lists and describes the electrical specifications for the 750 W AC-input power supply.
Electrical Specifications, 750 W AC-Input Power Supply
1
Description
Autoranging input with power factor correction
(PFC)
100 to 240 VAC (115/230 VAC nominal)
single-phase
11 A @ 100 VAC (max)
•
6 A @ 200 VAC (max)
•
47 to 63 Hz (50/60 Hz nominal)
Each chassis power supply should have its own
dedicated, fused-branch circuit:
For North America—15 A
•
For International—Circuits should be sized 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.
750 W
12 VDC @ 62 A
•
3.3 VDC @ 3 A
•
16 ms minimum (20 ms @ 60% load)
1122 BTU/hour (nominal)
1365 BTU/hour (max)
