Table 45 on page 104 lists the power specifications for the 3000 W DC power supply used
in EX8216 switches.
Specifications
Minimum operating voltage: –40 VDC
Nominal operating voltage: –48 VDC
Operating voltage range: –40 VDC through –72 VDC
NOTE: If the input voltage from the DC power source drops below –37.5 VDC through –39.5
VDC, the switching platform automatically shuts down. During automatic shutdown, the
circuit remains active. When the input voltage returns to –43 VDC through –44 VDC, the
switch automatically starts up again and the system returns to normal operation within 30
minutes. No operator intervention is required.
75 A maximum at nominal operating voltage (–48 VDC) for each input terminal.
3000 W
100 A
