The Model 542 and 543 use Silicon Avalanche Diodes, which do
not degrade over time with transient hits, unlike metal oxide varistors.
Connecting directly to your equipment's BNC/F-Series connectors, the
Model 542/543 can handle repeated surges up to 400 amps primary
(8/20μs wave form). If the Model 542/543 receives a surge, all voltages
will be sent directly to ground through a heavy duty 6" braided metal
strap to protect your hardware. The Model 542 and 543 are housed in
ABS plastic cases and come with one male and one female BNC/F-
Series-type connectors, or two female F-Series connectors, at each
end for convenient hook-up using industry standard cables.
Warning—This product will not provide complete protection should
your equipment or building be subject to a direct lightning hit.
