2.3.2.5 AC Line Fuse
The power supply has a single line fuse on the line (hot) wire of the AC input. The line fusing is
acceptable for all safety agency requirements. The input fuse is a slow blow type. AC inrush
current will not cause the AC line fuse to blow under any conditions. All protection circuits in the
power supply will not cause the AC fuse to blow unless a component in the power supply has
failed. This includes DC output load short conditions.
2.3.2.6 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
).
2.3.2.7 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.
Table 55. 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.
