12.5W Ceramic Vitreous Enameled 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.
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.
3.Any 3-terminal potentiometer can be wired as a rheostat by connecting to one end of the resistive track and to the wiper. It is best practice to connect the wiper together with the other end of the resistive track. Doing this prevents circuit interruption in case the wiper loses connection with the resistive track and also reduces noise during adjustment.
