Schneider Electric Altivar 212 ATV212HD55N4 55kW Variable Speed Drive

The Schneider Electric ATV212HD55N4 is a 55kW (75HP) Variable Speed Drive engineered for high-efficiency HVAC applications. It features built-in BACnet/Modbus support, integrated EMC filtering, and energy-saving technology that reduces power consumption by up to 70% in building management systems.

Operational Overview and HVAC Specialization

The Schneider Electric ATV212HD55N4 functions as a dedicated frequency inverter within the Altivar 212 series, specifically optimized for heating, ventilation, and air conditioning (HVAC) systems. This high-capacity drive manages three-phase asynchronous motors with a substantial power rating of 55 kW (75 HP). By focusing on centrifugal load profiles, the unit provides superior fluid management while significantly lowering operational costs.

Engineered to operate within a 380V to 480V AC range, this drive enhances building automation efficiency. It integrates a specialized design that eliminates the requirement for line chokes or additional DC chokes, which simplifies installation and reduces the overall footprint within electrical rooms. Consequently, facility managers can achieve streamlined motor control without sacrificing electrical stability.

Key Technical Characteristics and Performance

Exceptional Energy Savings: The drive utilizes advanced energy-optimization algorithms to reduce power consumption by as much as 70% when compared to traditional motor starters.
