DESCRIPTION
FIGURE 2
CX 12LC CLAMPING VOLTAGE
Voltage - Volts
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-ofthe-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 grounded for those installations that
require external ground connections.

Figures 1 and 2 are photographs of digitized waveforms showing a typical transient voltage and the
clamping action of the CX12LC module. The device
was subjected to a 2000A, 8/20µs impulse waveform
in accordance with ANSI C62.36. The CX12 has an
operating frequency range up to 10MHz and the CX12LC
up to 100MHz.

Figure 3 shows a comparison of capacitance between a industrial standard device (Top Line) and the ProTek
Device CX12LC (Bottom Line). Due
to the drastic change in the capacitance of the product (Top Line), signal
distortion, loss of data or even access into the computer may be a problem.

INSTALLATION
1.21”
(30.73 mm)
The CX12 series is designed with a female BNC type connector
on both ends for easy installation. 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 protected.
Attach a ground wire between the case of the CX12 and the equipment AC power ground, or to the coax shield as required.
