10 ohm 25 watts 50mA rotary rheostat round shape

BC1 High power wirewound sliding rheostat
1. BC1 High power wirewound sliding rheostat 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).

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.
