Ametherm Receives UL Recognition for MegaSurge Series Inrush Current Limiting NTC Thermistors
Devices Are Industry's First Certified to UL 1434 for Single- and Three-Phase Input Voltages to 480 VAC
(firmenpresse) - CARSON CITY, NV -- (Marketwired) -- 08/15/13 -- Ametherm today announced that its of inrush current limiting NTC thermistors has received Underwriters Laboratories (UL) certification. In addition to recognition per UL file number E209153, the devices are the industry's only inrush current limiters certified to UL 1434 for single- and three-phase input voltages up to 480 VAC.
The thermistors released today limit inrush currents for the protection of circuits in power supplies, motor controllers, audio amplifiers, battery chargers, frequency generators, plasma cutting tools, MRI machines, and toroidal transformers. Providing a simple one-component alternative to using wirewound resistors with timers and relays, MegaSurge series devices 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 not only offer 480-VAC ratings, but 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.
Made in the USA., the UL-recognized MegaSurge devices feature resistance at 25 degrees C from 1.0 to 220 ohms, resistance at 100% of steady-state current from 0.007 to 1.50 ohms, and tolerance of 25%. The thermistors provide maximum capacitance to 1300 microfarads at 480 VAC.
Offered through Mouser, DigiKey, and Farnell, samples and production quantities of the MegaSurge series are available in three to five days. Production quantities are available with lead times of four weeks.
More information is available and samples can be requested at visit , or by calling 800-808-2434 (toll free in the U.S.) or +1 775-884-2434 from outside the U.S. and Canada.
Ametherm, headquartered in Carson City, Nev., was founded in 1994 and specializes in inrush current limiting power thermistors for circuit protection in the power market industry. Ametherm's devices are some of the highest rated in the industry and provide the widest range of output protection available. For more information, visit or call 800-808-2434.
