3.4.1 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.

3.4.2 Susceptibility Requirements
The power supply meets the following electrical immunity requirements:
Table 13. 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.
3.4.2.1 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.Tested to
meet the level 3 requirement.
