Description
1. Product Description
The ABB 5SHY35L4512 is a robust thyristor module with a rated voltage of 4500 V and current of 3500 A (RMS), optimized for heavy-duty industrial use. Its planar technology and press-pack design ensure low thermal resistance and long-term stability, making it suitable for harsh conditions (-40°C to +125°C). Key features include surge current capability (50 kA), fast switching times, and compatibility with ABB’s modular cooling systems. The module integrates advanced overvoltage protection and diagnostic capabilities, enabling seamless integration into AC/DC conversion systems.

6. Selection Recommendations
- Power Requirements: Ideal for systems requiring 3000–4000 A RMS and 4000+ V.
- Cooling Systems: Pair with ABB’s liquid-cooled heat sinks for optimal performance in high-duty cycles.
- Environment: Suitable for outdoor/harsh environments with IP65 enclosures.
- Compatibility: Ensure alignment with ABB’s thyristor driver boards (e.g., 5SDD/5SSH series) for full functionality.
7. Precautions
-
Installation: Torque mounting bolts to 25–30 N·m (avoid over-tightening).
-
Cooling: Maintain heat sink temperature <85°C (liquid cooling recommended for continuous operation).
-
Voltage Handling: Use snubber circuits to mitigate voltage spikes (recommended: 10 Ω/100 µF per module).
-
Maintenance: Inspect contact pressure annually; replace modules every 15 years (expected lifecycle).
