Power Feed Through Filters
Single line - high performance
This wide range of feed-through filters provide excellent RFI
attenuation up to GHz frequency levels. They are an economical
alternative to dedicated filter units, where multiple input or output
power lines require suppression. Particularly suitable for use in
screened rooms, high frequency welding equipment, power supplies
and telecom systems. Due to the high capacitance values of these
filters, protective measures (e.g. protective earthing) in accordance
with equipment / system regulations are required.

Mechanical Specifications
Manufacture:
metal case sealed with plastic cover;
mounted with rectangular flange (F.LL.DH)
or metric nut M32 (F.LL.DU).
Connections:
threaded bar with metric nut M6 (up to 63A),
M8 (100A), M10 (200A), M12 (300A);
Note: on screwing the cable to the filter, the lock
nut must be held in position to avoid a torque
to the threaded bar inside the filter.
