Power Line Filters
Power Line Filters are low-pass EMI/RFI devices for power conductors that enter or leave shielded rooms, SCIFs, server rooms, and test facilities. Published high-attenuation and low-leakage series cover 15/30 A through 400 A and both AC and DC systems. Depending on series, insertion loss reaches 100 dB from 14 kHz or 150 kHz through 18 GHz. Welded and soldered steel enclosures preserve shielding at the power penetration.
