AC Power Port Protection

Problem: Voltage and Current Transients

Electrical equipment can be put at risk from high voltage or power transients on the AC inputs due to lightning strikes or power station load switching transients and from the resulting surge currents.
 

Solution: LVR + ROV

Overvoltage and overcurrent protection are often viewed as unrelated conditions. With PolySwitch LVR devices and Raychem Metal Oxide Varistors (ROV), Tyco Electronics offers designers a complete solution that helps enhance product protection and reliability.
