The SMC-50 soft starters use new soft start technology to provide torque and speed control for starting centrifugal pumps and high-inertia loads. Through proprietary sensorless speed sensing and motor control algorithms, the SMC-50 soft starter can deliver even smoother pump starts and stops than was possible with previous pump-control methods.

By using six back-to-back silicon-controlled rectifiers (SCRs) (two per phase), the SMC-50 soft starter provides controlled acceleration, operation/run, and deceleration of standard asynchronous induction motors. Power structures are available with …

As shown in Figure 15, the SMC-50 contains 12 control terminals and is equipped as standard with two digital 24V DC on/off inputs and two relay outputs for auxillary control function.

Use the SMC Estimation Wizard and SMC Thermal Estimation Wizard to confirm that the SMC controller selection meets the application requirements. See SMC-3, SMC Flex, and SMC-50 Technical Data, publication 150-TD009 for more information.

Our enclosed SMC-3, SMC Flex, and SMC-50 soft starters are available as non-combination, combination fused disconnect, or combination circuit breaker starters. Enclosed soft starters may be fully customized with a wide variety of factory-installed options and are pre-engineered for quick factory lead times.

CENTERLINE 1500 medium voltage soft starters feature a MV SMC™-50 smart motor controller and a range of starting and stopping modes for industrial applications. The MV SMC-50 smart motor controller is a microprocessor-based design that …

Refer to technote 459611 - SMC-50 soft starter User manuals, Wiring Diagrams and other literature for user manual, quick start guide and instruction sheets.

The SMC-50TM solid-state smart motor controller combines all of the features of a starter in one package; it can provide control of three-phase control of resistive loads (using firmware v. 5.01 and later) while simultaneously providing protection such as current limit, overload, no load, and other features you typically expect with motor contro...
