4000 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)
DC-input current
Power supply output
capacity
• –60 VDC @ 29 A for nominal –60 V battery backup system
(operating range: –55 VDC to –72 VDC)
Note The 4000 W DC-input power supply requires two source
DC-inputs to be connected; it cannot operate with only one
positive (+)/negative (-) source DC terminal pair installed.
40 A per each DC input (three inputs)
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.
• 4000 W with three inputs active
• 2700 W with two inputs active
Note The 4000 W power supply cannot operate with only one source
DC-input connected.

• 5 A @ + 5 VDC
• 12 A @ +12 VDC
• 90.63 A (three inputs) or 59.68 A (two inputs)
@ +42 VDC
Note The 4000 W power supply cannot operate with only one source
DC-input connected.
Accepts 4 AWG copper conductors. Actual size of the wire needed is
determined by the installer or local electrician.
