STC Starting Torque Controllers
Our Bulletin 154 STC™ Starting Torque Controllers provide a cost-effective, soft-starting solution for low horsepower single- and three-phase squirrel cage induction motors. Our starting torque controllers help reduce mechanical and electrical stress on motor circuits and systems by limiting voltage at start-up. This avoids the over-torque and over-current conditions that happen when across-the-line circuits are completed, like when a basic motor control contactor closes.
Features
- Offers reliable proven technology with solid state power poles
- Provides simple commissioning with only two adjustments:
- Initial Torque Setting (10...80%)
- Duration of Ramp (0.5…5 sec)
- Ideal for adding on to existing across-the-line starters
- Offers energy savings
- Less wear and tear on mechanical systems
- Offers ideal applications such as
- Basic material handling
- Fans
- Pumps
- Single phase reduced voltage starting applications
Additional Information
