2.4 Output Protection
Each DC output is protected from over voltage, over current and short circuit. The
following sections include the details for these protection mechanisms.
following sections include the details for these protection mechanisms.
2.4.1 Over voltage Protection
The overvoltage sense circuitry and reference reside in packages that are
separate and distinct from the regulator control circuitry and reference. No
single point fault is able to cause a sustained overvoltage condition on any
or all outputs. The power supply provides latch-mode overvoltage
protection defined as:
separate and distinct from the regulator control circuitry and reference. No
single point fault is able to cause a sustained overvoltage condition on any
or all outputs. The power supply provides latch-mode overvoltage
protection defined as:
+5V output is between 5.74V to 7V
+12V output is between 13.4V to 15.6V
+3.3V output is between 3.76V to 4.8V
+12V output is between 13.4V to 15.6V
+3.3V output is between 3.76V to 4.8V
2.4.2 Over Current Protection
The power supply
DC
outputs are protected from supplying output current
above the maximum ratings defined in Table 3, and when output power is
between
between
120%~180%.
With the exception of the
5VSB
output, all
DC outputs
are
latched
off in
the
event of
an
over-current event
on
any
of
the
DC
outputs.
In
the
event
of
a short
circuit
on
any
output
,
except
the
5VSB
rail
,
all
outputs
are
disabled and
remain
disabled
until
the
power
supply is powered
off back
on. The 5VSB rail will recover upon removal of the over current condition.
2.4.3 Short-circuit Protection
The power supply DC outputs are protected from damage due to faults,
when any output shorts to ground. In the event of a short circuit on any
output, all outputs shall be disabled and remain disable until the power
supply is powered off and back on. The +5VSB rail will recover upon
supply is powered off and back on. The +5VSB rail will recover upon
removal of the over current condition.

3.1 AC Connector
The AC input receptacle is an IEC 320 type or equivalent. In lieu of a dedicated
switch, the IEC 320 receptacle may be considered the mains disconnect.
