High power wire wound rheostat
BC1 High power wire wound adjustable slide sliding resistance resistor rheostat
Introduction
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 rating 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).
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.
