Description

Brief Product Description

The Schneider Electric ATV71HD22N4Z is a high-performance 22 kW Altivar 71 variable speed drive designed for constant torque applications in complex industrial machinery. It delivers precise motor control and advanced thermal management for heavy-duty three-phase asynchronous motors.

​Product Description

Advanced Motor Control for High-Torque Loads

The Schneider Electric ATV71HD22N4Z belongs to the Altivar 71 family, a series specifically optimized for high-power applications requiring exceptional torque and speed precision. This 22 kW (30 HP) drive excels in managing constant torque loads, making it an ideal choice for elevators, hoists, and heavy-duty conveyors. By utilizing sophisticated vector control algorithms, the drive ensures smooth acceleration and deceleration while maintaining high torque at low speeds. It operates across a three-phase voltage range of 380V to 480V, effectively accommodating global power standards and voltage fluctuations commonly found in industrial grids.

Thermal Efficiency and Long-Distance Installation

Efficiency drives the design of the ATV71HD22N4Z, which features a specialized heat sink to facilitate rapid heat dissipation during continuous high-load operations. This thermal management system allows the drive to maintain peak performance even in demanding environments. Furthermore, the unit offers impressive installation flexibility by supporting long motor cable runs. Specifically, engineers can deploy shielded cables up to 100 meters or unshielded cables up to 200 meters without compromising signal integrity. This extended range simplifies the floor layout of large manufacturing facilities by allowing centralized drive placement away from the motor.

Industrial Durability and Integration

Robustness defines the physical construction of this Altivar 71 unit. The drive includes an integrated Electromagnetic Compatibility (EMC) filter to minimize electrical noise and protect sensitive surrounding electronics. While this specific “Z” variant ships without a remote graphic display terminal, it provides comprehensive communication options for remote monitoring and PLC integration. The enclosure shields critical internal components from airborne contaminants, ensuring a long service life in sectors such as mining, water treatment, and material handling. Additionally, the drive actively optimizes energy consumption, which reduces the total cost of ownership over the product’s operational lifespan.
