DESCRIPTION
FIGURE 2
CX 12LC CLAMPING VOLTAGE
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 connec-
tions for easy installation. The case is grounded for those installations that
require external ground connections.

Figures 1 and 2 are photographs of digitized wave-
forms 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.
