EVS-EN 50065-4-3:2023

This document applies to incoming filters used to control the coupling of signals between the utility area and the consumer area, as illustrated in Figure 1.
This document defines:
- the minimum impedance in the relevant frequency band(s) at both utility port and consumer port,
- the minimum attenuation of unwanted signals transmitted from the utility side to the consumer side and vice versa.
This document applies to incoming filters designed for single or multiphase installations.
