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.

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.

DQS 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.
