More fully digital soft starters have been added to the AutomationDirect drives and motor controls lineup.

STELLAR® SR35 series full-featured solid-state soft starters are available in three frame sizes to control both 1-phase and 3-phase AC induction motors with 24VDC control voltage (optional 110-230 VAC). Designed for 17-361 full-load amps at 110-240 VAC (1-phase) or 200-600 VAC (3-phase), the SR35 soft starters are fully digital and use thyristors on the A and C phases for controlled reduced voltage motor starting and stopping.

SR35 soft starters provide full motor overload protection and built-in SCR failure protection. The fully programmable units have an easy-to-navigate menu structure for quick application set up and feature integrated Modbus RTU communications as well as programmable digital inputs and relay outputs for remote control.
