Power Supply
The
power
supply
provides
power
to
the
7403
Terminal,
as
well
as
various
retail
peripherals
through
the
powered
connectors.
The
power
supply
is
controlled
by
a
logical
on/off
switch,
which
permits
it
to
be
disabled
through
software.
Other
features
include:
•
Auto
sensing
for
115
VAC/230
VAC
operation
•
Cooling
fan
Functionally,
the
terminal’s
ON/OFF
switch
controls
the
power
supply
control
logic
to
activate
the
power
supply.
This
switch
does
not
control
actual
AC
mains
voltage
applied
to
the
power
supply.
AC Input
The
power
supply
operates
with
the
following
voltage
ranges.

Note:
The

continuous
output
power
for
all
rails
(3.3V,
5V,
12V,
‐
12V,
5VSB,
24V)
should
not
exceed
265W.
Maximum Rated Output Power
The
maximum
rated
output
power
as
defined
as
the
continuous
load
is
265W.
However,
in
the
7403,
this
power
supply
will
be
limited
to
supporting
around
200W,
to
minimize
thermal
impact
to
the
system.
