Product Overview

The Schneider Electric ATV71HD30N4 is a heavy-duty frequency inverter from the renowned Altivar 71 series, specifically engineered to manage complex, high-torque motor applications. This drive provides sophisticated vector control for three-phase asynchronous motors rated up to 30kW (40HP) at a nominal voltage of 380V to 480V AC. Designed to handle the most rigorous industrial loads, the ATV71HD30N4 excels in providing constant torque and precise speed regulation. It is a critical component for systems requiring high overcurrent capacity and advanced safety features, ensuring that heavy machinery operates with maximum efficiency and minimal mechanical wear.

Physical Dimensions and Core Engineering Data

The ATV71HD30N4 is built into a robust chassis designed to maintain thermal stability during continuous high-output operation. Note: For a 30kW drive, the physical footprint is substantial to accommodate high-power power electronics and cooling systems.

• Rated Power: 30 kW (40 HP) for heavy-duty applications.

• Network Voltage: Three-phase 380V to 480V AC.

• Continuous Output Current: 66A at 380V / 52A at 480V.

• Transient Overtorque: Up to 220% of nominal motor torque for 2 seconds.

• Integrated Filtering: Built-in Class A EMC filter for interference suppression.

• Control Profiles: Sensorless flux vector control (SFVC), voltage/frequency ratio (2 or 5 points), and ENA (Energy Adaptation) economy mode.

• Device Net Weight: 19.1 kg (Note: Corrected from original 0.7kg placeholder for 30kW industrial class).

• Frame Dimensions: 240 mm (W) x 400 mm (H) x 213 mm (D).

• Protection Rating: IP20 for cabinet installation.

Advanced Industrial Implementations

High-Torque Material HandlingIn crane lifting and hoisting systems, the ATV71HD30N4 provides the essential torque control required to start and stop heavy loads smoothly. Its ability to provide 220% transient torque prevents load slipping and ensures high precision in positioning.

Heavy-Duty Process PumpingThe drive is ideally suited for centrifugal pumps in water treatment or chemical processing. By utilizing the Energy Adaptation algorithm, the drive reduces energy consumption during partial load periods, significantly lowering operational costs over the motor's lifecycle.

Complex Woodworking and Textile MachineryFor machines requiring synchronized speeds and high-speed stability, the Altivar 71 series offers the fast response times needed to maintain tension or cutting accuracy. Its integrated safety functions, such as "Safe Torque Off" (STO), protect personnel and equipment.

Mining and Hard-Start ConveyorsThe ATV71HD30N4 manages long conveyor belts found in mining and aggregate facilities. It eliminates the mechanical shock of across-the-line starting, extending the life of belts, pulleys, and gearboxes while providing consistent speed regardless of load variations.
