DESCRIPTION
The CX12 series is a two stage, hybrid surge protector designed to protect interfacing equipment from induced lightning or switching transients. The multistage technique has proven to be the most cost effective and reliable method for protecting sensitive electronic equipment. Employing state-of-the-art avalanche junction diode technology, these devices provide superior performance for video, Ethernet, Token Ring or other LAN interface systems. They are in-line modules with easy interconnecting terminals. A completely enclosed aluminum housing provides EMC shielding to meet industry standard requirements. The enclosure has two female BNC type connections for easy installation. The case is ground for those installations that require external ground connections. www.protekdevices.com1 COAXIAL PROTECTOR 05017.R2 7/02 05017 . . . engineered solutions for the transient environment™ CX12 thru CX12LC Surgebuster® CX12 PACKAGE Figure 1 and 2 are photographs of digitized waveforms showing a typical transient voltage and the clamping action of the CX12LC module. The device was sub- jected to a 2000A, 8/20µs impulse waveform in accor- dance with ANSI C62.36. The CX12 has an operating frequency range up to 10MHz and the CX12LC up to 100MHz.

Disconnect the video or data line from the sensitive equipment. Insert the CX12 in the line near the AC power outlet of the equipment to be protected. Install a cable in between the CX12 and the equipment to be pro- tected. Attach a ground wire between the case of the CX12 and the equipment AC power ground, or to the coax shield as required.
