Variable Power Resistors - BSR, BSQ Series

variable power resistors

BSR, BSQ Series
A tubular ceramic form has copper-alloy or chromium-alloy windings as a resistance element, with the mount attachment method the same as the other described. Except for the sliding contact surface on the windings, the entire component is coated with a high-temperature non-flammable resin. The adjustment mechanism is a rotating point that slides directly on the resistance element, which allows variation of the resistance value (See the specifications of the DR series and VR series for exact features). Suitable for education, testing, load simulations, automation control installations, etc. For custom specifications, please contact us to discuss the details.

Remark:

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.

If you need currunt constant type or special specifications, please feel free to cntact us.
