3BSE004802R1 SB171 ABB Backup Power Supply

The ABB 3BSE004802R1 (also known as SB171) is specifically identified as a Backup Power Supply Module within ABB's Advant Master Process Control System.Its primary purpose is to ensure the continuous and reliable operation of critical industrial processes by providing an uninterruptible power source in the event of a main power failure.

Output Power Supply: Typically provides a regulated 24V DC output at 5A to power the Advant Master controllers, I/O modules, and other critical components.

Input Power Requirement: Requires a standard 120/230 VAC input (depending on configuration) to operate its charging and primary power supply functions.

Integrated Design for Advant Master: Specifically engineered to integrate physically and electrically with the backplane and power distribution architecture of the ABB Advant Master DCS. 

Compact Form Factor: Designed as a module to fit neatly within the Advant Master system's chassis or rack. 

Power Generation: Applied in thermal, hydro, and nuclear power plants to maintain control over turbines, generators, boilers, and auxiliary systems, preventing costly trips and ensuring grid stability.

Metals Industry: Used in steel mills, aluminum smelters, and other metal processing facilities to maintain control over furnaces, rolling mills, and casting operations.

Utilities: Beyond power generation, it supports control systems in water distribution, gas networks, and other essential services.

Transportation: While less common, in large-scale transportation control centers that use Advant Master, it would ensure continuous operation.

Water and Wastewater Treatment: Provides reliable power to control pumps, valves, filtration systems, and chemical dosing, ensuring continuous service and environmental compliance.
