Schneider ATV71HU55N4 Variable Speed Drive

مقدمة المنتج

The Schneider Electric ATV71HU55N4 is a high-performance Variable Speed Drive (VSD) designed to control three-phase asynchronous and synchronous motors across a wide range من industrial applications. As part من the Altivar 71 series, this 5.5 kW drive (equivalent to 7.5 HP) supports advanced motor control techniques such as sensorless vector control, flux vector control, and voltage/frequency (V/F) ratio control.

Tailored for demanding processes that require dynamic response, precision, and robust reliability, the ATV71HU55N4 is widely used in sectors like material handling, packaging, HVAC, pumping systems, and more. It is engineered with built-in Modbus and CANopen communication, Safe Torque Off (STO), and supports additional protocols through modular expansion.

This model not only enhances process efficiency and energy savings, but also ensures machine safety, low downtime, and adaptability across evolving system architectures.
