Schneider Electric ATV31HU30N4 Variable Frequency Drive

Schneider Electric ATV31HU30N4 is a 3 kW (4 HP) variable frequency drive from the Altivar 31 family, designed to control three-phase AC motors at 380–500 V. It uses sensorless flux vector control with PWM, offers an output frequency range of 0.5–500 Hz, and provides an adjustable switching frequency from 2 to 16 kHz to ensure smooth starts and precise speed and torque control. The drive accepts 380–500 V three-phase input and delivers 380–500 V three-phase output, with a 7.1 A output current and an input current of 10.9 A at 380 V or 8.3 A at 500 V, operating on a 50/60 Hz supply. It includes an integrated EMC filter, IP20 protection, and panel-mount with a heat sink, making it well-suited for industrial motor speed control in conveyors, centrifugal pumps, ventilation equipment, mixers, packaging machines, and manufacturing production lines.
