The line of adjustable-speed drives provide accurate and repeatable speed settings and can be used as a prime mover connected to a motor, or as a secondary drive.

When used as a secondary drive, the drive becomes a variable-ratio device. It permits slow or fast, small or large speed changes. As a prime mover, the drive acts as a variable-speed device and accepts 0 to 2,000-rpm input speeds. Output speed changes can be made quickly and easily, whether the machine is running or not. The drives provide speed control for inputs from ¼ to 1½-hp applications with output torque ratings from 12 through 200 lb-in. Output speed is set with a control-lever adjustment. An optional screw control (Micro Dial) feature provides an accurate reference for applications that require repeatability, letting users more accurately set and repeat various settings.

Design features of the drive include easy mounting in most positions; handles any input, such as chain, belt, and couplings; easy to install – no wiring needed; and is factory lubricated.
