ABB SB171 3BSE004802R1 Backup Power Supply – Advant Controller 160 Series
When a backup power supply fails in a live industrial control system, the consequences are immediate and severe: unplanned shutdowns, loss of process data, potential equipment damage, and costly production downtime that can run into thousands of dollars per hour. In distributed control environments running ABB’s Advant platform, the SB171 (3BSE004802R1) is the critical last line of defense — the module that keeps your controller alive and your process data intact when primary power is interrupted.
The ABB SB171 3BSE004802R1 is a dedicated backup power supply module engineered specifically for the Advant Controller 160 (AC160) series — one of ABB’s most widely deployed mid-range DCS platforms in process industries worldwide. As part of the 3BSE-prefixed hardware family, this module meets ABB’s stringent industrial-grade reliability standards and is designed for long-lifecycle deployment in demanding environments including oil & gas, pulp & paper, power generation, and chemical processing plants.
