LWN2660-6 ABB
ABB LWN2660-6 stands out for its rugged durability and energy efficiency. The module’s reinforced housing and wide temperature range (-25°C to +60°C) make it suitable for extreme industrial environments, such as steel mills or outdoor installations. Its high-efficiency design (up to 92%) reduces energy waste and heat generation, lowering operational costs. The built-in active PFC (Power Factor Correction) ensures compliance with global energy standards, while the compact size saves up to 30% space in control cabinets compared to legacy models. In a food processing plant, LWN2660-6 demonstrated 99.9% uptime over three years, outperforming generic power supplies in reliability.
Industry Applications:
- Manufacturing: Powering PLCs, HMIs, and sensors in automated assembly lines.
- Energy and Utilities: Providing stable power for renewable energy inverters and substation control systems.
- Transportation: Railway signaling and tunnel ventilation systems.
- Process Control: Chemical plants and water treatment facilities requiring fail-safe power.
Case Study: A automotive manufacturer integrated ABB LWN2660-6 into its robotic welding cells. The module’s fast transient response (≤50 ms) and noise suppression features ensured stable power for high-precision sensors, reducing weld defects by 20%. Its redundant power input capability also minimized downtime during maintenance, improving overall line efficiency by 15%.
Compared to similar power supplies, ABB LWN2660-6 offers superior EMC/EMS performance and flexible mounting options. While some competitors lack adjustable voltage features, LWN2660-6 allows fine-tuning to match specific device requirements, reducing the need for external regulators. Its dual voltage input (AC/DC) and global certifications simplify deployment in multi-regional projects, a key advantage over single-input models.

- Voltage Compatibility: Ensure the input voltage range matches your site’s power supply (AC/DC) and regional standards.
- Load Requirements: Calculate total current draw of connected devices, leaving a 20% margin for peak loads.
- Environmental Needs: Choose this module for high-humidity or dusty environments, as its IP20 rating protects against solid particles and limited moisture.
- Scalability: For large systems, consider parallel operation with identical modules (using a load-sharing kit) to increase power capacity.
- Installation: Mount vertically for optimal airflow and avoid blocking ventilation slots. Use stranded copper wires (14–22 AWG) for secure connections.
- Wiring Safety: Separate power cables from signal cables to prevent EMI interference. Ground the module properly to comply with safety regulations.
- Maintenance: Regularly inspect for loose connections or corrosion, especially in high-vibration environments. Clean dust from the heatsink annually to maintain thermal performance.
- Redundancy: For critical applications, pair with a redundant power module or UPS to ensure uninterrupted operation during power outages.
