We are delighted to announce a new project with one of the leaders in the airport equipment sector.

We took on the challenge of developing a high-voltage Power Distribution Unit (PDU) for an aircraft tractor model. With three 400V batteries in parallel, a maximum current of 900A and a power output of 200kW, routing all this energy through the PDU was a technical challenge that we successfully met.

The PDU distributes the power from the batteries to the vehicle’s various essential functions: powertrain, heating, air conditioning, DC/DC converters, etc.).


Inside the PDU, the power is distributed via copper busbars. For auxiliary power requirements, a PCB was designed by our team and then integrated, housing smaller fuses for effective protection.

The switch to high voltage posed challenges in terms of respecting insulation distances between components, but by working closely with our customer, we were able to develop this project through to series production in just a few months.
