Key Features and Advantages
The ABB DSSB140 is distinguished by its comprehensive feature set, engineered to meet the most demanding industrial power reliability requirements.
High Energy Density and Compact Design
The DSSB140 achieves exceptional 3.36 kWh energy storage within a compact 300 mm × 160 mm × 240 mm footprint, delivering 300 % higher power density compared to traditional lead-acid battery solutions . This space-efficient design significantly reduces control cabinet footprint requirements while providing substantial backup capacity. The 20 kg aluminum enclosure integrates all components into a single, easily installable unit that occupies 60 % less volume than conventional UPS systems with equivalent capacity .
Millisecond Switching Technology
The module incorporates advanced MOSFET-based bidirectional DC-DC conversion technology that achieves seamless power switching in less than 1 millisecond during main power failures . This ultra-fast transition ensures that connected PLCs, HMIs, and control systems continue operation without interruption, preventing process disturbances, data loss, or unsafe conditions. Critical control loops maintain functionality throughout power disturbances, eliminating the need for system restarts or manual intervention.
Intelligent Battery Management System
The integrated BMS provides comprehensive battery monitoring and optimization capabilities :
-
Real-time Cell Monitoring: Continuous supervision of individual cell voltage, temperature, and internal resistance
-
Lifetime Prediction: Advanced algorithms predict remaining battery life with 30-day advance warning for replacement needs
-
State of Charge Accuracy: Online SOC and SOH calibration maintains error less than 2 % for precise capacity management
-
Comprehensive Protection: Over-voltage, under-voltage, over-current, and short-circuit protection for all operating conditions
Wide Temperature Range Operation
Engineered for extreme environments, the DSSB140 operates reliably from -25 °C to +70 °C without performance degradation . This wide temperature tolerance enables deployment in harsh industrial settings including Arctic LNG facilities, desert solar installations, and unheated outdoor enclosures. The IP65-rated aluminum housing provides protection against condensation, dust, and water spray, allowing direct outdoor installation without additional enclosures .
Hot-Swap Maintenance Capability
The DSSB140 features innovative drawer-style battery slide rails that enable complete battery replacement in under 5 minutes without tools . During replacement, Modbus registers automatically synchronize parameters for zero-configuration commissioning. This hot-swap capability eliminates system downtime for maintenance and allows battery replacement to be scheduled during normal operations without affecting production.
Comprehensive Communication and Integration
Multiple communication interfaces ensure seamless integration with automation systems :
-
Standard RS-485 / Modbus RTU: Native integration with ABB and third-party control systems
-
Optional PROFIBUS DP: Direct connectivity to PROFIBUS networks
-
Optional Modbus TCP: Ethernet-based communication for remote monitoring
-
Optional CANopen: Interface for inverter and drive system integration
-
Automatic Parameter Mapping: Modbus registers 40001-40010 automatically map to PLC variables
