What level of surge protection do Comtrol products provide?
In order to properly accommodate installation in harsh operating environments, all Comtrol DeviceMaster device servers and RocketPort multiport card serial connectivity products incorporate on-board protection from transient electrical surges produced by electrostatic discharge (ESD). This built-in protection is equivalent to a minimum of 10KV at 200 Amps for a duration of 1 nanosecond for RocketPort cards and 15KV at 200 Amps for a duration of 1 nanosecond for DeviceMaster products. Comtrol's extensive experience designing serial communication products has shown 10 - 15KV ESD protection to be the optimal price/performance level for most operating conditions. To address the needs of customers requiring installations in the most extreme conditions, Comtrol offers Surge Interfaces for card products and "special order" DeviceMaster device server models with enhanced surge protection up to 25KV at 400 Amps current for a 10-nanosecond duration.
