Electronic/Electrical Requirements
The CBX 500 power supplies are auto-ranging. That is, they provide adequate power
to the switch when the input voltage is between the minimum and maximum level for
each type of power supply.
For either AC or DC input versions, the CBX 500 is powered by a minimum of two
power supplies. For some applications, you can add a third power for redundancy, in
the event of a circuit or power supply failure, as described in Table 2-1.
