A digital soft starter is an electrical device that is used to smoothly start and stop electric motors. It works by gradually increasing or decreasing the voltage applied to the motor, which allows it to start or stop smoothly without experiencing the high inrush currents and mechanical stress that can occur with a traditional direct-on-line (DOL) start.
Digital soft starters use microprocessors to control the voltage applied to the motor, and can be programmed to meet the specific starting and stopping requirements of the application. They can also be equipped with a variety of protective and diagnostic features, such as overload protection and fault reporting capabilities.
Digital soft starters are commonly used in a variety of applications, including pumps, fans, conveyors, and other equipment that require smooth starting and stopping. They are particularly useful in applications where the starting and stopping of the motor needs to be carefully controlled to protect the equipment or the electrical system.
