Soft-Starters
WEG soft-starters are fitted with micro processors and are fully digital. They are high-tech and were designed to ensure the highest performance during starts and stops of induction motors.
Description
WEG Soft-Starters are static starting switches, intended for the acceleration, deceleration and protection of three-phase, induction motors. The voltage control applied to the motor, by setting the thyristor firing angle, allows smooth starts and stops.
With proper variable settings, the torque produced is set to the requirement of the load, ensuring that the demanded current of the start is the lowest actually required.
Applications
Centrifugal pumps, alternative pumps (sanitation / irrigation / petroleum), fans, exhausts, blowers, air compressors, refrigeration (screw / piston), mixers, aerators, centrifugal machines, crushers, grinders, wood chippers, paper refiners, rotating ovens, saws and shavers (wood), mills (balls / hammer), load transportation.
