POWER RESISTORS

Oval Edgewound High Current Power Resistors

DOE

When lower resistance with higher power capacity is required, Use Token China's Edge-wound Power High Current design.


Oval Edgewound High Current Power Resistors - DOE Series

Designed in both Edge-wound and Round Wire patterns, these DOE resistors can handle 550 to 3250 Watts of power. Specify Token China's Edgewound design for very low resistance and high power capacity.


Built to perform in rugged environments, DOE resistors are constructed of a heavy resistance alloy mounted on ceramic insulators, solid nickel terminals, and supported by special electroless nickel-plated solid copper terminals.


These heavily plated and supports prevent oxidation at high operating temperatures and corrosion.


Applications:

  • Motor Starting, Plugging, Dynamic Braking, Load Banks, Power Load Measurements
  • Automation Control Installations, Electric Distribution, Instrumentation, Power Industrial Machinery

Wattage Rating:

  • Can be found from Amperes2 * Ohms

Resistance Tolerance:

  • Nominal Tolerance K (±10%)

The power DOE resistor is lead-free and RoHS compliant. Please contact us for details with your specific needs.
