Specification
Nominal –48 VDC, –60 VDC
Operating range: –40.0 to –72.0 VDC
NOTE: If the input voltage from the DC power
source drops below -37.5 to -39.5 VDC, the
router automatically shuts down. During
automatic shutdown, the circuit remains active.
When the input voltage returns to –43.0 to
–44.00 VDC, the router automatically starts
up again and the system returns to normal
operation within 30 minutes. No operator
intervention is required.
Input 0: 47 A @ –48 VDC (nominal) (2256 W)
Input 1: 44 A @ –48 VDC (nominal) (2112 W)
Input 2: 50 A @ –48 VDC (nominal) (2400 W)
Input 3: 50 A @ –48 VDC (nominal) (2400 W)
