AC Input Specifications

3.5.1

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.
Output power
Power factor 1600w
AC
Note: Tested at 230VAC, 50Hz and 60Hz and 115VAC, 60Hz
3.5.2

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.
Parameter
Voltage (110) 90 Vrms
Voltage (220) 180 Vrms
Frequency 47 Hz
Note:
1. Maximum input current at low input voltage range is measured at 90VAC, at max load.
2. Maximum input current at high input voltage range is measured at 180VAC, at max load.
3. This requirement is not to be used for determining agency input current markings.
3.5.3

AC Line Isolation Requirements

The power supply meets all safety agency requirements for dielectric strength. Transformers'
isolation between primary and secondary windings complies with the 3000VAC (4242VDC)
dielectric strength criteria. If the working voltage between primary and secondary dictates a
higher dielectric strength test voltage, the highest test voltage will be used. In addition the
insulation system complies with reinforced insulation per safety standard IEC 950. Separation
between the primary and secondary circuits, and primary to ground circuits, complies with the
IEC 950 spacing requirements.
3.5.4

AC Line Dropout/Holdup

An AC line dropout is defined to be when the AC input drops to 0VAC at any phase of the AC
line for any length of time. During an AC dropout the power supply meets dynamic voltage
regulation requirements. An AC line dropout of any duration does not cause tripping of control
signals or protection circuits. If the AC dropout lasts longer than the holdup time, the power
supply will recover and meet all turn on requirements. The power supply meets the AC dropout
