Determination of End resistance value of FVR, DQS, DSRA, DSRB, BSR, BSQ:
Resistance Range means you can choose one maximum resistance value (End resistance value) at one of FVR, DQS, DSRA, DSRB, BSR, BSQ VR (Variable Resistor) type.
After End Resistance Value confirmed, the minimum resistance (start resistance value) will be determined by depending on resistance of wire and wirewound type.
Power Rating of Variable Resistor:
The part Nunber formation of FVR, DQS, DSRA, DSRB, BSR, BSQ:
Product type
- Rated Wattage
- Resistance Value (Ω)
- Resistance Tolerance
Product type means one of FVR, DQS, DSRA, DSRB, BSR, BSQ.
Rated Wattage means power rating at End Resistance Value.
Resistance Value (Ω) means maximum resistance value (End resistance value).
Resistance Tolerance means precision range of End Resistance Value.
1. Power Rating of VR (Variable Resistor) is determined by the maximum resistance value (End resistance value).
2. Resistance and Power Rating should be decreased while you are adjusting the screw.

A
C-shaped ceramic 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. Then, a centered rotating adjuster component is installed,
which slides along the resistance element and varies the resistance
to the desired value. The scope of the application includes educational
modeling, load simulations, industrial machinery RPM adjustment, voltage
and current adjustment, instruments, and automated control installations.
For custom specifications, please contact us to discuss the details.
