Schneider ATV61HU40N4 Variable Speed Drive

Product Introduction

The Schneider Electric ATV61HU40N4 Variable Speed Drive is a high-capacity AC drive from the Altivar 61 range, engineered for precise and efficient control of motors used in pumping and ventilation machines. It is designed to operate with three-phase power supplies in the 380…480 V range, providing stable speed regulation for demanding industrial and infrastructure applications.

This drive combines advanced motor control algorithms with an integrated EMC filtering solution and an effective heat-sink assembly. These features support continuous operation, reduce electrical interference, and help maintain reliable performance under varying load conditions. The drive also contributes to smoother motor operation, lowering mechanical stress and improving overall system efficiency.

Optimized for energy-intensive applications, the unit is well suited for systems where accurate flow and pressure control are critical, such as HVAC installations, water management systems, and industrial process equipment.
