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.

BS EN 50065-4-4:2003 频率范围为3kHz至148.5kHz的低压电气设备的信号传输.低压去耦滤波器.阻抗滤波器

This standard applies to impedance filters in a mains communication system for phase to neutral voltage not exceeding 250 V a.c. and a nominal current not exceeding 125 A, intended for household and similar fixed installation including residential, commercial and light industrial buildings. This standard also applies to "plug-in filters". These filters (see Figure 1) are used to set a suitable impedance, in the nominal frequency range of the mains signalling system, at any point of the low voltage mains network where a low impedance equipment is connected, in order to allow reliable operation of mains signalling system. These impedance filters can be used either in utility or consumer networks. They may also be used in conjunction with incoming filters and segmentation filters.

This standard applies to segmentation filters in a mains communication system used for single or multiphase installations having a phase to neutral voltage not exceeding 250 V a.c. and a nominal current not exceeding 125 A, intended for household and similar fixed installation including residential, commercial and light industrial buildings and utility networks. These filters (see Figure 1) are used to control the coupling of signals between two areas of a mains communication system. The standard defines · the minimum impedance in the relevant frequency range(s) at both ports, · the minimum attenuation of signals transmitted between port.

This standard applies to decoupling filters installed on the low voltage mains network and operating in the frequency range 3 kHz to 148,5 kHz on low voltage mains network. It does not apply to general purpose filters for EMI suppression. It does not apply to protocol dependant devices except physical layer (frequency). It does not apply to filters incorporated in household equipment for example: washing machines and coffee machines. It specifies the impedance and the transfer function definitions, requirements and test methods of the decoupling filter and some other requirements for example Voltage Drop, Leakage Current and Form Factor. The impedance and the transfer function are referred to the decoupling filter mains power ports (ref. Figure 1). The use of the decoupling filter is considered optional; additional rules or obligations may exist that are outside the scope of this standard. The safety requirements related to decoupling filters are not covered in this standard. They are covered in an other part of the EN 50065 set of standards
