Soft start, motor soft starters

Power arrange: 90KW-630KW

Key Parameters

FWI-SS3 3-phase AC460V 60Hz by-pass contactor

1. Our Intelligent motor soft starter can adapt the rapid development of electric power automation technology which has higher requirements.

2. Soft starter detects the feedback voltage of the motor, and achieve closed loop control, make sure the motor succeed to start-up under different conditions..

3. Reduce the starting stress of the motor, help the motor and equipment to achieve the maximum service life.

Features

1. Fast installation and set-up. Only 3 settings are required (FLC, ramp-up and ramp-down)

2. Compact dimensions. 12 - 45Arms in 45mm wide housing, 55 - 100Arms in 75mm wide housing.

3. Reduction of voltage drops at the start

4. Supply voltage from 220 to 1140 VAC

5. Great mechanical stresses reduction on the couplings and transmission devices (gear boxes, pulleys, gears, belts, etc.) during the start

6. Integrated protection. Diagnostic functions provide additional protection. TR-2E is also equipped with an overload protection

7. Torque control during ramp-down. Smoother deceleration of the load.

8. Programmable delay ramp-up mode and programmable interlock control.

9. No phase sequence requirements for input power supply.

10. adjusting ramp-up time and ramp-down time is available.

11. Multiple protection as: motor overload, overcurrent, phase imbalance, phase sequence, excess start time, motor thermistor, supply fault, shorted SCR. etc.

Typical Applications:

packaging machinery, water pumps, sliding doors, belt drives, conveyors, conveying machinery, door drives of passenger and goods lifts, limitation of starting current for transformers, wind turbines, compressors
