FWI-SS3 Soft Starter

Soft Starter to protect the electric motor

FWI-SS3    3-phase AC460V 60Hz without built-in by-pass contactor

• Our Intelligent motor soft starter can adapt the rapid development of electric power automation technology which has higher requirements.
• 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..
• Reduce the starting stress of the motor, help the motor and equipment to achieve the maximum service life.

Features

• Fast installation and set-up. Only 3 settings are required (FLC, ramp-up and ramp-down)
• Compact dimensions. 12 - 45Arms in 45mm wide housing, 55 - 100Arms in 75mm wide housing.
• Reduction of voltage drops at the start
• Supply voltage from 220 to 1140 VAC
• Great mechanical stresses reduction on the couplings and transmission devices (gear boxes, pulleys, gears, belts, etc.) during the start
• Integrated protection. Diagnostic functions provide additional protection. TR-2E is also equipped with an overload protection
• Torque  control  during  ramp-down. Smoother deceleration of the load.
• Programmable delay ramp-up mode and programmable interlock control.
• No phase sequence requirements for input power supply.
• adjusting ramp-up time and ramp-down time is available.
• 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
