1.Variable resistors are often called potentiometers in books and catalogues.Variable BC1 may be 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 the 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 motor by limiting the flow of current through them .
5.For non-standard technical requirements and custom special applications, please contact us to discuss the details.
