Three-phase line filter NF
Due to modern power electronics, more and more interference pulses are returned to the mains. In order to reduce or eliminate these conducted interferences (harmonics, EMC), a mains filter is additionally connected upstream of the frequency transformer. This has to be considered especially with regard to the CE mark, since the CE mark of a machine also confirms its EMC compatibility.
Chokes are vacuum impregnated with cast resin varnish to reduce humming noises and increase insulation.
We use high-quality insulation materials of the chokes for insulation class T40/F.
Connections as terminals or copper busbar depending on current.
