EMP proof power line filters

EMP proof power line filter for shielded rooms and anechoic chambers (type 1)

- Frequency range of 14KHz till 40 GHz, attenuation of 100dB
- Meet electrical point-of-entry requirements of MIL-STD-188-125-1 & 2 for short and intermediate pulses.

Description

A range of two- and four-line HEMP filters can be used respectively on shielded rooms or other installations for single and three phase mains supplies. All lines are individ- ually filtered and featured with necessary varistor transient suppressors at the input. This type of filter is ideally suited for EMP protection applications that need to be MIL-STD-188-125-1 conformed.

Applications

Excellent protection of 2 lines 250V (50-60Hz) and 4 lines 440/250V (50-60Hz) for supply applications in fixed installations with current ratings form 3A up to 5000A.
Protection against HEMP and lightning over voltage and electromagnetic interferences.

Advantages

Frequency range of 14KHz till 40 GHz, attenuation of 100dB
Meets electrical point-of-entry requirements of MIL-STD-188-125-1 & 2 for short and intermediate pulses.
Very high transient energy absorption capability
Utilizes self-healing feed through capacitors
Rigid steel construction for direct installation to Faraday cage.
