Detailed Product Description

 

12.5W-3000W,Power Type Wirewound Variable Resistors ,Potentiometers

 

Structure :

1.BCI series Variable Rheostat is wound with copper or chromium-alloy wire as a resistance element. Except for the slide contact surface,the entire component is coated with a high-temperature,non-flammable resin.After cooling and drying,insulation is applied through a high-temperature process.

Then a centered rotatingadjuster component is installed,which slides along the resistance element and varies the resistance to the desired value.

2.Single unit with multiple winding resistance values is available.

3.Different ceramic raw material & knobs,made-to-order rheostats available.

 

Features:

1.BC1 series Variable Rheostats called varistors or potentiometers.

2.Used as two connections terminals of varistors or as a potentiometer with three connection terminals.When single rheostat cannot meet its power, which can be increased by connection of multiple rheostats,max up to 6 connected rheostats.
