1.6.9 Power Distribution Unit
The Power Distribution Unit (PDU) receives DC input and supplies power via
dedicated circuit breakers to each component in the MCSC system. Each of the
breakers has a three-position switch: ON, OFF or TRIPPED. The single alarm
output connected to each breaker is normally closed, and goes open when a
breaker is tripped.
