Power Distribution Unit 
The Power Distribution Unit (PDU) receives DC input and supplies power via dedicated circuit 
breakers to each component in the MC-Series System. Each of the thirteen 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.
