The  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.

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 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
