Power Sub-system
Table 110. 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 or 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

Supply Specification.
Level
A
B
C
2.5.7.8.1
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.
2.5.7.8.2
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.
2.5.7.8.3
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.
2.5.7.8.4
Surge Immunity
The power supply is 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.
The pass criteria include: no unsafe operation is allowed under any condition; all power supply
output voltage levels must stay within proper spec levels; no change in operating state or loss of
data during and after the test profile; no component damage under any condition.

Table 113. Performance Criteria
The apparatus shall continue to operate as intended. No degradation of
performance.
The apparatus shall continue to operate as intended. No degradationof
performance beyond spec limits.
Temporary loss of function is allowed provided the function is self-
recoverable or can be restored by the operation of the controls.
