Description

Brief Product Description

The Schneider Electric ATV61HD22N4 is a 22kW (30HP) high-performance variable speed drive tailored for the fluid management needs of industrial pumping and ventilation systems. It provides precise torque control and significant energy reduction for three-phase asynchronous motor applications.

Sophisticated Fluid Management and Motor Control

The Schneider Electric ATV61HD22N4 operates as a primary control hub for industrial motor systems, specifically optimized for the variable torque requirements of fans and centrifugal pumps. This 22kW unit manages three-phase asynchronous motors by adjusting frequency and voltage to match the exact demands of the process. Because it supports a broad input range from 380V to 480V AC, the drive maintains operational stability despite the voltage fluctuations often found in heavy industrial grids. Implementing this drive allows facilities to move away from inefficient mechanical throttling, resulting in immediate reductions in power consumption and mechanical wear.

Electromagnetic Integrity and System Safety

Engineers specify the ATV61HD22N4 because it integrates high-level protective features directly into the hardware architecture. A built-in Level 3 EMC filter ensures that the drive adheres to strict electromagnetic compatibility standards, effectively suppressing high-frequency interference without the need for additional external components. Furthermore, the drive’s electrical design accommodates a prospective short-circuit current of up to 22 kA. During high-demand scenarios such as motor acceleration or temporary process spikes, the unit delivers a transient current of 57.6A for up to 60 seconds, preventing nuisance tripping and maintaining continuous operation under stress.

Intuitive Configuration and Thermal Reliability

The Altivar 61 series focuses on ease of use through a dedicated graphic display terminal that simplifies the commissioning and diagnostic stages. This interface provides clear status updates and allows for rapid parameter adjustments to optimize motor performance. To ensure long-term reliability in industrial enclosures, the ATV61HD22N4 utilizes an advanced heat sink system for efficient thermal dissipation. The IP20-rated housing protects internal components from accidental contact, while the modular design allows for the addition of various fieldbus communication cards and I/O expansion modules, ensuring the drive evolves with the requirements of the automation network.
