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.
