Advantages AE Extreme Line Filter:
“Normal” line filters work from about 100 kHz – 100 MHz with a peak suppression in the area between 1 – 10 MHz. All these filters is load dependent: A 10 Amps filter will have a different filter curve when loaded with 1 Amp instead of 10 Amp. This filter is based on the principle of an artificial V-line, which is normally used in EMC-testing. This filter has a frequency range of 9 kHz – 1 GHz with noise reduction better than 40 dB and it is load independent.
Using air-coils with a wire diameter of 6 mm no way would limit the dynamics. Technically it´s constructed for 50 Amps per phase. The Phases are decoupled from each other better than 80 dB, due to a comported HF-shielded case.
The filter can be connected to a single phase, dual phase or three-phase output. It always delivers three decoupled outputs.
The huge air coils are inductive components without soft magnetic core. Air coils have compared to soft-core coils with relatively small inductances. The absence of a magnetic core makes the magnetisation characteristic curve linear. The coil is critical, because there is no magnetic saturation. Only Siemens in Germany can manufacture it with such big size.
