100Watt Ceramic Tray Adjustable Wirewound Power Rheostats /Potentiometers
Structure :
1.A rheostat is a variable resistor which is used to control current,able to vary the resistance in a circuit without interruption.
2.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.
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 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.ZENITHSUN rheostats can be equipped with a mechanical stop to limit the minimum or maximum resistance. For special applications they can also be built with tapered windings.
