AutomationDirect’s line of Stellar® 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), SR55 full-featured solid-state soft starters are available in three frame sizes and provide many advantages over electromechanical contactors. SR55 soft starters are fully digital, provide full motor overload protection, and use thyristors in all three motor phases for controlled, reduced voltage motor starting and stopping.
SR55 soft starters are used in general purpose soft start motor control applications where traditional across-the-line starting or wye-delta starting would typically be appropriate and are ideal in applications requiring lower inrush currents. SR55s also have a built-in internal bypass and patented iERS (intelligent Energy Recovery System) that reduces energy costs when used on lightly loaded and oversized motors.
The SR55 series features 24VDC, 110 or 230 VAC selectable control voltage, as well as easily and separately adjustable motor start and stop times. These fully programmable units are equipped with a touchscreen with an easy-to-navigate menu structure, a quick Automatic Application Setup feature, built-in SCR failure protection, and full data logging (fault records, motor current, operational status, etc.) SR55 soft starters also feature integrated Modbus RTU, or optional Modbus TCP or Ethernet/IP communication, as well as programmable analog I/O, digital inputs and relay outputs for remote control.
The IP20-rated Stellar SR55 soft starters are panel-mountable with optional finger guards (for frame sizes 1 and 2 soft starters) and are suitable for a variety of motor loads. Stellar SR55 soft starters can be used for motor reversing, with external contactors, and can be connected “in-delta”, allowing for use of a smaller soft starter (no iERS optimizing with in-delta connections).
Backed with a two-year warranty, the SR55 series soft starters are UL listed, CE, REACH, and RoHS approved. Size 1 starters, with 17A to 96A current ratings, start at $975.00; Size 2 starters, with 124A to 180A current ratings, start at $1,605.00, and size 3 starters with 242A to 477A current ratings start at $2,784.00.
