Electric soft starter has voltage and monitoring control

SMC-50 smart motor controller is a three-phase, fully solid-state, silicon-controlled rectifier (SCR) power structure. Addressing motor control needs of OEMs and end users, the controller uses power monitoring and diagnostics, combines monitoring and protection features, nine standard starting modes, six stopping modes, several slow-speed functions, and expandable control inputs and outputs. Rated at 200-690 Vac and with software from 90 to 520 A, it controls motor speed and torque in a range of normal-duty applications, including pumps, compressors and short conveyors, as well as in heavy-duty applications.
