Powerline communication apparatus used in low voltage installations - Radio disturbance characteristics - Limits and methods of measurement - Part 3: Apparatus operating above 30 MHz FprEN 50561-3:2026

Publication date:   Jul 8, 2022

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 uses frequencies including those above 30 MHz in order to communicate.
Procedures are given for the measurement of signals generated by the equipment and limits are specified within the frequency range 9 kHz to 400 GHz. No measurement is required at frequencies where no limits are specified.
The radiated emission requirements in this standard are not intended to be applicable to the intentional transmissions from a radio-transmitter as defined by the ITU, nor to any spurious emissions related to these intentional transmissions.
NOTE2 The requirements defined in this standard effectively restrict the intended transmission frequencies to below 87,5 MHz.
