Description
Wide-ranging input with power factor correction.
Note Power factor correction is a standard feature on AC-input power supplies.
Power factor correction reduces the reactive component in the source
AC current, allowing higher power factors (0.90 minimum at loads equal
to or greater than 20 percent of maximum loads, and 0.95 minimum at
3200W maximum loads, at 115/230 VAC nominal AC input voltages)
and lower harmonic current components.
Low-line (115 VAC nominal)—85 VAC (min) to 132 VAC (max)
High-line (230 VAC nominal)—180 VAC (min) to 264 VAC (max)
17.6 A at 100 VAC (1570 W output)
17.6 A at 200 VAC (3200 W output)
50/60Hz nominal (47 to 63Hz full range)
Each chassis power supply should have its own dedicated, fused-branch circuit:
• North America—20 A.
• International—Circuits 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.
• For high-line operation, the power supply operates with the line conductor
wired to an source AC phase, and the Neutral conductor wired either to
a Neutral, single-phase power system, or to another source AC phase as
long as the net input voltage is in the range of 180 to 264 VAC.
For 55 VDC output—1560 W at 115 VAC; 3190 W at 230 VAC
For 3.3VDC output—10 W at 115 VAC; 10 W at 230 VAC
