Applications
Watch the following videos to see how our SMC-50™ soft starters are used in the following applications.
Water Pump
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.
Compression Tank
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.
