BC1 variable ceramic wirewound slide adjustable resistor rheostat price 25w 50w 300w 1000w 50 100 500 10k 20k ohm
wirewound resistors,variable resistor,variable resistor rheostat

1.BC1 ceramic tray variable series are wound with chromium-alloy wire as a resistor element.
2.The entire component is coated non-flammable and high-temperature resin exception for the
slide contact surface.
3.After cooling and drying, insulation is applied through a high-temperature process. Installed
centered roating adjuster component slides along the resistance element to vary the
to the desired value.
4.High power rating,resistance to humidity, resistance value in great adjustable range.
5.On one resistor ,can have the different resistance requirement(flat and round wire can be in the same rheostat).
 
Features:
1.High power rating,resistance to humidity, resistance value in great adjustable range.
 
2.Widely used in educational modeling,load simulations,industiral machinery RPM adjustment,
 
voltage and current adjustment,instruments,and automated control installations, ect.
 
3.Can provide the knob with customers requirement.

Common specificaction:
25W,50W,100W,150W,300W,500W,1000W,1500W,2000W,2500W,3000W ect.
 
Specification:
1. Limit operating voltage of rheostat: 1000V: insulation voltage 2500V
2. Temperature rise of rheostat: 25-100W varieties < 300K; > 150W varieties: < 350K
3. Sliding Degree: 25-50W Varieties: 280+5 degrees; > 100W Varieties: 300+5 degrees
4. Resistance Law, Linear Deviation: During the whole journey, the resistance law changes into a linear law,
    the  linear deviation is not (+10%).
5. The rheostat control shaft should rotate for 5000 weeks in no less than 90% of the journey. There should be
     no visible damage to the rheostat.
6. The resistance of the rheostat is less than 1.5 after 6 weeks (six days) of alternating humidity and heat at
    40℃ at high temperature.
