Efficiency
The power supply has a minimum efficiency of 75% at maximum load and over an 90-264VAC
line voltage range to guarantee proper power supply cooling while mounted in the system.
line voltage range to guarantee proper power supply cooling while mounted in the system.
2.3.2.3
AC Input Voltage Specification
The power supply operates within all specified limits over the following input voltage range, as
shown in following table. Harmonic distortion of up to 10% of rated AC input voltage will not
cause the power supply to go out of specified limits. The power supply powers off at or
after/below 75VAC +/-5VAC range. The power supply starts up at or before/above 85VAC +/-
4VAC. Application of an input voltage below 85VAC does not cause damage to the power
supply, including a fuse blow.

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 is not to be used for determining agency input current markings.
4
Maximum rated input current is measured at 100VAC and 200VAC.

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 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 meets the requirements
under the following AC line sag and surge conditions.
