Stellar Soft Starters

Stellar Soft Starters SR22 and SR33AC Motor Soft Starters | STELLAR™ SR22 Series Compact 3-Phase Soft Starters

SR22 semi-conductor solid state soft starters provide many advantages when used instead of electro-mechanical contactors to control 3-phase AC induction motors:

  • 5A to 40A rated current versions
  • 45mm and 55mm standard sizes
  • The SR22 series motor soft starters use thyristors for controlled reduced voltage motor starting and stopping
  • These low voltage soft starters then switch to internal contacts for efficient running at the rated speed

SR22 semi-conductor solid state soft starters provide many advantages when used instead of electro-mechanical contactors to control 3-phase AC induction motors.

  • The SR22 motor soft starters use thyristors for controlled reduced voltage motor starting and stopping
  • These low voltage soft starters then switch to internal contacts for efficient running at the rated speed

Applications
  • General purpose soft start applications where traditional across-the-line starting or wye-delta starting would typically be appropriate.
  • Application types include: Agitator, Air Compressor, Ball Mill, Centrifuge, Chiller, Conveyor, Crusher, Escalator, Fan (Low and High Inertia), Feeder, Grinder, Hammer Mill, Lathe Machine , Mills (Flour, etc.), Mixer (Unloaded or Loaded), Pelletizer, Plastic and Textile Machines, Press (Flywheel), Pump (Centrifugal), Pump (Positive Displacement), Rolling Mill, Saw (Band), Saw (Circular), Screen (Vibrating), Transformer, Voltage Regulator, Tumbler, Wood Chipper.

    • Extend lifespan of mechanical drive train components
    • Fluid couplings and some clutches can be eliminated
  • Electrical Advantages
    • Reduced motor starting current
    • More motors or larger motors can be started from lower-capacity power sources
    • Allows motors to be started more frequently
    • Internal mechanical contacts open and close under reduced current, increasing lifespan and reliability
  • Economic Advantages
    • Lower overall costs for new installations
    • Reduced maintenance and replacement of mechanical drive train components
    • Reduced starting current reduces electrical power costs by reducing peak demand
