Detailed Product Description

300Watt High Power Vitreous Ceramic Variable Wire Wound Rheostats


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.
2.Then a centered rotatingadjuster component is installed,which slides along the resistance element and varies the resistance to the desired value.
3.Single unit with multiple winding resistance values is available.
4.Different ceramic raw material & knobs,made-to-order rheostats available.
5.The product range covers a wide field, from flat,round- and wire wound resistors
6.Dimensions for reference only,consult us for more details.

 

Features: 

1.Variable resistors are often called varistors or potentiometers.Variable BCI may used as a rheostat with two connections(the wiper and just one end of the track )or as a potentiometer with all three connections in use.
2.On one resistor ,can have the different resistance requirement(flat and round wire can be in same rheostat).
3. High power rating,resistance to humidity, resistance value in great adjustable range.
4.Motor controller also use BCI series as rheostat or potentiometer to control the speed of a by limiting the flow of current through them.

5.Slide rheostats are also available and often used for education and in laboratory environments.Linear or slide types are constructed of resistive wire wound on an insulating cylinder. A sliding contact is used to increase or decrease the resistance.
6.For non-standard technical requirements and custom special applications,please contact us to discuss the details.
