Description
1. Product Description
The ABB DSSB140 48980001-P is a high-reliability battery backup unit designed for industrial control systems, providing uninterrupted power to critical processes during mains outages. Engineered for ABB’s DSSB series (e.g., Advant OCS/S100 I/O systems), the DSSB140 48980001-P ensures seamless transition to backup power, protecting data integrity and preventing system downtime. Its compact design (72x36x216 mm) and lightweight construction (0.42 kg) enable easy integration into control panels, while compliance with industrial standards (IEC 62619, UL 1642) guarantees safety and durability. The unit supports hot-swap battery replacement and is compatible with ABB’s modular automation platforms, making it ideal for energy, manufacturing, and infrastructure sectors.

3. Advantages and Features
- Rugged Reliability: MTBF > 100,000 hours (ABB testing), with surge protection (600V transient) and flame-retardant housing (UL 94 V-0).
- Compact Design: 30% smaller than legacy backup units, saving panel space in industrial cabinets.
- Hot-Swap Capability: Replace batteries without system shutdown, reducing maintenance downtime by 70%.
- Flexible Configuration: Supports multiple battery chemistries (Li-ion, NiMH) for custom runtime (15–60 minutes typical).
- Case Study: A solar farm in Spain used 50 DSSB140 48980001-P units to power tracking systems during grid outages. The hot-swap feature and 12V DC compatibility ensured 99.9% uptime, increasing energy yield by 8%.
4. Application Areas and Use Cases
Industries: Renewable energy (solar/wind), manufacturing (robotics), water treatment, and smart infrastructure.
典型场景:
典型场景:
- Solar Farms: Powers tracker controllers and data loggers during grid outages.
- Wind Turbines: Maintains pitch control and safety systems during transient faults.
- Factory Automation: Protects PLCs and HMIs during power fluctuations, preserving process data.
5. Competitor Comparison
Compared to similar backup power units:
- Superior Compatibility: Native integration with ABB’s DSSB ecosystem (vs. generic adapters required by competitors).
- Temperature Range: Operates 10°C colder (-20°C vs. -10°C) for outdoor/extreme environments.
- Safety Standards: UL 1642 certification for lithium-ion batteries (vs. basic safety in mid-range alternatives).

6. Selection Recommendations
- Compatibility: Verify integration with ABB DSSB modules (e.g., DSSB110, DSSB120).
- Battery Selection: Match capacity (Ah) to runtime needs (e.g., 2 Ah for 15 minutes, 10 Ah for 60 minutes).
- Environment: Use IP54 enclosures (optional) for dusty/humid sites; standard IP20 for indoor use.
- Budget: Balance battery type (Li-ion vs. NiMH) and runtime—Li-ion offers 2x lifespan but higher cost.
7. Precautions
- Installation: Follow ABB’s wiring guidelines (AWG 18–22 for signal cables; AWG 14–16 for power).
- Battery Handling: Use anti-static gloves; replace batteries every 3–5 years (Li-ion) or 2–3 years (NiMH).
- Safety: Disconnect mains power before battery replacement; never short-circuit terminals.
- Maintenance: Test backup functionality quarterly; monitor battery health via ABB’s System 800xA.
