Product Overview

The Schneider Electric ATV71HD15N4Z is a high-performance frequency inverter from the acclaimed Altivar 71 series, specifically engineered for high-torque and constant-torque industrial applications. Rated at 15 kW (20 hp), this drive provides exceptional motor control precision for complex machinery that requires dynamic response and heavy-duty load handling. It is designed to operate on a 3-phase supply of 380V to 480V AC, featuring advanced algorithms to maintain stable speed regulation even under fluctuating voltage conditions. This "Z" variant is supplied without a graphic display terminal, making it an ideal choice for integrated control cabinets where monitoring is performed via remote HMI or centralized PLC systems.

Industrial Sector Solutions

The Altivar 71 series is the industry standard for demanding "high-end" applications where reliability and high starting torque are critical requirements.

• Hoisting and Material Handling: Providing smooth acceleration and deceleration for overhead cranes, hoists, and elevators to minimize mechanical stress and load swinging.

• Fluid Management: Controlling high-pressure pumping stations and industrial compressors where precise pressure regulation is necessary to save energy.

• Complex Process Machinery: Powering mixers, extruders, and grinders that require high starting torque and precise speed control across variable load cycles.

• Automated Production Lines: Integrating seamlessly into decentralized architectures via Modbus or optional communication cards (Ethernet, CANopen, PROFIBUS) for high-speed industrial networking.
