Wire Wound Resistor (RXHG)

Product Introduction

RXHG coatings type winding resistor is a kind of power mode, the product use the wave resistance alloy in the form of side winding on the ceramic matrix The surface coating insulation resistance to high temperature coating , is conducive to heat dissipation, and is equipped with a mounting bracket, a resistor has large power , strong overload capacity resistance, convenient installation and other feature

(Product Application)

  1. As a braking resistor to protect the inverters, servos, etc .. from damage by regenerative energy of the motor
  2. As a resistive load in power electronic load tests
  3. As a sampling resister, limiting resistor, starting resistor, or protective resistor in power electronic equipment.
