DANSK DS/EN 50065-4-3 PDF

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 attenuatiuon 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 consumer side. This standard applies to incoming filters designed for and used in single or multiphase installations.
