110V Railway supply simulator / Ultimod Series

"We needed a PSU to replicate a train 110V and we need it tomorrow!"


We were contacted by one of our regular customers looking to simulate the 110Vdc train-borne supply voltage from an ac supply. The solution needed to be quickly available and relatively easy to implement for an urgent requirement. The solution also needed to be robust enough to be installed in a mobile transit case without posing a reliability risk.

  • Ultimod Series

    Input: 85-264Vac
    Outputs 1 to 12 - 1.0 to 58V
    Power: 600 / 1200 Watt
    Tamb: -40 to +70°C
    Dims: 280 x 90/127 x 40.4mm
    UL / CE EN60950 EN60601 Approved


Given the depth of our product portfolio we were able to offer three potential solutions with different technical / commercial attributes. A key consideration for the customer was the form factor (low profile) and to have the ability to uprate the product if necessary.

  • CoolX600 Series

    Input: 85-264Vac
    Outputs: 1 to 4, 2.5 to 58V dc
    Power: 600 Watt
    Tamb: -40°C to +85°C
    Dims: 216 x 114 x 39 mm

After a series of short discussions we settled on a solution utilising the Excelsys Ultimod configurable power supply family. The Ultimod series offers field proven reliability and a 5 year warranty for peace of mind. We were able to offer a solution capable of providing 400Watts @ 110V DC with the possibility to increase the power output by adding an further DC power module.

Due to the products flexible / configurable design, it was easy for us to ship a tailored solution to our customer within 24 hours.
