard describes a method for specifying requirements for low-voltagepower supply devices (including switching types) providing d.c. output(s) up to 200 V d.c. at apower level of up to 30 kW, operating from a.c. or d.c. source voltages of up to 600 V.The devices are for use within class I equipment
33、 or for free-standing operation when usedwith adequate electrical and mechanical protection.This standard is intended to be used for all types of a.c. or d.c. driver power supplies with anynumber of outputs, specially produced for an unknown final application.In the case where power supplies are dev
34、eloped as a component of equipment covered byspecific product standards, these standards apply; the additional application of IEC 61204may be useful as an option, especially if the performance characteristics are not sufficientlycovered by the product standard.It permits to specify a power unit to m
35、eet a particular application by the specification ofparameters at required performance levels, to establish the essential definitions related to thistype of equipment, and to establish a selection of levels of performance. These levels arecarefully graded to enable manufacturers and users to select
36、and specify a range of powersupply devices suitable for their application.1.2 Normative referencesThe following normative documents contain provisions which, through reference in this text,constitute provisions of this International Standard. At the time of publication, the editionsindicated were va

All normative documents are subject to revision, and parties toagreements based on this International Standard are encouraged to investigate the possibilityof applying the most recent editions of the normative documents indicated below.
