Control line lightning and surge protectors
L-com Inc. has added a series of single stage ac/dc control line lightning and surge protectors. The new products protect 8 individual single ended ac or dc control lines using grounding lugs to provide tie points for earth ground. They all feature removable screw terminal strips for easy installation.
Lightning and surge protectors are necessary for many wired connectivity lines. They protect sensitive electrical equipment on either end of a cable from transient voltage, or spikes, which may be caused by lightning strikes and other factors. AC and DC control lines are used in a range of applications and are commonly found on measurement and control equipment, computers, motor controllers and industrial automation equipment.
The ac protectors feature Metal Oxide Varistors (MOV), while the dc protectors feature uni-polar Transient Voltage Suppression (TVS) Diodes rated at 1500 Watts.
