The PM contains the power input connector, main breaker, and all active circuitry for power distribution of a power bus.
The Power Module:
Soft starts the chassis on power up
Filters noise and power disturbances from the power feeds
Monitors the power draw of the chassis and shuts down a branch circuit in the event of a power fault
