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 (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
- Provides motor reversal protection during short power outages
- Internal delay timers prevents rapid cycling in fault conditions
- Provides brownout protection
- Self-testing diagnostics
