- Provides a simple one-component alternative to using wirewound resistors with timers and relays, MegaSurge series inrush current limiting NTC thermistors reduce costs and greatly simplify designs.
- In addition, they increase safety by eliminating the fire hazard associated with failed relays.
- While traditional thermistors are only certified for input voltages from 85 VAC to 265 VAC, UL-recognized MegaSurge devices are certified for single- and three-phase input voltages up to 480 VAC.
- In addition, they have the ability to withstand high steady-state currents to 36 A and up to 300 J of input energy.
- These specifications are the highest of any single-solution inrush current limiting device on the market.
Target Applications: Inrush Current Protection of Power Supplies, Motor Controllers, Audio Amplifiers, Battery Chargers, Frequency Generators, Plasma Cutting Tools, MRI Machines and, Toroidal Transformers.
