High Current Oval Edge-wound Power Resistors
(DOE)(DOE) The Choice When Conditions Demand Top-Notch Performance Preview
Token DOE Series are commonly used as a dynamic braking resistor 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.
