Overview

The ABB PFSA140 Roll Supply Unit is a specialized module used to power and control roll-based mechanisms in automated systems. It is commonly integrated into ABB’s distributed control platforms, including the AC 800M and 800xA systems. Moreover, the unit provides constant current output at a fixed frequency, ensuring smooth and accurate roll movement. Its compact design and robust construction make it suitable for installation in control cabinets and industrial enclosures. In addition, the PFSA140 supports high-speed signal processing and precise load regulation, essential for synchronized motion applications.

Technical Data / Specifications

Typical Applications 

The PFSA140 is widely used in automated manufacturing lines where roll feed control is critical. It powers and regulates motors or actuators that drive rollers in packaging, printing, or textile machinery. For instance, in paper processing plants, the module ensures consistent tension and speed across multiple roll stations. In addition, it integrates with ABB’s AC 800M controllers to support synchronized motion and real-time feedback loops. Its high-frequency output and stable current delivery make it ideal for precision-driven applications requiring minimal fluctuation.
