Excellent PLC
Product Introduction
The Schneider Electric ATV61HU55N4 Variable Speed Drive is a higher-power AC drive within the Altivar 61 series, specifically designed for ventilation and pumping applications that demand reliable torque delivery and stable speed regulation. Supporting three-phase motors at 380…480 V, it is well suited for medium-capacity systems where efficiency and operational stability are critical.
This drive integrates advanced motor control functions with a Level 3 EMC filter and an effective heat-sink construction. These features allow continuous-duty operation while reducing electrical interference and maintaining thermal stability under varying load conditions. Smooth motor control helps minimize mechanical stress, contributing to longer equipment service life.
Designed for industrial and infrastructure environments, the unit is commonly used in HVAC systems, water handling installations, and process industries where consistent flow and pressure control are essential.
