Schneider Electric ATV340U75N4 Variable Frequency Drive

Schneider Electric ATV340U75N4 is a 7.5 kW Altivar Machine ATV340 variable-frequency drive designed for 400 V three-phase motor control in industrial automation, delivering precise speed and torque regulation for powered equipment. The U75N4 variant sits in the ATV340 family’s 7.5 kW heavy-duty range, with the platform supporting motor powers from 0.75 kW up to 30 kW in heavy-duty configurations (and 1.1 kW to 30 kW in normal-duty, depending on the model). It is intended for use on three-phase, 380–480 V systems, commonly configured around 400 V. An integrated Category C3 EMC filter with 20 m shielded motor cable is part of the ATV340 design, simplifying installation in noisy industrial environments. An Ethernet-enabled variant (ATV340U75N4E) is also available, while the base U75N4 denotes the non-Ethernet version. This drive is suited for machine-level control tasks in automation, such as conveyors, pumps, fans, and other motor-driven applications that require reliable speed control and robust performance.
