ATV31HD15N4A

The Schneider Electric ATV31HD15N4A is a compact variable-speed drive (VFD) from the Altivar 31 series designed to control three-phase asynchronous (induction) motors. It provides smooth motor speed and torque regulation for simple machines in industrial and commercial applications. The drive includes an integrated EMC filter and sensorless control to optimize motor performance while reducing electrical interference and mechanical stress, making it suitable for applications such as pumps, fans, conveyors, compressors, and other motor-driven equipment.
