Intel order number: G11332-006 
The pass criteria include: No unsafe operation is allowed under any condition; All power supply 
output voltage levels to stay within proper spec levels; No change in operating state or loss of 
data during and after the test profile; No component damage under any condition. 
The power supply shall comply with the limits defined in EN55024: 1998 using the IEC 61000-4-
5:1995 test standard and performance criteria B defined in Annex B of CISPR 24. 
3.2.12 
AC Line Transient Specification 
AC line transient conditions shall be 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 shall meet the requirements under the following AC line sag and 
surge conditions.

3.2.13 Power 
recovery 
The power supply shall recover automatically after an AC power failure. AC power failure is 
defined to be any loss of AC power that exceeds the dropout criteria. 
 
3.2.14 
AC Line Isolation 
The power supply shall meet all safety agency requirements for dielectric strength.
 
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.
