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.
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.
