13.3.1.4 Temperature Requirements
The power supply operates within all specified limits over the T
op
temperature range. All airflow
passes through the power supply and not over the exterior surfaces of the power supply.

Notes:
1. Under normal conditions, the exit air temperature shall be less than 65C. 68C is provided for absolute
worst case conditions and is expected only to exist when the inlet ambient reaches 60C.
2. T
op_rackped_900
condition only requires max altitude of 900m.
The power supply meets UL enclosure requirements for temperature rise limits. All sides of the
power supply with exception to the air exhaust side are classified as “Handle, knobs, grips, and
so on held for short periods of time only”.
13.3.2 AC Input Requirements
13.3.2.1 Power Factor
The power supply meets the power factor requirements stated in the Energy Star
®
Program
Requirements for Computer Servers. These requirements are stated below.
Table 91. Power Factor Requirements for Computer Servers
Output power 10% load 20% load 50% load 100% load
Power factor > 0.65 > 0.80 > 0.90 > 0.95
Tested at 230Vac, 50Hz and 60Hz and 115VAC, 60Hz
Tested according to Generalized Internal Power Supply Efficiency Testing Protocol Rev 6.4.3.

13.3.2.2 AC Inlet Connector
The AC input connector is an IEC 320 C-14 power inlet. This inlet is rated for 10A/250VAC.
13.3.2.3 AC Input Voltage Specification
The power supply operates within all specified limits over the following input voltage range.
Harmonic distortion of up to 10% of the rated line voltage does not cause the power supply to
go out of specified limits. Application of an input voltage below 85VAC does not cause damage
to the power supply, including a blown fuse.
