Maximizing Panel Space with the ATV320U04N4B Schneider Electric variable speed drive

The ATV320U04N4B Schneider Electric variable speed drive is a state-of-the-art motor controller from the Altivar 320 series, engineered specifically for modern, high-density machine designs. This 0.37 kW drive combines a remarkably narrow “Book” form factor with the advanced safety and communication features required for complex machinery. It is the perfect solution for applications with multiple drives in a single cabinet, such as conveying systems, packaging lines, and textile machines, where panel space is a critical resource.

The “Book” Form Factor Advantage of the ATV320U04N4B Schneider Electric variable speed drive

The standout feature of the ATV320U04N4B Schneider Electric variable speed drive is its innovative “Book” style design. This slim profile allows for direct side-by-side mounting with minimal to no ventilation clearance, enabling a significant reduction in control panel width and overall cost. This space-saving advantage is complemented by high-end integrated features. The standard Safe Torque Off (STO) function simplifies the creation of safety circuits, reduces the need for external contactors, and helps achieve machine safety compliance (SIL 3). This combination of compact size and integrated functionality is a major benefit for today’s machine builders.

High-Performance Control and Robust Reliability

Despite its small size, the ATV320U04N4B Schneider Electric variable speed drive delivers the powerful performance and robust quality Schneider Electric is known for. It provides high-performance flux vector control for both asynchronous (induction) and synchronous motors, ensuring precise speed and torque regulation for even the most delicate tasks. Built for a long service life in demanding industrial environments, its printed circuit boards are conformally coated to protect against dust and moisture, guaranteeing operational reliability.

Key Features and Design Benefits of the ATV320U04N4B Schneider Electric variable speed drive
