The DIGI-Start microprocessor-controlled solid-state starter provides stepless, smooth motor starting on chiller and other hvac applications, the company says. Benefits compared to conventional electromechanical units include a “soft start” to reduce stress on drive components and extended motor life via reduction of motor winding stress, says the company. A single logic control card is common for all horsepower sizes. Selectable parameters include user-selectable overloads, current limit, starting torque, and acceleration time, among others, the manufacturer says.
