Specification Description
Table A-22 2700 W DC-Input Power Supply Specifications
Specification Description
DC-input voltage
• –48 VDC @ 37 A for nominal –48 V battery backup system
(operating range: –40.5 VDC to –56 VDC)
• –60 VDC @ 29 A for nominal –60 V battery backup system
(operating range: –55 VDC to –72 VDC)
DC-input current (per DC
input)
• 43 A @ –40.5 VDC
• 37 A @ –48 VDC
• 29 A @ –60 VDC
Note For multiple DC input power supplies, each DC input must be
protected by a dedicated circuit breaker or a fuse. The circuit
breaker or the fuse must be sized according to the power supply
input power rating and any local or national electrical code
requirements.
Power supply output
capacity
• 1350 W maximum (–48 to –60 VDC, with one DC input)
• 2700 W maximum (–48 to –60 VDC, with two DC inputs)
