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.
2.2.3.4 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 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.

2.2.3.5 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 fuse 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 do not cause the AC fuse to blow unless a component in
the power supply has failed. This includes DC output load short conditions.
2.2.3.6 AC Line Leakage Current
The maximum leakage current to ground for each power supply is 3.5mA when tested at
240VAC.
2.2.3.7 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 is defined as the AC line voltage
dropping below nominal voltage conditions. “Surge” is defined to refer to conditions when the
AC line voltage rises above nominal voltage.
The power supply meets the requirements under the following AC line sag and surge conditions.
