About
The STARBUCK-MINI is a SmallSat Power Conditioning and Distribution Unit (PCDU) designed for high-performance power control across various missions. Upgraded to deliver 2.5 kW of solar input power (67% increase from previous 1.5 kW versions), it enables higher-power payloads and extended mission flexibility. The modular, scalable architecture allows configuration with up to 15 modules for tailored performance. Features include COTS components combined with radiation-hardened parts, current-limiting circuits on all outputs, redundant power paths for critical payloads, internal redundancies, and single-point failure tolerance. Combines advanced power management with Maximum Power Point Tracking or S3R battery charge regulation. Used on missions including Intuitive Machines 2024 Lunar Mission, Sweden’s MATS satellite, ESA’s Arctic Weather Satellite, and Astroscale’s ELSA-M space debris removal service.
