The VP (Very High Performance) filter range are designed and tested for shielded room requirements, for attenuation from 100kHz – 10GHz at 100dB.

Shielded rooms require high levels of attenuation to ensure no conducted / radiated emissions are either imported or exported from the room. 

The filters come in 2, 3 or 4 line formats and have current ratings up to 3000Amps per phase. Transient suppression can be added as an option to the filters to give protection against induced transients from EMP sources.
The filters are housed in steel enclosures that are then painted RAL 9001 for protection.
