Watch the following videos to see how our SMC-50™ soft starters are used in the following applications:
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.
The SMC-50 soft starters deliver improved performance on high inertia loads such as rock crushers through linear acceleration technology and torque control. Limiting peak current and torque shock yields consistent starting performances. Through advanced control and monitoring uptime is maximized and the need for system maintenance is reduced.
The SMC-50 soft starters minimize starting peak current and torque shock to the system. Slow speed operation enables inspection of saw blade tracking before the motor is brought to full speed. The Smart Motor Braking option enables the system to stop in a fraction of the time of a coast stop.
The SMC-50 soft starters use linear start technology which is ideal for both high and low pressure applications such as those found in compression tanks. This soft starter also has an energy saver mode which optimizes energy usage when running lightly loaded motors.
