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 startup. 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.
Overview
- 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 direct-on-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
The previous generation Starting Torque Controller is discontinued and no longer available for sale. This current Bulletin 154 Starting Torque Controller is an excellent replacement for the previous product.
