Product Introduction
The Schneider Electric ATV320U55N4B Variable Speed Drive is part of the Altivar Machine ATV320 series, designed to supply and control both three-phase synchronous and asynchronous motors. With a rated power of 5.5 kW (7.5 hp) and a wide supply voltage range of 380–500 VAC, it is well suited for industrial machinery requiring precise speed, torque, and dynamic performance.
This drive is engineered for demanding industrial environments. Its coated printed circuit boards, compliant with IEC 60721-3-3 class 3C3, ensure reliable operation even in harsh conditions such as elevated temperatures, dust, and humidity. The drive can operate at ambient temperatures up to 60°C without additional cooling, maintaining stable performance and reducing system complexity.
The ATV320 integrates advanced motor control technologies, including sensorless vector flux control, enabling accurate torque and speed regulation even at very low speeds. It also supports an extended output frequency range, making it suitable for high-speed motor applications. Energy-efficient open-loop control for synchronous motors is available, helping to reduce power consumption in continuous-duty systems.
Designed specifically for OEM machine builders, the ATV320 supports a wide range of simple to advanced applications in packaging, material handling, textiles, material processing, mechanical actuators, and lifting systems. Integrated safety functions, configurable via SoMove software, help machines meet modern safety requirements with or without external Preventa safety modules.
