The MegaSurge MS22 series Inrush Current Limiter is an economical, space-saving device designed to limit high inrush currents. Its rugged construction allows safe operation at high temperatures and continuous currents up to 50A, handling input energy of 900J. The thermistor-based limiter absorbs high surge energy upon equipment startup by offering high resistance initially, then decreasing resistance to allow steady current flow. It provides a simple, one-component alternative to wire-wound resistors with timers and relays, enhancing safety by eliminating relay failure risks. UL recognized, it can withstand steady-state currents up to 8A and input energy up to 240J. Common applications include motor drive and control, power management, audio devices, portable electronics, RF communications, and industrial systems.
