2.2.2.3.4
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.
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.

AC Line Fast Transient (EFT) Specification
The power supply meets the EN61000-4-5 directive and any additional requirements in
IEC1000-4-5:1995 and the Level 3 requirements for surge-withstand capability, with the
following conditions and exception:
IEC1000-4-5:1995 and the Level 3 requirements for surge-withstand capability, with the
following conditions and exception:
These input transients do not cause any out-of-regulation conditions, such as overshoot
and undershoot, nor do they cause any nuisance trips of any of the power supply
protection circuits.

The surge-withstand test must not produce damage to the power supply.
The supply meets surge-withstand test conditions under maximum and minimum DC-output
load conditions.

2.2.2.5
AC Line Dropout/Holdup
An AC line dropout is defined to be when the AC input drops to 0VAC at any phase of the AC
line for any length of time. During an AC dropout, the power supply meets dynamic voltage
regulation requirements. An AC line dropout of any duration does not cause tripping of control
signals or protection circuits. If the AC dropout lasts longer than the hold up time, the power
supply will recover and meet all turn on requirements. The power supply meets the AC dropout
requirement over rated AC voltages, frequencies. A dropout of the AC line for any duration does
not cause damage to the power supply.
