Leo PCDU Evolution Engineering Model (EM) in the range < 1 kW for Earth Observation and Science satellites

Objective: To develop a reduced version of a new Power Conditioning and Distribution Unit intended to serve the needs of spacecraft with power requirements in the range of ~500W to &lt; 1 kW.

Background and justification: This activity aims at extending the competitiveness of the already consolidated LeoPCDU product for missions in the range of &lt; 1 kW, fully in line with the market requirement trends and the evolution observed in the products of Crisa’s competitors. The idea behind this modularity is to get the optimum power control and distribution unit (PCDU) architecture from the recurrent cost, electrical, mechanical, and thermal behavior points of view, as well as an optimum and modular easy to manufacture concept, easy to repair in case of need. Achievements and status: An Engineering Model has been manufactured for design validation. The engineering model unit has been tested including the Electrostatic Discharge &amp; Electromagnetic Compatibility tests. Benefits: The results of this activity consolidate Crisa’s position as a key PCDU supplier for low to medium power mission - 5 LeoPCDU-EVO.
