Which statement is correct regarding the functioning of Soft Start Starters?

Soft start starters are designed to gradually ramp up the voltage supplied to an electric motor, which allows for controlled acceleration. This gradual increase in voltage helps to reduce the initial inrush current and mechanical stress on the motor and connected loads, preventing potential damage and extending the lifespan of the equipment.

By enabling controlled deceleration, soft start starters can also manage the motor's speed when shutting down, which facilitates a smoother transition and protects the system from sudden torque changes. This capability is essential in applications where sudden stops could cause mechanical failure or operational hazards.

The other statements do not accurately describe the functioning of soft start starters. For instance, they do not provide a fixed increase in voltage or allow for immediate voltage increase, as these would defeat the purpose of having a soft start feature. Additionally, stating that they do not support gradual control contradicts their fundamental operation, which is centered around providing a gradual, controlled increase in voltage and speed.
