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.
