Soft-starters are drives dedicated to the smooth acceleration and deceleration of three-phase electric motors, by controlling the voltage applied to the motor. With proper adjustment of the variables, the torque produced is adjusted to the load requirement, thus ensuring that the requested current is the minimum required for starting. The SSW900 is a soft-starter with three-phase motor control, built-in by-pass and torque control. Intended to drive motors from 10 to 1.400 A.
