Simplify Railway Power Architecture with One Ultra-Wide Input DC/DC Converter

As railway systems become increasingly connected and intelligent, engineers face growing pressure to deliver reliable power architectures that can support multiple vehicle platforms without increasing design complexity.

AUTRONIC HFC150-W/G 150W DC/DC converter has been developed specifically for railway and demanding industrial applications. With an ultra-wide 14.4–154VDC input range, a single converter can support the most common onboard railway voltage systems, helping to reduce design variants, simplify qualification and standardise future projects.

Instead of designing around individual nominal voltages, engineers can develop a common power architecture capable of supporting 24V, 36V, 48V, 72V and 110V railway systems.

This approach delivers practical engineering benefits:

• Reduce converter variants across multiple platforms
• Simplify design and qualification
• Lower inventory and spare parts
• Improve long-term serviceability
• Standardise future developments

Whether powering embedded computing, passenger information systems or vehicle control electronics, the HFC150-W/G is engineered for dependable performance in harsh railway environments.

Key Features

• 150W continuous output
• 14.4–154VDC ultra-wide input
• Up to 93% efficiency

• 10ms hold-up capability

• –40°C to +85°C operating temperature
• 24V, 48V, ±15V and ±24V output options
• Remote Enable, Power Good and Thermal Warning signals
• Comprehensive protection including reverse polarity and short-circuit protection

The HFC150-W/G has been developed to support demanding transportation applications and complies with key railway standards, including:

• EN 50155
• EN 50121-3-2
• EN 45545-2

Combined with galvanic isolation and integrated protection functions, it provides a robust foundation for long-life railway electronics. Modern rolling stock increasingly combines embedded computing, communications, diagnostics and intelligent monitoring.

The HFC150-W/G provides the stable, efficient power these systems require while allowing engineers to develop scalable architectures that can be reused across multiple vehicle platforms.

Typical applications include:

• Passenger Information Systems (PIS)
• Customer Information Systems (CIS)
• Embedded computers
• Communications equipment
• Vehicle control systems
• Diagnostics and condition monitoring
