Network Rail is upgrading to a new SCADA (Supervisory Control & Data Acquisition) system, to control traction power and distribution across the national rail network in the UK. As part of this our client needed to power his 24Vdc system from the trackside 48Vdc battery backed supply using an EN50121 compliant system.
We had to find a module that fitted with a 20mm height profile, but we also took them through their EMC requirements (needed EN55022 class B), thermal considerations (kitchens get warm) and long term reliability of the product.
The engineering team at Relec worked closely with the customer to identify the best possible solution. We were able to bring to bear our extensive experience in the area of power conversion for railway applications. Our recommendation was the well-established Q series from Bel Power Solutions. The model offered has the benefit of Network Rail PADS (Parts And Drawing System) approval. We supplied extensive documentation to support the design-in and approval of the customer’s equipment, and extended application support both at the factory and at the installation site.
