International Standards and Conformity Assessment for all electrical, electronic and related technologies



Reference EN 50065-1:2011
Title Signalling on low-voltage electrical installations in the frequency range 3 kHz to 148,5 kHz - Part 1: General requirements, frequency bands and electromagnetic disturbances
Project Number 22484
Abstract/Scope This standard applies to electrical equipment using signals in the frequency range 3 kHz to 148,5 kHz to transmit information on low voltage electrical systems, either on the public electricity distribution network or within installations in consumers’ premises. It specifies the frequency bands allocated to the different applications, limits for the terminal output voltage in the operating band and limits for conducted and radiated disturbance. It also gives the methods of measurement. It does not specify the modulation methods, the coding methods or functional features (except those for the prevention of mutual interference). Environmental requirements and tests are not included. NOTE 1 Compliance with this standard does not imply permission to establish communication with locations outside the consumer’s installation or with other consumers through the public electricity distribution network where this would not otherwise be allowed. The object of the standard is to limit mutual influence between transmission equipment in electrical installations and between such equipment and other equipment. In addition this standard is intended to limit interference caused by signal transmission equipment to sensitive electronic equipment. However, complete freedom from such interference cannot be assured. NOTE 2 Designers should consider signalling systems in conformance with this standard when determining immunity for electrical equipment.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
