Rib-Wound Power Adjustable Resistors (DQS)
Adjustable Ribbon-Wound (DQS) have been a main product line at DeMint Electronics for years. Adjustable ribwound 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
