Scada Control system – CQ2660-9R

CASE STUDY
“We need a 20mm profile DC DC converter for our SCADA system.”

Request

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.

  • Q series

    Input: Wide input (2:1)
    Outputs: 5 to 48V
    Power: 120 Watt
    Tamb: -40 to +71°C
    Dims: 168 x 111 x 20mm (3U x 4TE)
    UL / CE EN60950 Approved
    5 year warranty

Refine

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.

  • HP series

    Input: 12.5 to 154Vdc
    Outputs: 5 to 96V
    Power: 150 Watt

    UL / CE EN60950 Approved
    5 year warranty

Result

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.
