    300W High Power Variable Resistor Ceramic Tube Wirewound Braking

    300W High Power Variable Ceramic Tube Wirewound Braking Resistors


    Structure :

    1.The high temperature resistance ceramic tube is used as the resistance matrix,is wound with chrominum alloy wire ,then coated with high temperature & non-flammable resin for protection to let resistors with better appearance and heat dissipation effect,after natural drying,baking at different temperatures before assembly.

    2.Different assembly & fitting available,different styles of mounting brackets

    3.Single unit with multi-resistance/ Multi-terminals also available;

    4.Non-inductive & variable type on requests;


    Features:

    1.These resistors are suitable as loading resistor,braking resistor,capacitor discharge,resistive load simulation,machinery,machinery and equipment higher power application.
    2.Mounting fixture is available.
    3.Resistance adjustable version :DSR series .
    4.Resistance box and load bank available with power up to 2000kW.
    5.Support precision resistance tolerance requirement.
