3.2.6.2 AC Inlet Connector
The AC input connector shall be an IEC 320 C-14 power inlet. This inlet is rated for
10A/250VAC.
3.2.6.3 AC Input Voltage Specification
The power supply must operate within all specified limits over the following input voltage range.
Harmonic distortion of up to 10% of the rated line voltage must not cause the power supply to
go out of specified limits. Application of an input voltage below 85VAC should not cause
damage to the power supply, including a blown fuse.

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.
3.2.6.4 AC Line Isolation Requirements
The power supply should 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 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 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.
