EN 50065-1:1991

EN 50065-1:1991 is a standard published by CLC. Its full title is "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". This standard covers: 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 supply system 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 signal modulation methods nor the coding methods nor functional features (except those for the prevention of mutual interference) . Environmental requirements and tests are not included. Note: In most countries the transmission of information is subject to regulation. 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 supply system where this would not otherwise be allowed.
