Schneider Electric ATV31H075N4 Variable Frequency Drive

Schneider Electric's Telemecanique Altivar 31 ATV31H075N4 is a compact 0.75 kW (1 HP) three-phase variable speed drive designed to precisely control asynchronous motors in industrial environments. It accepts 380–500 V AC three-phase input and delivers the same voltage range on the output, with up to 2.3 A output current (3.6 A at 380 V / 2.7 A at 500 V input) and an adjustable output frequency of 0.5–500 Hz for smooth starts and accurate speed control. The drive uses sensorless flux vector control with PWM, offers a 2–16 kHz switching frequency (adjustable), and includes an integrated EMC filter for simplified panel installations. IP20 protection, panel-mount with heat sink, and an application environment built for industrial motor speed control systems. Common applications include conveyors, centrifugal pumps, ventilation equipment, mixers, packaging machines, and broader manufacturing lines where precise motor speed and energy efficiency matter. Common replacements listed: Schneider Electric ATV320U07N4C, Schneider Electric ATV340U07N4, and Siemens SINAMICS V20 6SL3210-5BE17-5CV0.
