The HE75CX surge suppressor is a multi-stage, solid-state product designed to suppress the differential voltage impulses between the inner and outer conductors of an RF transmission line associated with natural electrical charges that exceed the device turn-on voltage. When properly installed outside to a low resistance ground, as per EIA..RS..222C standard, the HE75CX will provide a conductive path to the grounding system for said voltages up to the rated current-handling capability. The HE75CX may be ordered with BNC connectors for CCTV, Data and Audio applications or the popular ‘F’ type female connectors which make the suppressor compatible with CATV installations. Other connectors are available on request at a nominal charge.
Internally, the HE75CX utilizes a single element gas discharge tube. This tube is highly recognized as the ‘CADILLAC’ of gas tube arrestors. When an over-voltage condition is present, the gas tube appears as a short circuit. When the voltage surge is dissipated, the gas tube returns to its normal high impedance state automatically. Overvoltage transients are also addressed via silicone avalanche diodes. PTCs (resettable fuses) are also utilized within the protection scheme.
The transmission line is only one means of having impulses enter your equipment. We strongly recommend that power line protection also be installed.
Be sure to follow good grounding practices to include minimum bends and large bending radii. Make sure all grounds are tied together.
