brownout shall not blow the fuse. The power supply will tolerate a 3min ramp from 90VAC
voltage to 0VAC after the components have reached a steady state condition.
3.4.5.2 Voltage Interruptions
The power supply complies with the limits defined in EN55024: 1998 using the IEC 61000-4-
11:1995 test standard and performance criteria C defined in Annex B of CISPR 24.
3.4.6 AC Line Inrush
AC line inrush current will not exceed 40A peak for up to one-quarter of the AC cycle, after
which, the input current should be no more than the specified maximum input current. The peak
inrush current shall be less than the ratings of its critical components (including input fuse, bulk
rectifiers, and surge limiting device).
The power supply meets the inrush 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
op
). It is acceptable that
AC line inrush current may reach up to
60A peak for up to 1 ms.
3.4.7 AC Line Leakage Current
The maximum leakage current to ground for each power supply is 3.5mA when tested at
240VAC.
3.4.8 AC Line Fuse
The power supply has a single line fuse, on the Line (Hot) wire of the AC input. The line fusing
is acceptable for all safety agency requirements. The input fuse is a slow blow type. AC inrush
current will not cause the AC line fuse to blow under any conditions. All protection circuits in the
power supply will not cause the AC fuse to blow unless a component in the power supply has
failed. This includes DC output load short conditions.
3.4.9 Power Factor Correction
The power supply incorporates a Power Factor Correction circuit.
The power supply was tested as described in EN 61000-3-2: Electromagnetic Compatibility
(EMC) Part 3:
Limits- Section 2: Limits for harmonic current emissions, and meets the harmonic
current emissions limits specified for ITE equipment.
The power supply was tested as described in JEIDA MITI Guideline for Suppression of High
Harmonics in
Appliances and General-Use Equipment and meets the harmonic current
emissions limits specified for ITE equipment
3.5 Protection Circuits
Protection circuits inside the power supply will cause only the power supply’s main outputs to
shutdown. If the power supply latches off due to a protection circuit tripping, an AC cycle OFF
for 15 sec and a PSON
#
cycle HIGH for 1 sec shall be able to reset the power supply.
3.5.1 Over-Current Protection (OCP)
The power supply will have current limits to prevent the +3.3V, +5V, and +12V outputs from
exceeding the values shown in the following table. If the current limits are exceeded, the power
