3000Watt Ceramic Wire Wound Power Adjustable Rheostats With Black Knob
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.For non-standard technical requirements and custom special
applications,please contact us to discuss the details.
6.Note:
1)Single Rheostat with Rated power 500W;
2)1000W(2pcs 500W Rheostats in series or parallel);
3)1500W(3pcs 500W Rheostats in series or parallel);
4)2000W(4pcs 500W Rheostats in series or parallel);
5)2500W(5pcs 500W Rheostats in series or parallel);
6)3000W(6pcs 500W Rheostats in series or parallel)
