Table 2
Electrical Specifications, 750 W AC-Input Power Supply
Specification
Description
AC-input type
Autoranging input with power factor correction
(PFC)
AC-input voltage
100 to 240 VAC (115/230 VAC nominal)
single-phase
AC-input current
•
11 A @ 100 VAC (max)
•
6 A @ 200 VAC (max)
AC-input frequency
47 to 63 Hz (50/60 Hz nominal)
Branch circuit requirement
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.
Power supply output capacity
750 W
Power supply output
•
12 VDC @ 62 A
•
3.3 VDC @ 3 A
Output holdup time
16 ms minimum (20 ms @ 60% load)
BTU (total output)
1
1.
1000 BTU/hour = 293 W
1122 BTU/hour (nominal)
1365 BTU/hour (max)
