Signalling on low-voltage electrical installations in the frequency range 3 kHz to 526,5 kHz - Part 1: General requirements, frequency bands and electromagnetic disturbances prEN 50065-1:2025

Scope

Modified scope of EN 50065-1 proposed in this NWI:
“This standard applies to mains communicating equipment (MCE) using signals in the frequency range 3 kHz to 526,5 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 contribute to EMC by limiting mutual influence between MCE in the same electrical installations and between different mains communicating systems (MCS) in the same environment. In addition, this standard is intended to limit interference caused by MCE signal transmission equipment to other electronic equipment.
