12、bmitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 61204-7 on 2006-10-01. 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) 2007-07-01 latest date by whi

13、ch the national standards conflicting with the EN have to be withdrawn (dow) 2009-10-01 This standard does not follow the rules for structuring European Standards as given in Part 3 of the CEN/CENELEC Internal Regulations because of the varied requirements which can apply to power supplies. It assum

14、es that all power supplies are required to meet either EN 60950:2000 (IEC 60950:1999, mod.) and/or EN 60950-1:2001 (IEC 60950-1:2001, mod.). In addition power supplies may also have to meet the requirements of other standards dependent on the application. To satisfy this need it was decided that all

15、 power supplies shall meet EN 60950:2000 and/or EN 60950-1:2001 as described in the main body of this standard. The differences between these requirements and those of other standards can then be optionally applied by applying any or all of the appropriate annexes. This was done to avoid confusion.

16、The annexes of this standard are clearly described in 1.1.1. EN 61204 (IEC 61024) consists of the following parts, under the general title Low voltage power supplies, DC output: Part 1: Reserved for future use. Part 2: Performance characteristics11)Part 3: Electromagnetic compatibility (EMC) Part 4:

17、 Tests other than EMC1)Part 5: Reserved for future use. Part 6: Requirements for low-voltage power supplies of assessed performance Part 7: Safety requirements This standard should be read in conjunction with EN 60950:2000 and/or EN 60950-1:2001. It makes reference to the standard EN 60950:2000 and/

18、or EN 60950-1:2001 in the form of “clause number/RD”. In this context, “RD” means “Reference Document” i.e. EN 60950:2000 and/or EN 60950-1:2001. Unless otherwise specified, RD means that both documents apply. However, it is only necessary to apply one or other of these standards. Wherever the word

19、equipment occurs in this reference document, this means POWER SUPPLY. The annexes of EN 60950:2000 and/or EN 60950-1:2001 are also referred to by means of “RD“ where these are specific references, otherwise these annexes apply as detailed in the clauses of these standards referred to in this standar
