TOKEN DQS Power Adjustable Resistors Power Ribbon-Wire Adjustable Resistors Low-Cost and High-Precision Power Adjustment Resistors for High Energy Dissipation Preview Adjustable Ribbon-Wound Power Resistors have been a main product line at Token Electronics for years. Ribwound adjustable resistors are particularly useful where high energy is to be dissipated in the lower ohmic ranges and high power capacity. Precision winding design, provide uniform windings to be applied extremely close to each other resulting in significantly higher resistance values. In significant savings in space and cost, Adjustable DQS Series is ideal replacements for many standard round-wire resistors. Features : ● Resistance Tolerance: K(±10%), J(±5%), H(±3%). ● Power-rib wirewound resistor with adjustable lug supplied. ● Suitable for high energy to be dissipated in the lower ohmic ranges. ● Design as heavy-duty resistors to withstand frequent start-stop cycles. ● Hollow core to permit secure fastening with spring-type clips or thru bolts with washers. ● Durability Flame resistant coating and all-welded construction. ● Terminals suitable for bolt connection or soldering. 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. ● Wattage is proportional to this adjusted resistance value. ● Adjustability is 10% to 90% of full resistance value. Options : ● Adjustable, fixed, or tapped styles are available. ● 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. ● Non-inductive Ayrton Perry windings can be specified. ● Special temperature coefficients, tolerances To Calculate Max. Amperes : ● Voltage = (Watts x Ohms) 1/2 The Power Adjustable DQS Resistor is RoHS compliant and lead free. For unusual technical requirements and custom special applications, please contact us.

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.
