Vishay: New EDGS Stud-Mount Edgewound Power Resistor

Vishay Intertechnology, Inc. introduces a new stud-mount version of its edgewound power resistor. Providing a convenient drop-in replacement for competing solutions, the EDGS 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 EDGS- Serie combines its high current and power ratings with a high-reliability design. The resistor 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 threaded stud mounts. The device’s open-coil construction allows for efficient heat dissipation and easily accommodates overloads and surges. The EDGS’s terminals are welded to the resistive wire for a reliable electrical connection. Customizable, the industrial power resistor can be mounted on supplied Vishay Milwaukee brackets or in IP-rated enclosures.

The device is also available in a universal-mounted version: the EDGU.
