Schneider Electric ATV71HU55N4Z Variable Speed Drive

The Schneider Electric ATV71HU55N4Z Variable Speed Drive (Altivar 71 series) delivers precise sensorless vector control for 5.5 kW (7.5 HP) three‑phase motors, enabling tight speed and torque regulation in industrial processes. It operates on 380–480 V AC, 3‑phase supply and provides an output frequency range of 0.1 to 599 Hz, with a rated current around 11–14.3 A depending on voltage and overload capability up to 220% torque for short durations. Communications include Modbus and CANopen; built‑in features include an EMC filter, DC choke, and heatsink; mounting options are wall or panel, with IP20/IP21 protection and an operating temperature of −10°C to +50°C. Designed for constant torque industrial applications and commonly deployed in conveyors, packaging machines, textile machinery, and material handling systems, as well as manufacturing plants, process automation, cranes, and HVAC applications to improve motor control and process efficiency.
