For anechoic chamber, shielded room, cabinet, and shelter, where effective suppression of radiated and conducted emission is required.
Insertion loss: 100 dB @ 14 kHz – 40 GHz (MIL-STD-220C)
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 then our four line filter is recommended. This four line 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 operate in the harshest environment and is very economical. Because it is custom designed the assembly is very simple and operate with very low leakage. This filter is usually in stock and readily available.
The circuit is designed in a symmetrical double- circuit with high quality rod cores that provides 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 that provides stable mounting and excellent earthing when bolted to the shielded room via the mounting bolts.
Please note: EMP protection is available on request.
Advantages:
Applications:
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.
Mounting:
These protections are designed for mounting on the penetration panel or directly on the non-painted wall of the Faraday cage. Mounting terminals are dependent on the amount of power. Please see Connection in the Product range table.

General characteristics:
For 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.
