DR Round-Wirewound Power Resistors
Round-Wirewound
Power Resistors
The Best Cost-Effective Power Resistor
for High Energy Applications (DR)
Preview
Features:
● Fixed, adjustable, or tapped styles are available.
● Special terminals are available for unusual applications.
● Special temperature coefficients, tolerances,
and resistance value can be specified.
● Ayrton Perry type non-inductive winding formats
are available. See DRS Series when requied.
● Standard resistance tolerance is ±5% and ±10%.
Closer tolerances are available upon request.
● Standard lug terminals available with or without
terminal hardware.
● Single and double quick connect terminals
can be specified.
● The wire is spot welded to the terminal bands and then “fastened” onto the core with a silicone, cement,
or vitreous enamel coating.
Round Wire-wound Power Resistor Construction:
● A tubular ceramic has two terminals and is wound with copper roundwire or chromium alloy roundwire
to provide the resistance.
● Coated with non-flammable resin in high temperature. Insulation is applied through a high-temperature
process and the mounts are attached.
● Due to Token excellent winding technolgy applied , many taps can be added, impedance is low and the
shape can be altered to produce many types.
Applications:
● Ideal for educational modeling applications, load testing, industrial machinery, electric power
distribution, instruments, automation control installations, etc.
● Typical applications for roundwire DR series in motor/motion control include areas such as dynamic
braking, motor starting, speed/torque control, industrial machinery, electric power distribution, and plugging.
● Other applications include load dumping, current limiting, elevators, UPS systems, lift trucks, and
voltage dropping.
The DR Series is RoHS compliant and lead free. Order individual replacement units, entire grids with various
mounting configurations, or custom specifications, please contact us to discuss the details.
