5.2.4.1 AC Input Voltage Specification
The power supply operates within all specified limits over the following input voltage range (see
the following table). The power supply shall power off if the AC input is less than the 75 VAC+/-5
VAC range. The power supply operates properly starting at 85 VAC +/- 4 VAC input voltages.

Notes:
1
Maximum input current at low input voltage range shall be measured at 90 VAC at maximum load.
2
Maximum input current at high input voltage range shall be measured at 180 VAC at maximum load.
3
This requirement is not to be used for determining agency input current markings.
5.2.4.2 Efficiency
The power supply has a recommended minimum efficiency of 85% at maximum load and over
the specified 230 VAC voltage.
5.2.4.3 AC Line Fuse
The power supply shall have a single line fuse on the line (Hot) wire of the AC input. The input
fuse shall be a slow blow type. AC in-rush current shall not cause the AC line fuse to blow under
any conditions. No protection circuits in the power supply shall cause the AC fuse to blow
unless a component in the power supply has failed. This includes DC output load short
conditions.

5.2.5.1 Output Connector
The power supply provides card edge fingers, which mate to a female connector located on the
power distribution board (PDB). This blind mating type connector connects the power supply’s
output voltages and signals.
