Product Overview

The Schneider Electric ATV212HD37N4 is a high-efficiency Altivar 212 variable speed drive tailored specifically for intelligent fluid management and HVAC systems in commercial and industrial infrastructures. This 37 kW (50 HP) inverter is engineered to regulate three-phase asynchronous motors within a 380V to 480V AC voltage range. By prioritizing eco-design principles, this drive facilitates a significant reduction in energy consumption—often up to 70%—when compared to traditional fixed-speed motor starters. Its specialized architecture eliminates the need for bulky external line chokes or DC reactors for harmonic mitigation, significantly reducing the footprint and complexity of the electrical installation while maintaining high power quality.
