DESCRIPTION DU PRODUIT
SCHNEIDER ELECTRIC ATV71HC25N4 - Variable Speed Drive
This Altivar 71 series variable speed drive is engineered for high-performance control of three-phase asynchronous and synchronous motors in complex industrial machinery. It provides advanced sensorless flux vector control and sensor vector control capabilities, optimizing motor performance for applications requiring high torque at low speeds, precise speed regulation, and dynamic response, including hoisting, material handling, and process control systems.
