The Schneider Electric ATV71HD15N4 is a powerful frequency inverter of the Altivar 71 series with a rated power of 15 kW (20 HP). It operates in the 3-phase range of 380–480 V and features an integrated EMC filter, a graphical display, as well as a heat sink for continuous industrial use. The inverter supports a wide output frequency range (0.1–599 Hz) and is ideal for demanding machine controls, as it offers both sensorless and sensor-based vector control (SFVC, FVC) as well as the ENA system for unbalanced loads. With integrated communication protocols such as Modbus and CANopen, it is flexibly networkable and optimal for modern automation solutions. This VFD combines precision, efficiency, and industrial robustness for diverse application fields.
