Schneider ATV71HU55Y Variable Speed Drive

Product Introduction

The Schneider Electric ATV71HU55Y is a robust, high-performance Variable Speed Drive (VSD) developed to handle demanding motor control tasks in complex industrial processes. It belongs to the Altivar 71 series, which is known for its precision motor control, advanced safety, and modularity.

This specific model, rated at 5.5 kW (7.5 HP), is engineered for three-phase 200–240V power systems, ideal for regions or applications that use lower voltage standards. With features like sensorless flux vector control, voltage/frequency ratio control, and flux vector control with feedback, it provides precise regulation of motor speed and torque in both synchronous and asynchronous motors.

Integrated Modbus and CANopen communications, Safe Torque Off (STO), multiple I/O options, and a compact design make the ATV71HU55Y a versatile solution for OEMs, system integrators, and end users.
