TOKEN BSR, BSQ Adjustable Power Resistors Adjustable Slide W irewound Rotary Power Resistors (BSR, BSQ) One-of-A-Kind Enclosure Application to Hundreds of Enclosures Preview Following market demands, Token Electronics provides enclosures to house unlimited combinations of resistors (DR or DQ Power Series) to meet design engineers and customer requirements. Token’s high current adjustable power BSR, BSQ resistor is one-of-a-kind enclosure application to hundreds of enclosures per mount housing various resistor packages. Our engineering staff can assist the customer in meeting their unique design needs. These quality design features include all stainless steel grids and terminals, high temperature insulation, welded construction, end-frames with gussets for added mechanical strength. Slotted mounting holes for easy installation. Also accommodates a flexible range of assembly options for convenient utilization and installation. BSQ Ribwound resistors are particularly useful where high energy is to be dissipated in the lower ohmic ranges. Replacements for many standard BSR round-wire resistors are available resulting in significant savings in space and cost. The Power Adjustable BSR, and BSQ Resistor is RoHS compliant and lead free. For unusual technical requirements and custom special applications, please contact us. Features : ● Resistance Tolerance: K(±10%). ● High power and high current applications. ● Flame resistant and rugged lead free coating. ● One-of-a-kind enclosure application to fit mount housing various resistor packages. To Calculate Max. Amperes : ● Amperes = (Watts / Ohms) 1/2 Version 2010 rfq token.com.tw http://www.token.com.tw/ 01 of 04 TOKEN Construction BSR, BSQ Adjustable Power Resistors High Current Adjustable Power Resistor Construction : ● A tubular ceramic form has copper-alloy or chromium-alloy windings as a resistance element, with the mount attachment enclosures. ● These quality design features include all stainless steel grids and terminals, welded construction, high temperature insulation, end-frames with gussets for added mechanical strength. Slotted mounting holes for easy installation. ● The entire component is coated with a high-temperature non-flammable resin. ● The adjustable mechanism is a firm rotating point that slides directly on the resistance element, which allows variation of the desired resistance value. ● Also accommodates a flexible range of assembly options for convenient utilization and installation.

Power Rating of Variable Resistor: Product type Rated Wattage - The part Nunber formation of FVR, DQS, DSRA, DSRB, BSR, BSQ: 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.

Power Rating: ● Based on 25°C free air rating. The stated wattage rating applies only when the entire resistance is in the circuit. ● Setting the lug at an intermediate point reduces the wattage rating by approximately the same proportion. ● Example: If the lug is set at half resistance, the wattage is reduced by approximately one-half.
