Single Phase Soft Starters

This product has been developed specifically to soft start large single phase compressors and motors. It provides a dramatic reduction in the starting current but still provides 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. 

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 light flicker
• 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.

Motor Protection Functions

• Protects the compressor/motor from stalling at low voltages
• Delay function limits number of motor starts per hour
• Provides motor reversal protection during short power outages
• Internal delay timers prevents rapid cycling in fault conditions
• Provides brownout protection
• Self-testing diagnostics
