Output
Protection
|
A
short
circuit
placed
on
any
dc
output
(between
outputs
or
between
|
an
output
and
de
return)
latches
all
de
outputs
into
a
shutdown
state
|
with
no
damage
to
the
power
supply.
|
If
an
overvoltage
fault
occurs
(internal
to
the
power
supply),
the
|
power
supply
latches
all
de
outputs
into
a
shutdown
state
before
any
|
output
exceeds
130%
of
its
nominal
value.
|
If
either
of
these
shutdown
states
is
actuated,
the
power
supply
|
returns
to
normal
operation
only
after
the
fault
has
been
removed
and
|
the
power
switch
has
been
turned
off
for
at
least
ten
seconds.
| Voltage Sequencing
|
At
power-on
time,
the
output
voltages
track
within
50
milliseconds
of
|
each
other
when
measured
at
the
50%
points.
|
Power
Supply
Connectors
|
The
power
supply
provides
two
4-pin
connectors
for
internal
fixed
|
disk
drives.
These
connectors
can
be
extended
to
provide
power
to
|
more
than
one
internal
drive
as
long
as
the
total
power
does
not
|
exceed
the
specifications
shown
in
Figure
1-6
on
page
