Ultra high performance filters for the highest shielding demands
The Ultra high performance filter is a superior filter housed in a three compartment casing with bolted covers and accessible terminals that achieves 100 dB insertion transmission loss at 14 kHz and above.
This series is offered as a two line filter (single phase and neutral) or as a four line filter (three phases and neutral). The two line filter can withstand up to 230 Volt, 1-150 amp and 46 kW. If you are looking for a filter that can withstand more power we have the four line filter, this filter delivers up to 400 Volt, 1-150 amp and 138 kW. The neutral line is always attenuated and all conductors are decoupled from each other. This allows the conductors to operate independently without attenuation loss.
The filter is made to withstand the harshest environment, and is very economical. Because of the custom design for your own filter, the assembly is very simple and always with very low leakage. This filter is also a stock item and therefore always available quickly.
The circuit is designed as a symmetrical double- circuit with high quality rod cores providing inductance. These cores do not saturate due to their large air gap and they are insensitive to asymmetrical load.
Foil capacitors ensure a long operating life by their self healing feature even after voltage transients. A seamless fixing of the filter casing to the shielded room is very important to ensure correct operation. The filter is housed in a casing that has a base flange which provides stable mounting and excellent earthing when bolted to the shielded room via the mounting bolts.
Please note: EMP protection is available on request.
Rated current available from 6 amp to 3000 amp in both single and three phase versions. Filters are ideally suited for applications where the very highest performance is demanded.
These protections are designed for mounting on the penetration panel or directly on the non-painted wall of the Faraday cage. Mounting terminals dependent on the amount of power. Please see Connection in the Product range table.

For a clean main supply into a shielded room, high performance filters are indispensable. Usually, these filters are directly mounted on the shielding wall. It is recommended to route filtered lines into the shielded room (Faraday cage) through the wall with an optional flexible metal conduit.
