Power Distribution Units
The increasing electrical demands of military vehicles, in both total power managed and the number of consuming devices, have rendered electrical architecture a critical design element. In response, Piedrafita DEFPOWER has developed an extensive range of military PDU (Power Distribution Units) which mark a significant technological advancement, replacing outdated relay and fuse boxes in high-performance military vehicles.
The solid-state technology-based electronic architecture results in compact, lightweight, and fully user-configurable power distribution units. Their mechanical resilience, exceptional thermal efficiency without the need for additional cooling, and low electromagnetic compatibility (EMC) profile make them ideal for meeting the strictest military certifications and ensuring optimal performance in the most demanding environments.
One of the standout features of Piedrafita DEFPOWER’s MILPDU is their ability to efficiently and effectively modernise older generation vehicles. Replacing traditional relay and fuse boxes with solid-state technology not only reduces weight and size but also enhances reliability and survivability in highly demanding environments. The fully programmable switching logic and adaptability to various voltage architectures make these devices an appealing option for a wide range of military applications.
