Appendix A Power Supply Specifications
1400 W AC-Input Power Supply
1400 W Power Supply AC Power Cords
Table A-10 lists the specifications for the AC power cords that are available for the 1400 W AC-input
power supply. These power cords plug into the 1400 W PEM (PEM-20A-AC+); not directly into the
power supply. The table includes references to power cord illustrations.
Note All 1400 W power supply power cords are 14 feet (4.3 meters) in length.
Note All 1400 W power supply power cords have an IEC60320/C19 appliance plug at one end.
AC-input frequency 50/60 Hz (nominal) (±3 Hz for full range)
Power supply output capacity 1400 W
Power supply output
• 15 A @ +1.5 V
• 2.5 A @ +3.3 V
• 27.4 A @ +50 V
Output holdup time 20 ms minimum
Heat dissipation 5976 BTU/hour (approx.)
Front panel LEDs
INPUT OK
• Green—Source AC voltage is OK. (Input voltage
is 85 VAC or greater.)
• Off—Source AC voltage falls below 70 VAC, is
not present, or the power supply is turned off.
FAN OK
• Green—Power supply fan is operating properly.
• Off—Power supply fan failure is detected.
OUTPUT FAIL
• Red—Problem with one or more of the DC-output
voltages of the power supply is detected.
• DC-output voltages within acceptable margins.
