UPS solution developed for railway infrastructure requirements

The DEWEN TITRON RailGuard Series is a heavy-duty online UPS platform engineered for railway, transportation, and mission-critical infrastructure where electrical, mechanical, and environmental stresses exceed standard industrial conditions. The platform is available now from Luso Electronics.

Based on the proven TITRON industrial UPS architecture, the series includes railway-specific design considerations, including improved mechanical robustness, improved shock and vibration tolerance, and EMC behaviour appropriate for rolling stock and trackside environments.

The system delivers continuous, high-quality power for signalling, control, communications, SCADA, and auxiliary railway loads, ensuring maximum availability in demanding operating conditions.

Key Features

• Double-conversion online topology for zero transfer-time power protection
• High overload capability to support railway transient loads
• Enhanced mechanical robustness for shock and vibration-prone environments
• Wide input voltage and frequency tolerance suitable for unstable grids
• High efficiency operation, including partial load efficiency optimisation
• Low output voltage ripple, extending battery service life
• Redundant and monitored cooling system for high availability
• Parallel operation capability for capacity expansion and redundancy
• Flexible battery configurations (VRLA standard, Lithium-ion optional)

Industrial-grade communication interfaces for system monitoring and control
