Industrial Applications and Operational Use Cases

The DSSB140 is a fundamental component for facilities utilizing ABB Advant OCS platforms where data persistence is a regulatory or operational requirement.

• MasterPiece 200 Memory Protection Providing the localized voltage source required to prevent the loss of RAM-resident user programs and system configurations during facility shutdowns.

• Continuous Process Industries Serving as a fail-safe power link for controllers in refineries and chemical plants where a "cold start" due to memory loss would result in significant production delays.

• Substation Automation Ensuring the real-time clock (RTC) remains synchronized for accurate event logging and time-stamping during power grid disturbances.

• Redundant Power Configurations Operating alongside secondary power supplies to provide a third-tier energy source for mission-critical logic solvers.

• System Maintenance and Overhaul Acting as a drop-in replacement for aging Advant Master hardware, allowing for easy battery cell rotation without disrupting the permanent wiring of the rack.
