Ruggedized Industrial PC

OVERVIEW

Today’s increased reliance on very sensitive electronics makes surge protection an important topic for industries utilizing industrial PC, Panel PC and HMI operator interfaces. The Insurance Institute for Business & Home Safety study found that $26 billion dollars was lost due to non-lightning power surges. In addition, there are about 25 million lightning strikes in the US each year that cause between $650M to $1B in losses according to the Insurance Information Institute, State Farm©.

Industrial PC and HMI are a key component of many UL 508A control panel (also known as an Industrial Control Panel or ICP) deployed in the variety of applications including manufacturing, processing, data acquisition and services management. The Industrial PC has dedicated power from a power supply that may be configured with redundant sources as well as battery backup. Its failure will cause critical processes to be interrupted. The goal is to avoid this scenario by addressing vulnerabilities to transient switching surges and lightning.

Switch-Mode Power Supply

In addition, the evolution from transformer-based power supply to Switch Mode Power Supply (SMPS) increases the vulnerability of this device to electrical transients. As more solid-state components keep being added, now to remotely program and control the power supplies through RS232 or Ethernet, surge protection has become even more critical for this equipment.
