Overview

The ABB PFSA140 3BSE006503R1 Roll Supply Unit Module is designed to deliver stable power and precise control for roll-based motion systems — including coil feeders, web handling machines, and roll drives. As part of ABB’s industrial automation platform, it regulates both current and frequency to maintain smooth, accurate mechanical movement across varying loads.

Its compact footprint and rugged build make it well-suited for installation inside control cabinets and automated equipment. With constant current output and 2 kHz operating frequency, the PFSA140 ensures highly responsive motion performance, even in demanding production environments.

Manufactured in Switzerland to stringent international standards, it provides long-term operational reliability and simplified integration for modern and retrofit automation systems.

Technical Data

Typical Applications

The PFSA140 is frequently deployed in automated systems requiring precision roll control and synchronized motion, such as:
