Transportation Safety and Standards: The Importance of EN50155 and EMC Compliance in Rail Applications
CDS putting Transportation Safety and Standards First
Transportation systems, particularly rail applications, operate in some of the most challenging environments, requiring uncompromising reliability and stringent safety standards. Industrial devices, especially those used in rolling stock, must withstand extreme conditions while maintaining consistent performance for up to 250,000 hours—equivalent to nearly 30 years of continuous operation.
The demands of rail systems are further intensified by limited space, where devices are often installed in close proximity. As a result, these units must function without interfering with one another, adhering to the highest transportation safety and compatibility standards.
Key Challenges in Rail Applications
Environmental Extremes
Rail devices must endure a variety of harsh environmental conditions, from extreme temperatures to continuous vibrations and shocks. These challenges require specialized designs that prioritize resilience and performance.
Moving Applications
The mobility of rolling stock introduces additional complexities, including the need for devices to remain operational under dynamic conditions. Ensuring seamless operation in these environments demands adherence to globally recognized standards, such as EN50155 and IEC 61850.
Core EN50155 Compliance Requirements
With extensive experience in railcar applications, we understand the importance of compliance with the EN50155 standard, which outlines essential requirements for electronic equipment in rolling stock environments. Here are the five key aspects of EN50155 compliance:
- Power Supply Efficiency and Temperature Management
Devices must operate with an efficiency of 85% or higher, supporting a wide range of input voltages and load variations. Temperature monitoring is crucial, especially for rail applications in regions with extreme climate variations.
- Shock and Vibration Resistance
Equipment must withstand significant shocks and vibrations, depending on its mounting position:
- Axle-mounted: Up to 30g shock for 5 hours and 1km/s vibration.
- Body-mounted: Less than 1g vibration and 5g shock.
- Power Supply Input Voltage
EN50155 mandates specific DC input voltage ranges, including 24V, 48V, 72V, 96V, and 110V. Implementing an input capacitor further stabilizes DC input by smoothing out surge currents.
- Efficiency and Reliability
Safety and quality are paramount. EN50155 requires protection against electrical faults, robust wiring and layout, and the use of high-quality connectors. These elements ensure reliability in critical operations.
- Approval Testing
Compliance testing covers a wide range of performance factors, including:
- Visual inspection
- Operation under extreme temperature conditions
- Dry heat testing
- Input voltage range performance
- Surge protection
- Electromagnetic Compatibility (EMC) and Electromagnetic Interference (EMI) testing
This rigorous process ensures that devices meet operational, safety, and compatibility standards before deployment.
