2.3.2.2 AC Inlet Connector
The AC input connector shall be an IEC 320 C-14 power inlet. This inlet is rated for
10A/250VAC.
2.3.2.3 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.

Notes:
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.
2.3.2.4 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.

2.3.2.5 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).
2.3.2.6 AC Line Fuse
The power supply shall have one line fused in the single line fuse on the line (Hot) wire of the
AC input. The line fusing shall be acceptable for all safety agency requirements. The input fuse
