Power Resistors High Current Oval Edge-wound - DOE Series

power resistors, high current, oval edge-wound

The choice when conditions demand top-notch performance, these resistors are commonly used for dynamic braking on Transit applications. Built to perform in rugged environments, they feature corrosion resistant stainless steel insulator supports, solid nickel terminals, and special electroless nickel-plated solid copper terminal supports. The resistance element is made of a stainless steel resistance alloy. Terminals are welded or silver brazed to the oval, spiral edge-wound resistance element. Toothed ceramic insulators isolate the resistance element from the center support. Ceramic end bushings insulate the center support from the mountings.
