Notes:
1. Maximum input current at low input voltage range shall be measured at 90VAC, at maximum load.
2. Maximum input current at high input voltage range shall be measured at 180VAC, at maximum load.
3. This requirement is not to be used for determining agency input current markings.
3.1.6.3 AC Line Isolation Requirements
The power supply shall meet all safety agency requirements for dielectric strength. Additionally,
power supply vendor must provide Intel
®
with written confirmation of dielectric withstand test
which includes: voltage level, duration of test, and identification detailing how each power
supply is marked to indicate that the dielectric withstand test had been completed successfully.
Transformers’ isolation between primary and secondary windings must comply with the
3000Vac (4242Vdc) dielectric strength criteria. If the working voltage between primary and
secondary dictates a higher dielectric strength test voltage, the highest test voltage should be
used. In addition, the insulation system must comply with reinforced insulation as per safety
standard IEC 950. Separation between the primary and secondary circuits, and primary to
ground circuits, must comply with the IEC 950 spacing requirements.
3.1.6.4 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 should 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 should meet the AC
dropout requirement over rated AC voltages and frequencies. A dropout of the AC line for any
duration should not cause damage to the power supply.

3.1.6.5 AC Line Fuse
The power supply should have one line fused in the single line fuse on the line (Hot) wire of the
AC input. The line fusing must be acceptable for all safety agency requirements. The input fuse
should be a slow blow type. AC inrush current must not cause the AC line fuse to blow under
any conditions. All protection circuits in the power supply should not cause the AC fuse to blow
unless a component in the power supply has failed. This includes DC output load short
conditions.
3.1.6.6 AC Inrush
Peak inrush current must not damage the PSU, or the input fuse must not blow under any
conditions of load, temperature, and input voltage, including repeated, rapid cycling of the power
