Token (DRE) Round Edgewound Resistor is a versatile, heavy-duty unit with lightweight construction, consisting of a non-corrodible, high quality stainless steel alloy. This tough resistor is appropriate for the following applications: VFD braking, motor control, load banks and neutral grounding applications.
(DRE) resistor includes through-rods, through-bars, fixed terminals, hardware and stainless steel element. It is supported by a mounting bar which is slotted at both end. Fixed terminations are made by welding stainless steel tabs to either end of the element, or at various points for multiple connections. The ribbon-like element is coiled on edge in the form of a helix, and then spun onto a porcelain core which a threaded rod passing through the center of the ceramic core.
Token (DRE) series is also available in many mounting configurations such as stud mount version, universal edgewound, mounting bracket options of Vishay, or Ohmite. Many standard hardware options allow resistors to be purchased fully assembled, allowing easy integration into the final assembly. Assemblies are wired in parallel or in series to meet the needs of the application. Terminal blocks and thermal switches are also available.
Value-add wiring and connectors allow for a "plug-and-play" solution that easily integrates into the final assembly. Custom resistors are designed to order by our engineers and can be customized to fit unique electrical and mechanical constraints.
