Oval Flat-Wirewound Power Resistors

ZR

When limited space is a consideration Choose Token China's "Thin" stackable ZR power resistors.


Design engineers can now benefit from Tokenchina's new technologies capable of oval flat-wirewound power resistors.


Built to perform in rugged environments, flat wirewound ZR series is constructed of a thin oval cross section and flat mounting brackets allow stacking into compact units. The aluminum mounting brackets extend through the resistor core and equalize heat distribution while conducting heat directly into the mounting surface.


Supporting a flexible range of applications, the power oval ZR series is ideally suited for applications where space is limited and the mounting surface can be utilized for heat dissipation purposes, easy to utilize and install.

Power Oval Flat-Wirewound Resistors - ZR Series

Applications:

  • Power Load Testing, Automation Control Installations, Dynamic Braking, Load Banks, Plugging
  • Power Distribution, Instrumentation, Power Industrial Machinery

Non-Inductive:

  • Ayrton Perry type non-inductive winding is available. When required add "N" to the part number.

Wattage Rating:

  • Can be found from Volts2 / Ohms

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