On Track with EN 50155

EN 50155 compliance isn't just a checkbox, it's the starting point for reliable railway power design. Bel is keeping you on track with a practical guide to understanding the standard and selecting the right ruggedized power converters for your rolling stock application.

White Paper Overview

Railway applications demand power solutions that can withstand the harshest environmental conditions, from extreme temperatures and mechanical shock to Electromagnetic Interference (EMI) and voltage fluctuations. For power supply designers working in rolling stock applications, understanding and meeting EN 50155 is not optional; it is the foundation of a safe, reliable, and certifiable design.

This guide brings together two essential resources for railway power engineers. First, a deep dive into EN 50155, the definitive standard governing electronic equipment used in rolling stock, breaking down its key requirements and what they mean for your power supply design decisions. Then, practical guidance on selecting ruggedized power converters for rolling stock applications, including the performance characteristics, form factors, and compliance considerations that separate a capable solution from the right one.

At Bel, we are committed to keeping you on track, with the products, expertise, and resources engineers need to design confidently for the rail environment.
