Description

Brief Product Description

The Schneider Electric ATV212HD55N4 is a specialized 55kW (75HP) variable speed drive engineered to optimize fluid management and airflow in industrial HVAC systems.³ This Altivar 212 series unit prioritizes energy efficiency and building management integration for large-scale pumps, fans, and compressors.

Product Description

Specialized HVAC Process Optimization

The Schneider Electric ATV212HD55N4 serves as a high-capacity frequency inverter tailored for the specific torque requirements of centrifugal pumps and fans.⁴ By utilizing advanced motor control laws, this drive enables 55kW three-phase asynchronous motors to operate at peak efficiency, often reducing total energy expenditure by up to 70%. Its specialized design focuses on the building sector, where it manages air handling units and pumping stations with high precision.⁵ Furthermore, the drive significantly reduces mechanical stress on equipment through controlled acceleration and deceleration, extending the operational life of the entire HVAC infrastructure.⁶

Advanced Harmonic Management and Integration

Engineered to simplify installation and reduce hardware costs, the ATV212HD55N4 incorporates unique technology that minimizes low-frequency harmonics.⁷ This innovation removes the typical requirement for external line chokes or DC link reactors, thereby reducing the drive’s footprint and preventing excessive cable temperature rise.⁸ The unit also features an integrated Class C2 EMC filter, ensuring it meets strict electromagnetic compatibility standards for commercial and industrial environments.⁹ To facilitate seamless building automation, the drive supports native communication protocols, allowing it to act as a transparent node within larger control networks.¹⁰

Environmental Resilience and Connectivity

This robust drive is housed in an IP21-rated enclosure, providing essential protection for vertical wall-mount installations within electrical rooms.¹¹ Connectivity remains a core strength of the Altivar 212 series; the ATV212HD55N4 includes embedded support for Modbus, BACnet, METASYS N2, and APOGEE FLN.¹² These interfaces allow facility managers to monitor energy consumption and drive health in real-time through standard Building Management Systems (BMS). Additionally, the drive supports optional motor chokes to accommodate long cable runs, effectively neutralizing the “reflected wave” effect and protecting motor insulation in expansive facility layouts.
