Schneider Electric SE ATV71HU55N4 Variable Frequency Drive

The Schneider Electric Telemecanique ATV71HU55N4 AC Drive is a 5.5 kW (7.5 HP) three‑phase variable frequency drive built for precise speed and torque control of both asynchronous and synchronous motors in industrial systems. Part of the Altivar 71 family, it accepts 380–480 V AC input and provides 380–480 V AC output, with nominal output currents of 11 A at 460 V (14.3 A at 380 V) and line currents of 17 A at 480 V (20.3 A at 380 V), delivering up to 13.4 kVA. It supports 50/60 Hz supply and an output frequency range of 0.1–599 Hz, with control methods including Sensorless Flux Vector, Flux Vector with encoder, V/F control, and Energy Adaptation (ENA). An integrated EMC filter, IP20 protection, and panel‑mount with heat sink suit industrial motor speed control applications. Communications options include Modbus and CANopen. Common applications include HVAC systems, water and wastewater facilities, material handling, manufacturing plants, and mining operations where reliable motor control and energy efficiency are essential. Common replacements listed are Schneider Electric ATV340U55N4 and ATV930U55N4, as well as Siemens SINAMICS G120X 5.5 kW.
