Wideband Line Filter for Active Line Modules
3.7.4.1
Wideband Line Filters for Active Line Modules are mainly effective in the frequency range
from 150 kHz to 30 MHz; this is the range relevant to ensure compliance with the appropriate
standard. Wideband Line Filters can also effectively limit low-frequency line harmonics of
2 kHz and above; this protects additional loads connected to the same supply system
against disturbances and damage. As a result, these line filters have an extended function
range, with which a certain degree of independence can be achieved regarding the machine
installation location with generally unknown line supply parameters (e.g. line impedance).
Wideband line filters must always be used in conjunction with a line reactor for Active Line
Modules. Active Interface Modules cannot be used.
