TOKEN DRS Power Adjustable Resistors Power Round-Wire Adjustable Resistors Adjustable Resistor for Applications Requiring Settings at Different Resistance Values Preview Choose Token’s Power DRS adjustable resistor for applications requiring settings at different resistance values. These wirewound resistors are equipped with an adjustable lug, making them ideal for adjusting circuits, obtaining unique resistance values and setting equipment to meet various line voltages. DRS resistors feature a hollow core to permit secure fastening with thru bolts with washers or spring-type clips. They also offer the durability of lead free vitreous enamel, or silicone coating and all-welded construction. The Power Adjustable DRS Resistor is RoHS compliant and lead free. For non-standard technical requirements and custom special applications, please contact us. To Calculate Max. Amperes : ● Voltage = (Watts x Ohms) 1/2 Power Rating : ● Adjustability is 10% to 90% of full resistance value. ● Wattage is proportional to this adjusted resistance value. ● Example: If the lug is set at half resistance, the wattage is reduced by approximately one-half. ● Setting the lug at an intermediate point reduces the wattage rating by approximately the same proportion. ● Based on 25°C free air rating. The stated wattage rating applies only when the entire resistance is in the circuit. Features : ● Adjustable lug supplied. ● High wattage applications. ● Flame resistant and rugged lead coating. ● Resistance Tolerance: J(±5%), K(±10%). ● Terminals suitable for soldering or bolt connection. Options : ● Special temperature coefficients, tolerances ● Adjustable, fixed, or tapped styles are available. ● Non-inductive Ayrton Perry windings can be specified. ● Special terminals available for non-standard applications. ● Single and double quick connect terminals can be specified. ● Standard lug terminals available with or without terminal hardware.

DQS - Application Notes 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 04 of 05 - Rated Wattage - Resistance Value (Ω) http://www.token.com.tw/ - Resistance Tolerance rfq token.com.tw Version 2010 TOKEN DRS Power Adjustable Resistors 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. Notes: ● Adjustability is 10% to 90% of full resistance value. ● Wattage is proportional to this adjusted resistance value. 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.
