Power Supply
Power Supply
The station Power Supply is mounted in
the
upper half of the cabinet behind
the
Power Amplifier (PA). The Standard Power Supply is a ferro-resonant type that
operates from
a
nominal
110 volt, single-phase,
60
Hz AC
power
source.
Options
are
available for
220 Vac, 50
Hz
operation, as
well
as
different power levels and
DC
supplies
on selected models.
The Power Supply
accepts an
AC
input voltage
and generates
DC
voltages for the
station. Each
PA
requires
a
dedicated Power Supply.
Low
power stations require
one
Power Supply and high power stations require two Power Supplies.
A
Battery Charger Power
Supply
is also available.
The following available power supply options
are:
O
110
or
220
Vac inputs
0
50
or 60
Hz
operating frequencies
O
250, 500, 575, or 675 watts
0
various output voltages
Refer to the
Power Supply manual for
a more detailed explanation
of power
supplies and options.
Standard Power Supply
The Standard Power Supply receives
AC
power from the
Junction Box via
the
line
cord. Refer to
Figure
1-36.
The Standard Power Supply provides high current
A+
to the
PA (if
installed) and two unfiltered +13.8
Vdc (A++)
outputs to the station
RF
Tray.
The Standard Power Supply provides
the
following
features:
0
output regulation
oa filtering
short circuit protection
current
limiting
a
overvoltage protection
Battery Charger Power Supply
The Battery Charger Power Supply
receives
AC
power from the
Junction Box
via
the line cord. Refer to
Figure
1-37.
The battery charger circuitry permits
the station
to operate from
AC
power normally, but provides continued operation from
external batteries (emergency power)
if
the
AC
power should fail. The Power
Supply
provides high current
A+
to the
PA (if
installed) and two
+13.8
Vdc
unfiltered outputs to the
RF
Tray.
