SSW-03 and SSW-04

Soft-Starters are electronic star ters designed to accelerate, decelerate and protect three-phase induction motors. The control of voltage applied to the motor, by means of thyristors firing angle variation, allows smooth starting and stopping.
With proper adjustments it is possible to optimise the motor starting torque so that starting current remains as low as possible.
WEG Soft-Starters are microprocessor based with state-of-the-art design for best starting performance of induction motors and a low cost complete solution.
The Operator Interface allows easy parameter setting for fast and troublefree star t-up.
A Pump Control feature prevents pumps running at no load and eliminates pipeline water hammer.
