    RV28 28mm plastic shaft carbon potentiometer for welding machine


    Description:


    Carbon Potentiometer is an electronic component classified as variable resistor. Carbon Potentiometer is used as voltage divider to provide variable output voltage. Carbon Potentiometers uses carbon as resistive element. There are also different types of Potentiometers like Wire Wound type and ceramic type using different materials on resistive element. Carbon Potentiometer can be classified into logarithmic type and linear type depending on the mode of operations. Carbon Potentiometers are of many types and sizes depending on resistance value, power rating and type of mounting.


    Mechanical specifications:


    Total rotation angelThe angle is measured by rotating shaft from the end of terminal R1 to the end of terminal R3.260°±10°
    Rotation torqueRotational torque when turn the shaft :without special provision,rotational speed is 60°/s in ambient temperature 5-35℃2-20mN.m
    Stop torqueThe force that shaft transfer from terminal 1 to stop point or terminal 3 to stop point after 10 seconds until be break≥5kgf.cm

    Electrical specifications:

    Total resistanceMeasurement shall be made by the resistance between terminal R1and R3.500Ω ~2MΩ
    Resistance taperResistance changesB
    Total Resistance toleranceMeasurement shall be made by the resistance tolerance between terminal R1 and R3.± 20%
    Rated powerRated power is based on continuous full load operation at the maximum voltage between terminal R1 and R3.0.5W(50 ℃)
    Residual resistanceTest residual resistance beteen terminal R1 and R2; terminal R2 and R3R≤10KΩ R0≤20Ω 10KΩ<R≤100KΩ R0≤30Ω 100KΩ<R≤250KΩ
    R0≤50Ω R≥250KΩ R0≤0.1%
    Rotation of noiseThe murmur will appear when shaft turn from terminal 1 to terminal 3 by 30 rounds/minute equably speed.≤47mV
    Voltage proofInput more then one minute voltage between terminals and shell.2000VAC
    Max. operation voltageMaximal voltage which sustained by terminal R1 and R3250VAC
    Operating temperaturePotentiometer of the performance guarantee for the use ambient temperature-30℃~70℃
    Insulation resistanceTest voltage:DC 500V,
    Test position: Between terminal and case
    200MΩ

    Others:

    Rotation lifeAfter 10,000 rotation after the test, the changes impacted no more than ± (15% R +0.5 Ω) rotational noise of not more than 100 mv
    Terminal strengthAfter welding (350℃, 3,5 seconds) after the of terminal contacts should be good, no termination loosening of
    Soldering abilityDip the terminals into tin tank at 235°C±5°C for 5±0.5 seconds, the soldering area should be more than 90%.
