Sommer Automatic SF150-90S Soft Starter Controller

Sommer Automatic SF150-90S Soft Starter Controller is a three-phase soft starter from Sommer’s SF150 family, engineered to start AC motors with a controlled ramp to reduce inrush current and mechanical stress during startup. As part of the SF150 line, this model provides automatic soft-start functionality for three-phase applications, with the 90S variant representing a specific model within the series. Designed for automation tasks that rely on reliable, smooth motor acceleration, the SF150-90S is suited to systems where a gradual application of motor voltage improves performance and longevity, and it integrates into control circuits that require soft-start control.
