AAC Clyde Space’s small satellite PCDU (Power Conditioning and Distribution Unit) solutions have demonstrated impressive space-based capabilities stretching across a range of applications, gaining a market reputation for reliability, resiliency and performance. STARBUCK-MINI provides high power 28 V outputs and redundancy for power distribution as well as redundant command and control interfaces via CAN or RS422. Its innovative design combines COTS and radiation hardened components to optimizes the reliability and performance characteristics of the ITAR free system.

The STARBUCK-MINI adopts a modular design approach which enables easy customization. The adaptable system utilizes flexible add-ons to meet the required number of power output interfaces for payloads on each specific mission and can be quickly adapted to customer product specifications. Integration of interfaces for deployment mechanisms, magnetic torquers and other equipment can also be accomodated through the addition of custom modules.


With 1500 W system power, 28 V nominal bus and battery voltage with power converters for isolated auxiliary output. High-power 28V outputs & redundancy for power distribution, as well as FPGA based control & monitoring of all switches & interfaces through redundant CAN or RS422.


High-performance power solution for small satellite platforms. Modular design approach delivers scalability and easy tailoring of interfaces to mission requirements. With MPPT or S3R battery charge regulation for advanced power management.


Reliability and qualification levels suitable for many different mission types. COTS components with verified space performance combined with radiation hardened components. All outputs protected by Latching Current Limiters (LCLs) or Retriggerable LCLs (RLCLs). With support for redundant power supply to consumers.
