PolyPhaser dc Blocked

IS-NEMP SERIES
NUCLEAR EMP COAXIAL SURGE PROTECTOR

APPLICATION:

Military, government (FEMA and NCA), protection of emergency radio communications equipment.

	Weatherize using WK-1
	Employs UL497B listed gas tube
	Patented technology
	Ultra-fast response
	Low throughput energy
	High surge current handling
	Aluminum enclosure
	18-8 stainless steel hardware
	Bulkhead mountable up to ]/4" thick panels (flange mount adapter)
	N silver shell and gold center pin
	Highest pulse attenuation (30.1 4dB for IS-NEMP-CO) of all models tested by NCS (TIB 85-10 document)
	Mounts outside screen room penetration panel or equipment housing for best skin effect and pulse attenuation
	EMI/RFI weather washer for low impedance no drip penetration
