    High Thermal Stability 5000W Ceramic Tube Resistor Suitable For Elevators


    Product Features


    High power performance: It can withstand power input up to 5KW, ensuring reliable operation under high load working conditions.


    Excellent heat dissipation performance: The ceramic tube material has good thermal conductivity, which can quickly dissipate the heat generated by the resistance, effectively reduce the working temperature and improve the service life.


    High stability:The resistance value changes very little in the process of long-term use, which ensures the stability and consistency of the circuit system.


    High temperature resistance: It can work normally at higher ambient temperature and adapt to harsh working conditions.


    Application scenarios

    5000watts Ceramic Tube Resistor, suitable for inverter, motor drive, large mechanical braking system, servo system, laser equipment and high-end scientific research instruments and other industries.
