18、reword This European Standard was prepared by SC 205A, Mains communicating systems, of Technical Committee CENELEC TC 205, Home and Building Electronic Systems (HBES). This European Standard has been prepared under a mandate given to CENELEC by the European Commission and covers the essential requir
19、ements of the Low Voltage Directive 73/23/EEC. The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC as EN 50065-4-2 on 2000-11-01. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an id

24、 decoupling filters Impedance filter Part 4-5 Low voltage decoupling filters Segmentation filter Part 4-6 Low voltage decoupling filters Phase coupler Part 7 Equipment impedance #This safety standard EN 50065-4-2 has no frequency dependent content. It was originally conceived as a safety document wi
25、thin the EN 50065 set of standards, which have a frequency of 3 kHz to 148,5 kHz. When the scope of SC 205A was extended to 30 MHz, SC 205A agreed that the scope of the published safety standard, Part 4-2 “Low voltage decoupling filters Safety requirements“ should be amended to include the band 1,6
26、MHz to 30 MHz in order to cover the additional set of standards for 1,6 MHz to 30 MHz. This required no technical changes to the body of the document. In addition, it was agreed that Part 4-7 “Portable low voltage decoupling filters Safety requirements“ should also cover both frequency ranges. For t
27、his reason the title of this part of EN 50065 covers the extended frequency ranges 3 kHz to 148,5 kHz and 1,6 MHz to 30 MHz.$ - 3 - EN 50065-4-2:2001 Foreword to amendment A1 This amendment was prepared by SC 205A, Mains communicating systems, of Technical Committee CENELEC TC 205, Home and Building
