Power Distribution Unit

Assembly

Switched power bus that takes battery power and feeds the flight computers, valve drivers, actuators and pyro circuits; two run in parallel so a single box failure never dark-buses the stage. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.

Power Distribution Unit parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Bare PCB 4× Bus, switching and control boards
2 Microcontroller 2× Load monitoring and control
3 Relay 32× Solid-state and EM load switches
4 SMD Passive (R/C/L) 2400× Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board.
5 Connector 48× Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering.
6 Wire Bundle 1× Internal box wiring
