-1 Scope

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

3 Impedance filter electrical characteristics

The filter shall meet the requirements given in EN 50065-4-1 and EN 50065-4-2

3.1 Overvoltage

Requirements in accordance with 7.1.5 of EN 50065-4-2:

- category III for filters used on the consumer network;

- category IV for filters used on the utility network

3.2 EMC

According to EN 50065-2-1 for consumer side in residential, commercial and light industrial environments

According to EN 50065-2-2 for consumer side in industrial environments

According to EN 50065-2-3 for utility side

4.1 Terminations

The impedance filter shall have a network port connected to the mains communication network and an equipment port connected to either a low impedance equipment or a low impedance network Implementation of impedance filter may not distinguish both ports when designed symmetrically

4.2 Operating frequency range

The operating frequency range is a (reduced) frequency range the filter is designed for

It shall be in the frequency band 3 kHz to 95 kHz for the utility network,

It shall be in the frequency band 95 kHz to 148,5 kHz for the consumer network

EN 50065-4-4:2003 6

-4.3 Impedance

At the network port when measured in the operating frequency range in accordance with 6.1 of

EN 50065-4-1, the filter shall have a minimum impedance modulus value of 10 Ω

At the equipment port there is no impedance requirement

NOTE When used in conjunction with an incoming filter type 3 (at the utility side), the combined filter shall fulfil the requirements of 4.4 of the incoming filter standard EN 50065-4-3, measured in accordance with 6.1 of EN 50065-4-1

The function of the impedance filter is only to optimise the impedance of the mains network and consequently there is no need to define a transfer function

4.5 Safety

The filter shall meet the requirements given in EN 50065-4-1 and EN 50065-4-2
