The Stellar line of soft starters now includes the SR55 series of solid-state soft starters to control three-phase ac induction motors. Designed to withstand up to 477 FLA at 200-480 Vac, the soft starters are available in three frame sizes. They are fully digital; provide full motor overload protection; and use thyristors in all three motor phases for controlled, reduced-voltage motor starting and stopping. The series features 24-Vdc, 110- or 230-Vac-selectable control voltage, as well as separately adjustable motor start and stop times. These units are equipped with a touchscreen, built-in SCR failure protection and full data logging.
