ROUNDWIRE RESISTORS - FIXED AND ADJUSTABLE 8 WATTS TO 1150 WATTS

Milwaukee Resistor Corporation roundwire resistors are readily available in designs customized to meet your requirements.

Benefits/Features
Feature of Milwaukee Resistor Corporation roundwire resistors include:

Terminal bands are spot welded after installation on the core and resistance-alloy wire is precisely wound onto the core.
The wire is spotwelded to the terminal bands and then "locked" onto the core with a vitreous enamel, cement, or silicone coating.
Fixed, adjustable, or tapped styles are available.
Special temperature coefficients, tolerances, and non-inductive windings can be specified.
Standard lug terminals available with or without terminal hardware. Single and double quick connect terminals can be specified.
Special terminals available for unusual applications.
Mounting available with spring clips (through 1-1/8" diameter); through-bolt mounting hardware, horizontal "L" mounting brackets, and individual or multiple stacked bracket assemblies.
Hardware can be supplied mounted, as loose assemblies, or as individual parts.
Wattage ratings are based on a temperature rise of 325° C. above an ambient of 25° C.
Maximum voltage limitation is 750 V. RMS per inch of winding length.
Standard resistance tolerance is ±5%. Resistance values less than 1 ohm and adjustable resistors are ±10%. Closer tolerances are available upon request.

Applications
Typical applications for roundwire resistors in motor/motion control include areas such as dynamic braking, motor starting, speed/torque control, and plugging. Other applications include load dumping, current limiting, and voltage dropping. Roundwire resistors are commonly found in:

Overhead Cranes
Lift Trucks
Arc and Spot Welders
Processing
Battery Chargers

UPS Systems
Elevators
Machine Tools
Conveyors
Industrial Controls
