Protection For
Every Application
Protek has developed protection solutions for a wide range of industrial equipment/systems including test and measurement instrumentation equipment. A typical control systems application has several circuits and interfaces that are vulnerable to the effects of electrostatic discharge (ESD), electrical fast transients (EFT), secondary-lightning and other induced surges.
ProTek products provide protection from the effects of ESD/EFT/Surges as defined by IEC 61000-4-2, IEC 61000-4-4 and IEC 61000-4-5.
