1. Maximum input current at low input voltage range is measured at 90VAC, at max load.
2. Maximum input current at high input voltage range is measured at 180VAC, at max load.
3. This requirement is not used for determining agency input current markings.
4.1.5.2 AC Line Transient Specification
AC line transient conditions are defined as “sag” and “surge” conditions. “Sag” conditions are
also commonly referred to as “brownout,” and are defined as AC line voltage drops below
nominal voltage conditions. “Surge” is defined as AC line voltage rises above nominal voltage
conditions.
The power supply meets requirements under the following AC line sag and surge conditions.

4.1.5.3 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 22. 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.
