It primarily serves industrial pumping and ventilation systems requiring high reliability. Furthermore, the unit supports a 22 kW (30 hp) power rating at 380V to 480V. The drive effectively manages electrical loads even during voltage fluctuations in the power grid. Consequently, this module ensures smooth motor operation and extended equipment longevity.

Technical Performance Specifications

Advanced Filtering and Signal Integrity

Protection remains a key feature of the Altivar 61 series design. The ATV61HD22N4 contains a factory-installed Level 3 EMC filter to mitigate electromagnetic noise. This internal component eliminates the need for bulky external filtering hardware. Moreover, the drive complies with stringent international electromagnetic compatibility regulations. The hardware effectively shields sensitive control electronics from interference. These design choices ensure stable signal transmission across the entire automation network.

Thermal Management and Overload Capacity

Industrial environments demand hardware that can withstand extreme operational stress. This Schneider drive utilizes a high-efficiency heat sink for superior thermal dissipation. Additionally, the unit can handle significant temporary overcurrent during heavy motor startups. It supports a maximum transient current of 57.6A for one full minute. This capacity prevents nuisance tripping during peak load demands. The robust IP20 enclosure protects internal components while allowing for optimal airflow. These characteristics contribute to a highly resilient motor control solution.
