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.
2.2.2.4 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 holdup 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.

2.2.2.5 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).
2.2.2.6 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
shall be a slow blow type. AC inrush current shall not cause the AC line fuse to blow under any
conditions. All protection circuits in the power supply shall not cause the AC fuse to blow unless
a component in the power supply has failed. This includes DC output load short conditions.
2.2.2.7 AC Line Transient Specification
AC line transient conditions shall be defined as “sag” and “surge” conditions. “Sag” conditions
are also commonly referred to as “brownout”, these conditions will be defined as the AC line
voltage dropping below nominal voltage conditions. “Surge” will be defined to refer to conditions
when the AC line voltage rises above nominal voltage.
The power supply shall meet the requirements under the following AC line sag and surge
conditions.
