Data Line Surge Protectors

Our data line surge protectors meet high demand specifications with three stage protection for maximum safety: a gas discharge tube feeds to a series resistor and a TVS (Transient Voltage Suppressor) for each supported line. IEEE 1000-4-5: 1995 andIEEE C62.41-1991 are the recognized standards for top quality, heavy duty surge protectors.
