Which DCPS is specifically associated with BUS2 PMA?

The correct answer is DCPS4. This is specifically associated with the BUS2 PMA (Power Management Architecture) within the MQ-9 systems structure. Each DCPS (Data Concentrator Power Supply) has unique functions and relationships with various system components, and DCPS4 is designated to manage and distribute power relevant to the BUS2 architecture efficiently. This ensures that the systems connected to BUS2 receive the appropriate power level and management capabilities necessary for optimal performance. Therefore, recognizing the association between DCPS4 and BUS2 PMA is crucial for understanding how power distribution works in the aircraft's operational framework.
