New Vishay Intertechnology Universal Edgewound Power Resistor Offers Current Ratings to 85 A and Power to 1600 W
Press release date: May 1, 2014
MALVERN, Pa. — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new universal edgewound power resistor. Providing a convenient drop-in replacement for competing solutions, the universal-mounted EDGU combines a high-reliability design with continuous duty operation up to 85 A and a short-time overload of 10x rated power for five seconds.
The Vishay Milwaukee EDGU features a resistance-alloy ribbon wire that is coiled on edge and supported on specially designed porcelain insulators, which provide proper turn-to-turn spacing and insulation from support bars. The device's open-coil construction allows for efficient heat dissipation and easily accommodates overloads and surges. The EDGU's terminals are welded to the resistive wire for a reliable electric connection.
With current ratings from 17.2 A to 85 A and power ratings from 400 W to 1600 W, the EDGU is optimized for precharge, discharge, dynamic braking, load testing, and heater applications in locomotives, wind turbines, and harmonic filters. The edgewound, RoHS-compliant device features a wide resistance range from 0.053 Ω to 5.44 Ω, with tolerance of 10 %. Customizable, the industrial power resistor can be mounted on Vishay Milwaukee frames or in NEMA 1, 2, or 3R enclosures.
Samples and production quantities of the EDGU are available now, with lead times of four weeks for larger orders. Pricing for U.S. delivery only starts at $20 per piece.
