4000 W AC-Input and DC-Input Power Supplies
Branch circuit requirement (AC-input)
Each chassis power supply should have its own
dedicated, fused-branch circuit:
dedicated, fused-branch circuit:
•
For North America—30 A
•
For International—Circuits should be sized
according to local and national codes
according to local and national codes
•
All AC power supply inputs are fully isolated.
–
Source AC can be out of phase between
multiple power supplies in the same chassis,
which means that PS1 can be operating from
phase A and PS2 can be operating from
phase B.

–
Source AC can be out of phase between AC
inputs on power supplies that are equipped
with multiple AC inputs, which means that
power cord 1 can be plugged into phase A and
power cord 2 can be plugged into phase B.

(operating range: –55 VDC to –72 VDC)
(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.
