Technical Product Specification
Intel® Server Chassis SC5650 TPS Power Sub-system
Revision 1.2
Intel order number E39531-004

2.2.2.6 AC In-rush
AC line in-rush current does not exceed 55A peak for up to one-quarter of the AC cycle, after
which the input current is no more than the specified maximum input current. The peak in-rush
current is less than the ratings of its critical components (including input fuse, bulk rectifiers, and
surge limiting device).
The power supply meets the in-rush requirements for any rated AC voltage, during turn on at
any phase of AC voltage, during a single cycle AC dropout condition, as well as upon recovery
after AC dropout of any duration, and over the specified temperature range (T
op
).
2.2.2.7 Susceptibility Requirements
The power supply meets the following electrical immunity requirements when connected to a
cage with an external EMI filter that meets the criteria defined in the SSI document EPS Power
Supply Specification. For further information on Intel standards, please request a copy of the
Intel Environmental Standards Handbook.
Table 31. Performance Criteria
Level Description
A The apparatus should continue to operate as intended. No degradation of performance.
B The apparatus should continue to operate as intended. No degradation of performance
beyond spec limits.
C Temporary loss of function is allowed provided the function is self-recoverable or
restorable by the operation of the controls.
2.2.2.7.1 Electrostatic Discharge Susceptibility
The power supply complies with the limits defined in EN 55024: 1998 using the IEC 61000-4-
2:1995 test standard and performance criteria B defined in Annex B of CISPR 24.
2.2.2.7.2 Fast Transient/Burst
The power supply complies with the limits defined in EN55024: 1998 using the IEC 61000-4-
4:1995 test standard and performance criteria B defined in Annex B of CISPR 24.
2.2.2.7.3 Radiated Immunity
The power supply complies with the limits defined in EN55024: 1998 using the IEC 61000-4-
3:1995 test standard and performance criteria A defined in Annex B of CISPR 24.
2.2.2.7.4 Surge Immunity
The power supply was tested with the system for immunity to AC Ringwave and AC
Unidirectional wave, both up to 2kV, per EN 55024:1998, EN 61000-4-5:1995 and ANSI C62.45:
1992.
