We asked our specialists to explain why P-Duke DC/DC converters are considered ideal for railway applications. They advised this was due to their compliance with strict railway standards and robust design characteristics tailored to the challenging conditions of railway environments. Here is what else they told us about their suitability:
Railway-Specific Standards Compliance
P-Duke converters meet international railway standards, including:
- EN 50155 – Covers electronic equipment used on rolling stock (e.g., temperature, shock, vibration, humidity, voltage range).
- EN 45545-2 – Fire and smoke protection for railway applications.
- EN 50121-3-2 – Electromagnetic compatibility (EMC) for railway environments.
- Surge Suppression Modules – enable compliance with RIA12
Wide Input Voltage Ranges
- Designed to support standard railway voltages: 24V, 48V, 72V, 96V, and 110V (and accommodate transient tolerance).
- Typical input ranges of 4:1 (e.g., 43–160VDC), and others with 12:1 input range, meaning they can handle significant voltage fluctuations and surges.
. Rugged and Reliable Design
- Wide operating temperature range: –40°C to +105°C, suitable for harsh climates.
- High MTBF (Mean Time Between Failures): Enhances reliability in long-term deployments.
- Conformal coating: Protects against moisture, dust, and other contaminants.
Low EMC Emissions & High Immunity
- Excellent electromagnetic compatibility to avoid interference with sensitive railway signalling systems.
. Compact & Modular Form Factors
- Suitable for space-constrained installations on locomotives, carriages, or control systems.
Built-in Protections
- Over-voltage, over-temperature, short-circuit, and input under-voltage protections ensure safety and longevity.
Customisable & Scalable
- Options for parallel operation, redundancy, and custom configurations to suit different subsystems (e.g., lighting, control electronics, communication).
Typical Uses of dc/dc converters in Rail Applications:
- Train control and monitoring systems
- Passenger information displays
- Surveillance and communication equipment
- Onboard networking and Wi-Fi
- Auxiliary power systems
