Single Phase | SmoothStarters

Single Phase SmoothStarters

This product has been developed specifically to smooth start large single phase compressors and motors. It provides a dramatic reduction in the starting current while providing full start torque. It will automatically adjust itself to cover the range of 1.75 to 7 hp. It is fully self-contained in a conveniently small, double insulated and flame retardant enclosure. 


SmoothStarter is UL, CE and RoHS compliant.

Single Phase SmoothStarter

Features & Benefits

  • Rated for motors between 1.75 to 7 horse power electrical

  • Reduces locked rotor amperage (LRA)/inrush current up to 70% at start-up

  • Eliminates dimming lights

  • Reduces start-up noise

  • Avoids torque stress fracture on pipes

  • Automatic optimization of motor start-up current

  • Reduced stress and heating of compressor/motor therefore extending the life

  • Allows systems to meet certain utility requirements

  • Easy installation with supplied wiring (special wiring options available)


Motor Protection Functions

  • Protects the compressor/motor from stalling at low voltages

  • Delay function limits number of motor starts per hour

  • Thyristor protected for long life

  • No extra motor contactor needed

  • Provides motor reversal protection during short power outages

  • Internal delay timers prevents rapid cycling in fault conditions

  • Provides brownout protectionSelf-testing diagnostics
