Schneider Electric ATS48C59Q Altistart 48 Soft Starter

Product Overview

The Schneider Electric ATS48C59Q Altistart 48 Soft Starter is a high-performance electronic motor soft starter engineered for three-phase asynchronous motors, designed in compliance with IEC 60947-4-2 and Schneider motor control specifications. Built for smooth torque-controlled motor acceleration, gentle motor deceleration & comprehensive motor overload protection, this soft starter adopts patented TCS torque control technology and withstands cabinet temperature variation and mechanical vibration in heavy-duty industrial environments. It delivers stable continuous operation and reduces mechanical shock and current surge for large pumps, fans, compressors and marine motor systems.

Featuring six anti-parallel thyristor power circuit, built-in Modbus communication interface & integrated LCD local operation panel. Both cabinet base mounting and panel installation are supported, adapting to limited installation space inside low voltage control cabinets and motor control centers. The modular assembly allows separate replacement of control board without full motor system shutdown, greatly reducing equipment downtime for service. Equipped with phase loss detection, locked rotor protection & real-time operating data logging, mature hardware structure prevents motor damage and guarantees reliable motor start-stop during continuous duty.

For dependable smooth torque-controlled motor acceleration, gentle motor deceleration & comprehensive motor overload protection, this ATS48C59Q soft starter regulates motor torque instead of simple voltage ramp, realizing linear start and stop independent of motor load. Reliable smooth torque-controlled motor acceleration, gentle motor deceleration & comprehensive motor overload protection, premium industrial grade electronic components provide excellent resistance to thermal stress, extending service life in harsh industrial working environments. Practical phase loss detection, locked rotor protection & real-time operating data logging, precise torque control lowers mechanical impact during long-hour operation, protecting pipelines, gearboxes and driven equipment under variable load conditions.

During continuous smooth torque-controlled motor acceleration, gentle motor deceleration & comprehensive motor overload protection, this Altistart 48 soft starter is widely used in water treatment, oil & gas, power plant and marine motor control projects, fully compatible with Schneider EcoStruxure automation platform. Stable smooth torque-controlled motor acceleration, gentle motor deceleration & comprehensive motor overload protection, mature Schneider Altistart soft start technology with easy spare parts replacement and convenient after-sales maintenance. Robust phase loss detection, locked rotor protection & real-time operating data logging, simplifies control cabinet layout and reduces installation workload for industrial motor retrofitting and motor control system overhaul projects.
