Unique tailoring opportunities

The Power Management and Distribution system architecture is modular, offering a unique opportunity for tailoring the design to mission-specific requirements, while at the same time still benefiting from a standardized and qualified solution. The enhanced flexibility and adaptability facilitate convenient assembly, integration, and testing of the satellite.


Our Power Management and Distribution (PMAD) system is a flight-proven modular concept qualified for deep space and Earth orbit missions. The unique system maximizes power efficiency and utilization in satellite missions.

The power system functions are designed with the latest state-of-the-art power technology to enhance reliability and power-to-weight performance, while utilizing high frequency switched-mode power conversion technology to minimize unit mass.

The system scales to a power capacity of up to 15 kW and offers all classical applied power system functions, including failure tolerant Maximum Power Point Tracking capability.
