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.

Notes:
1. Maximum input current at low input voltage range shall be measured at 90VAC, at maximum load.
2. Maximum input current at high input voltage range shall be measured at 180VAC, at maximum load.
3. This requirement is not to be used for determining agency input current markings.
13.3.2.4 AC Line Dropout/Holdup
An AC line dropout is defined as that 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 recovers and meets all turn on requirements. The power supply meets the AC dropout
requirement over rated AC voltages and frequencies. A dropout of the AC line for any duration
does not cause damage to the power supply.

13.3.2.4.1 AC Line 12VSBHoldup
The 12VSB output voltage stays 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).
13.3.2.5 AC Line Fuse
The power supply has one line fused in the single line fuse on the line (Hot) wire of the AC
input. The line fusing is acceptable for all safety agency requirements. The input is a slow blow
type. AC inrush current does not cause the AC line fuse to blow under any conditions. All
protection circuits in the power supply does not cause the AC fuse to blow unless a component
in the power supply has failed. This includes DC output load short conditions.
13.3.2.6 AC Line Transient Specification
AC line transient conditions are defined as “sag” and “surge” conditions. “Sag” conditions are
also commonly referred to as “brownout”; these conditions are defined as the AC line voltage
drops below nominal voltage conditions. “Surge” is defined to refer to conditions when the AC
line voltage rises above nominal voltage.
