Power Distribution Unit (PDU-DC)

Flexible and scalable solutions to manage electrical loads in aeronautical systems, whether they be state-of-the-art or from previous generations

The PDU-DC solution is designed to ensure the efficient use of the aircraft’s power.

It is composed of a motherboard that controls nine independent power supply boards. The motherboard features a redundant/dual power supply (primary and auxiliary) that are hot-swappable between them (less than 500 μs), providing smooth, continuous power to the daughterboards without interruptions. Additionally, it has full-duplex redundant/dual RS-485 ports, to control the opening/closing of the solid-state power controllers.

It has a modular design, which allows you to configure the number of inputs/outputs and the power supply voltage.
