Smallsat Power Conditioning & Distribution Units

For larger small satellites, our STARBUCK-MICRO Power Control and Distribution Units (PCDU) will provide reliable and efficient power handling for your mission. With the ability to utilise either a Direct Energy Transfer or Maximum Power Point Tracker architectures, these larger EPS units are able to meet most small satellite mission demands.  The Starbuck-Micro design builds on heritage from previous missions with customers such as ESA, NASA, JAXA and other commercial organisations. A number of design features are implemented to achieve optimized reliability characteristics.

The Starbuck-Micro PCDU (Power Conditioning and Distribution Unit) was initially developed under a Swedish national mission and tailored to the requirements of the LEO microsatellite bus InnoSat. This is a state-of-the-art spacecraft architecture designed for innovative low cost research missions. High-performance power solution for small satellite platforms.

Its modular design approach delivers scalability and easy tailoring of interfaces, equipment can be accommodated through the addition of modular design elements to mission requirements.

The flexible and modular PCDU is designed for mission life of up to five years in LEO and implements both power conditioning and distribution of the regulated 28 V battery bus, as well an auxiliary isolated 5 V bus.
