ABB SA811F Power Supply

Description

The ABB SA811F Power Supply is a single-phase AC power module designed for a wide range of industrial and commercial applications, including mechanical control systems, automation equipment, test and measurement instruments, and communication systems. As part of ABB’s SMPS 1000 series, it delivers stable, reliable power support for connected devices. Key technical specifications include a broad input range of 85-265 Vac with a maximum input current of 2.5A, and a regulated output of 12 Vdc at a maximum current of 10A, providing a total power output of 120W with a high conversion efficiency of up to 89%. It operates in temperatures ranging from -20 degrees Celsius to +70 degrees Celsius, with an IP20 enclosure protection rating. The module features screw-type input/output terminals, support for on/off and voltage adjustment control signals, and comprehensive protection functions including overvoltage, overcurrent, and short-circuit protection. It also maintains output for at least 20ms during power failures to prevent unexpected device shutdowns. With a compact footprint of 105 x 60 x 30mm and a weight of 250g, it saves installation space, and carries UL, CE, and CB certifications for compliance with global standards.
