The Schneider Electric Altistart 48 Soft Starter, model ATS48C17Q, is a heavy-duty soft starter and soft stopping controller designed for three-phase asynchronous motors. It provides torque-controlled start and stop functions to reduce mechanical stress, improve the lifetime of electrical and mechanical components, and enhance process reliability in industrial applications. This unit is suitable for use in pumps, fans, compressors, conveyors, and general industrial machinery where controlled starting and stopping of large motors is required. The soft starter also integrates motor and starter protection functions and supports communication with control systems for monitoring and automation
