The Schneider Electric Altivar 61 Variable Frequency Drive (VFD) — ATV61HU40N4Z — is a compact industrial variable‑speed drive designed for pumping and ventilation machine applications. It supports three‑phase motors rated at 4 kW (5 HP) on a 380…480 V AC, 3‑phase supply. The drive features an integrated Level 3 EMC filter and multiple motor control profiles (including sensorless vector and U/f control), offering energy‑efficient, precise speed and torque regulation. It includes standard communication protocols (Modbus, CANopen) and is suitable for a wide range of industrial HVAC and process control systems.
