The Schneider Variable Speed Drive ATV71HC25N4 is a robust 37 kW (50 hp) variable speed drive from the Altivar 212 series, specifically engineered for HVAC applications involving pumps and fans. Operating on a three-phase power supply within a wide voltage range of 323V to 528V and frequency tolerance of 47.5-63 Hz, this drive demonstrates remarkable adaptability to various electrical conditions. The inclusion of an EMC filter and IP21 protection rating ensures reliable performance in demanding environmental conditions where dust and moisture might be present.

Featuring advanced motor control capabilities, the ATV71HC25N4 Schneider IN STOCK supports both asynchronous and synchronous motors with multiple control profiles including Sensorless Flux Vector Control (SFVC) and Flux Vector Control (FVC). The drive offers exceptional speed regulation with accuracy up to ±0.01% in closed-loop mode using encoder feedback, achieving speed ranges from 1:100 in open-loop to 1:1000 in closed-loop configurations for asynchronous motors. These precision capabilities make it ideal for applications requiring exact speed maintenance.

The Variable Speed Drive ATV71HC25N4 torque performance is equally impressive, delivering transient overtorque capabilities of 170% for 60 seconds and 220% for 2 seconds, with a braking torque of up to 150% when used with a braking resistor. The integrated ENA (Energy Adaptation) system efficiently handles unbalanced loads, while the adjustable PI regulator and configurable voltage/frequency ratios provide flexibility for various motor types and application requirements.

With its adjustable switching frequency range of 2.5-8 kHz and Modbus communication capability, the Drive ATV71HC25N4 Schneider represents a comprehensive solution for modern HVAC systems. The drive's sophisticated control algorithms not only ensure precise motor management but also contribute significantly to energy optimization, making the SCHNEIDER ATV71HC25N4 an intelligent choice for building automation applications where efficiency and reliability are paramount.
