STC Starting Torque Controller

1-3

Features

The STC controller is a compact device with feed through wiring for

ease of installation. To set up the controller, adjust the digital rotary

switches. The initial torque value is set between 10 and 80% of

locked rotor torque. The voltage ramp time is adjustable from 0.1 to

4.5 seconds. This flexible combination enables the STC controller to

be installed in a wide variety of applications.
