Protecting susceptible electronic equipment from AC power line disturbances is a major concern for most people, whether their business environment is commercial or industrial. No matter what the ...

Lightning, inductive load switching, or capacitor bank switching may cause transient overvoltage conditions in AC line voltage applications such as white goods and appliances. Metal Oxide Varistors ...

The rate of transient occurrences varies with every power system. Recent studies show that surges of 1kV or less are common — whereas 3kV surges are rare. Protecting against more frequent (internally ...

Digital input serializers (DIS), the heart of digital input modules, must operate in harsh industrial environments. Voltage and current transients caused by electrostatic discharge, switching of ...

Industrial automation relies on programmable logic controllers (PLCs) that have been hardened against the harsh environments where they are installed. Much of the protection is mechanical to guard ...
