CM PCDU

Power Conditioning and Distribution Unit (PCDU)•power distribution,•GNC & RCS management,•standard I/O. The PCDU will include the following modules and functions :

•PCU : provides a 22-34V unregulated bus, based on a Maximum Power Point Tracking (MPPT) regulator topology. The input power will be delivered from a SA during sunlight periods, or from a Li-Ion battery during eclipses and when the SA power is lower than the power demand.

•PDU : distributes protected lines to DM, CM units & heaters, and commands pyro devices,

•RTU : assures GNC/RCS interfaces, delivers Standards I/O.
