Detailed Product Description

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.
