The SFD soft start - Features:
- Input 400-460V 3-Phase (-15% +10%) 50/60Hz +/- 2Hz
- Smooth acceleration
- Reduced starting torque decreases mechanical stress
- Suitable for all types of 3 phase induction motors
- Select from pre-programmed soft start profiles
- Kick start option for high break-away torque loads
- Soft stop to give controlled deceleration
- Over-current "shear pin" protection
- Reduction of motor starting current
- Phase loss protection at starting
