CIE Components in Electronics
Vishay Intertechnology has 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 optimised 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 O to 5.44 O, with tolerance of ± 10 %.
Customisable, the industrial power resistor can be mounted on Vishay Milwaukee frames or in NEMA 1, 2, or 3R enclosures.
