Notes:
1 Maximum input current at low input voltage range should be measured at 90Vac at max load.
2 Maximum input current at high input voltage range should be measured at 180VAC at max load.
3 This is not to be used for determining agency input current markings.
4 Maximum rated input current is measured at 100 VAC and 200 VAC.
2.2.2.4 AC Line Transient Specification
AC line transient conditions are defined as “sag” and “surge” conditions. “Sag” conditions are
also commonly referred to as “brownout” and defined as AC line voltage drops below nominal
voltage conditions. “Surge” is defined as AC line voltage rises above nominal voltage
conditions. The power supply meets requirements under the following AC line sag and surge
conditions.

2.2.2.5 AC Line Fuse
The power supply has a 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 will not cause the AC line fuse to blow under any conditions. All protection circuits in the
power supply will not cause the AC fuse to blow unless a component in the power supply failed.
This includes DC output load short conditions.
