What feature of Soft Start Controllers provides gradual increase in motor voltage and current?

The gradual increase in motor voltage and current provided by Soft Start Controllers is primarily controlled by the ramp-up time feature. This feature allows the controller to gradually increase the voltage applied to the motor, which in turn results in a slow and controlled increase in current. By ramping up the voltage, the motor can gradually accelerate to its operating speed without experiencing the stress associated with an immediate application of full voltage, such as mechanical shock or excessive inrush currents. This controlled starting method minimizes wear on the motor and connected equipment while also enhancing overall operational efficiency. The ramp-up time is crucial in preventing sudden jolts that can lead to potential damage or failure in both the motor and the mechanical load it drives.
