ATV31HU55N4A SCHNEIDER ELECTRIC

The ATV31HU55N4A is a variable speed drive (VSD) from Schneider Electric's Altivar 31 series, designed for controlling the speed of three-phase asynchronous motors. This drive is rated for a motor power of 5.5 kW (7.5 horsepower) and is suitable for operation with a 500V three-phase power supply. It incorporates an integrated EMC filter to minimize electromagnetic interference, ensuring compliance with relevant standards and reducing disturbances to nearby equipment. The drive is enclosed in an IP20-rated housing, providing protection against solid objects greater than 12.5 mm, but it is not protected against water ingress, so it is intended for installation in protected environments. The ATV31 series is known for its compact design, ease of installation, and user-friendly interface, making it suitable for a wide range of industrial applications. It offers various control modes, including voltage/frequency ratio (V/f), sensorless vector control, and quadratic V/f, allowing for flexible adaptation to different motor and load characteristics. The drive also features built-in protection functions, such as overcurrent, overvoltage, undervoltage, and thermal overload protection, ensuring reliable and safe operation. Its robust design and comprehensive features make it a reliable solution for optimizing motor performance and reducing energy consumption in various industrial processes. This drive is commonly used in applications such as pumps, fans, conveyors, and other machinery requiring variable speed control.
