Overvoltage protection WAVEFILTER
WAVEFILTERS for simple radio interference suppression
in the switch cabinet
The WAVEFILTER series eliminates the time-consuming need
to screw in a rectifier. The filters are simply clipped on to TS35
and connected to the device needing suppression. The twostage
WAVEFILTER with an overall width of 22.5 mm rated for
1 A, 3 A, 6 A and 10 A offers high attenuation.
WAVEFILTER with current compensating choke is ideal for
applications in controller and automation technology, e.g. for
suppressing continuous interference types such as "noise" or
“ripple” from interfering radiation from other systems, or interference
from frequency converters and switchmode power
supplies. A short low resistive mass connection is required for
the WAVEFILTER to function properly. It is advisable for all
devices to be earthed directly with the largest possible crosssection
to a central earthing point in the switch cabinet.
Interference signals
We differentiate between two types of induced transient and
continuous interference signals: symmetrical (differential mode)
and asymmetrical (common mode). The symmetrical interference
signals generate voltage between the signal lines of the
system. Asymmetrical interference voltages occur between the
signal lines and earth.
WAVEFILTER is ideal for attenuating both kinds of interference
signal. In addition, WAVEFILTER 10A also has an earthing conductor
choke. This earthing conductor choke supports both
attenuation on the earthing conductor for the filter and additional
attenuation of asymmetrical interference voltages.
