Starting Torque Limiter
Type TCI (Soft Start)
Starting Torque Limiters are designed for the soft starting of single and tree phase AC motors.
The controller allows smooth starting of all AC induction motors thus eliminating the damaging eff ects of high starting torque surges.
The TCI controller is easily installed between a standard motor starter and the motor, and features adjustable ramp-up time and initial torque.
Typical applications are conveyors, fans, compressors etc.
