Intel® Server System SR1640TH TPS Power Sub-System
Revision 1.0 63
Intel order number: E94847-001
3.4.2 Input current
The maximum input current shall be 15A for each input voltage range as in below table.
Table 55. Maximum input current
Input voltage Input current Max power
100-132 VAC 8 A 450 Watts
180-264 VAC 4 A 450 Watts
3.4.3 Input current harmonics
The input current drawn on the power line shall not exceed the limits set by IEC-61000-3-2
and JEIDA MIT1 standards.
3.4.4 AC Line Transient Specification
AC line transient conditions are defined as “sag” and “surge” conditions. Sag conditions are
also commonly referred to as a “brown-out”. These conditions are defined as the AC line
voltage dropping below nominal voltage conditions. Surge refers to conditions when the AC
line voltage rises above nominal voltage.
The power supply meets the requirements under the following AC line sag and surge
conditions.

3.4.5 Susceptibility Requirements
The power supply meets the following electrical immunity requirements:
Table 58. Performance Criteria
Level Description
A The apparatus shall continue to operate as intended. No degradation of performance.
B The apparatus shall 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 can be
restored by the operation of the controls.
