FprEN 50561-1:2026

Powerline communication apparatus used in low voltage installations - Radio disturbance characteristics - Limits and methods of measurement - Part 1: Apparatus for in-home use

Publication date:   Oct 30, 2026

Scope

This part of EN 50561 specifies limits and methods of measurement of radio disturbance characteristics for in-home PLC communication apparatus that use the low-voltage power installation as the transmission medium by intentionally injecting a signal EXCLUSIVELY between two Phase (L) conductors or between one Phase (L) and Neutral (N) conductors of the low-voltage power installation.
NOTE 1 This part of EN 50561 does NOT apply to in-home PLC communication apparatus that use the low-voltage power installation as the transmission medium by intentionally injecting a signal between any Phase (L) or Neutral (N) conductors and the ground or earth (E) conductor of the low-voltage power installation.
This part of EN 50561 applies to equipment that communicate over this medium in the frequency range 1,606 5 MHz to 30 MHz.
NOTE 2 Similar equipment that communicate outside this frequency range is covered by EN 50561-3.
Procedures are given for the measurement of signals generated by the equipment and limits are specified for the frequency range 9 kHz to 400 GHz. No measurement is required at frequencies where no limit is specified.
