BAS EN 50065-4-3:2013

This standard applies to incoming filters used to control the coupling of signals between the utility area and the consumer area (see Figure 1). The standard 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, • the transmission characteristics: - operating frequency domain for both utility side and consumer side, - attenuation between the utility side and the consumer side and vice versa, - impedance at the utility side and at the consumer side. This standard applies to incoming filters designed for and used in single or multiphase installations.
