This product video presents the Schneider Electric ATS48D47Q, a high-performance soft starter from the globally trusted Altistart 48 series—engineered to deliver intelligent motor control, enhanced protection, and seamless integration in industrial automation systems.
Rated for motor currents up to 247 A (corresponding to approximately 132 kW at 400 V in standard applications), the ATS48D47Q uses six back-to-back thyristors to precisely regulate voltage during start-up and shutdown. This minimizes mechanical shock, reduces peak current draw (typically limiting inrush to 3–4× full-load current), and extends the life of driven equipment.
Key features highlighted in the video:
Torque Control Technology: Patented adaptive torque ramp ensures smooth acceleration—even under variable load conditions
Built-in Motor & Machine Protection: Comprehensive safeguards including overload, phase loss, thermal overload, and stall protection
Integrated Keypad & Display: Onboard interface for easy parameter setting, real-time monitoring (current, voltage, status), and diagnostics
Communication Ready: Supports Modbus RTU via RS485 (standard) for integration with PLCs, SCADA, or Building Management Systems
Compact Design: Optimized footprint for panel mounting, with IP00 protection (suitable for enclosure installation)
The video demonstrates real-world operation:
→ Starting a centrifugal water pump in a municipal treatment plant—showing how soft start eliminates water hammer and reduces grid demand
→ Technician using the front-panel display to adjust ramp time from 10 to 25 seconds based on process requirements
→ Integration with a Modicon PLC via Modbus—monitoring motor status and triggering alarms on phase imbalance
→ Comparison: Direct-on-line (DOL) start vs. ATS48 soft start—highlighting 60% lower peak current and smoother torque curve
