AC Input Specifications

3.5.1

Power Factor

The power supply must meet the power factor requirements stated in the Energy Star
for Computer Servers. These requirements are stated below.
Output power
Power factor
Tested at 230Vac, 50Hz and 60Hz and 115VAC, 60Hz
3.5.2

AC Input Voltage Specification

The power supply must operate within all specified limits over the following input voltage range. Harmonic
distortion of up to 10% of the rated line voltage must not cause the power supply to go out of specified limits.
Application of an input voltage below 85VAC shall not cause damage to the power supply, including a blown
fuse.
PARAMETER
Voltage (110)
Voltage (220)
Frequency
1. Maximum input current at low input voltage range shall be measured at 90VAC, at max load.
2. Maximum input current at high input voltage range shall be 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 shall meet all safety agency requirements for dielectric strength. Transformers' isolation
between primary and secondary windings must comply 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 should be used. In addition the insulation system must comply with reinforced insulation
per safety standard IEC 950. Separation between the primary and secondary circuits, and primary to ground
circuits, must comply 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 must meet dynamic voltage regulation requirements.
An AC line dropout of any duration shall not cause tripping of control signals or protection circuits. If the AC
dropout lasts longer than the hold up time, the power supply should recover and meet all turn on requirements.
The power supply shall meet the AC dropout requirement over rated AC voltages and frequencies. A dropout
of the AC line for any duration shall not cause damage to the power supply.
3.5.4.1 AC Line 12VSBHoldup
The 12VSB output voltage should stay in regulation under its full load (static or dynamic) during an AC dropout
of 70ms min (=12VSB holdup time) whether the power supply is in ON or OFF state (PSON asserted or de-
asserted).
