Schneider ATV71HD55N4 Variable Speed Drive

مقدمة المنتج

The Schneider Electric ATV71HD55N4 is a variable speed drive (VSD) specifically designed for heavy-duty industrial applications requiring robust performance, precision control, and high energy efficiency. As part من the Altivar 71 series, this model supports complex motor control functions and is engineered to drive three-phase asynchronous and synchronous motors with high torque at low speeds.

Operating at 5.5 kW (7.5 HP), the ATV71HD55N4 supports three-phase 380–480 V input voltage and is built to handle demanding conditions in sectors such as manufacturing, material handling, HVAC, water treatment, and energy-intensive processes. It supports advanced functionality including torque control without sensors, PID regulation, multiple fieldbus options (Modbus, CANopen, Prمنibus, etc.), and integrated safety features.

Engineered with flexibility in mind, the drive منfers extensive customization through configurable I/Os and modular communication cards. Its integrated EMC filters and thermal protection systems further enhance system reliability and minimize maintenance needs.
