Schneider Altistart ATS480 Soft Starter

The Schneider Electric Altivar Soft Starter ATS480 is designed for controlled starting and stopping of three-phase asynchronous motors in industrial process and infrastructure applications. With operational voltage ratings from 208 V to 690 V and current ratings from 17 A to 1,200 A, the series supports motor applications up to 900 kW. Featuring Torque Control System (TCS) technology, integrated motor protection, digital communication and flexible configuration options, the ATS480 helps reduce mechanical stress, starting current peaks and voltage drops. It is suitable for demanding industrial applications where controlled motor operation, equipment availability and process reliability are essential.

Advanced Torque Control and Soft Starting

The ATS480 uses a six-thyristor power structure and Torque Control System (TCS) algorithm to manage motor acceleration, deceleration and stopping. By controlling motor torque throughout the starting and stopping process, it helps reduce mechanical shocks, load fluctuations and fluid pressure surges in pumping systems. Its controlled starting characteristics also help limit electrical stress on the power distribution network.

Integrated Motor Protection and Digital Connectivity

The ATS480 incorporates motor thermal protection and configurable operating functions for different load requirements. Standard Modbus serial communication is available through two RJ45 ports, while optional communication modules support industrial protocols such as Modbus TCP, CANopen, PROFIBUS DP, EtherNet/IP and PROFINET. These connectivity options facilitate integration with PLCs, industrial controllers and process management systems.

Industrial Process Applications

The ATS480 is designed for demanding process and infrastructure applications, including water and wastewater treatment, oil and gas facilities, mining and minerals processing, food and beverage production, marine systems, industrial pumping stations and heavy-duty material handling equipment.
