AC In-rush
AC line in-rush current does not exceed a 50A peak, cold start @ 20 degrees C and no damage
@ hot start for up to one-quarter of the AC cycle, after which, the input current is no more than
the specified maximum input current at 264Vac input. 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

AC Line Surge
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.
Pass criteria includes: No unsafe operation allowed under any conditions; all power supply
output voltage levels must stay within proper specification levels; no change in operating state
or loss of data during and after the test profile; no component damage under any conditions.

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.
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.
