DESCRIPTION
The
Power
Supply
is constructed
on a
rectangular recessed
aluminum
chassis de-
signed for standard rack mounting.
All
major
components
and
controls are identified
by
symbol
numbers. Controls are also identified
by
name. Other components
are identified
by
symbol number where
possible.
Wiring and
connections
are accessible
from the
rear.
Ex-
ternal
connections
are
made
to a
multiple
contact
plug
located
on the back of the
chassis.
A
rotary
switch
and
meter jack
on the
front
panel
are
available for checking
the
output voltage
and
current,
and
the
cur-
rent
balance
of the Type 6336
regulator
tubes.
A
circuit breaker
on the
front
panel
turns
the supply on and off and
affords over-
load
protection.
If
desired,
the high voltage
may
be
switched remotely.
INSTALLATION
The
Power
Supply
has been
tested
and
inspected before being shipped,
and should
be
ready for operation
when
received
and
properly installed.
Unpack the unit
care-
fully
and
inspect
it for
any
damage that
may have
occurred during shipment.
Notify
the shipping company of any such damage
immediately.
The
unit
is furnished
with two Short
Mounting
Brackets,
P
-7772418-P16, firmly
secured
to
either
side
of the
chassis, per-
mitting it
to be
installed
in
any
General
Electric television cabinet rack,
Mounting
hardware is furnished
with each cabinet
rack.
Special Long Mounting
Brackets,
P
-7772418-P5,
are
available
on
separate
order
for installations
in
other
than
a
General
Electric rack.
When
using
these,
the Short Mounting
Brackets must
first
be
removed before the Long Mounting
Brackets
can
be
installed.
Use
the same mounting
hardware that secured
the Short
Brackets.
The
Power Supply should be
operated at
an
ambient cabinet
temperature
not to ex
-
2
ceed
50
C
(122 F).
A
maximum
of
55
C
(131
F) can be tolerated for
not
more
than
5%
of the annual
operating hours.
The
unit
dissipates
550
watts,
This
requires
cooling
by moving
air
at
98
cfm with room ambient
at
35
C
(95
F), to keep
temperature rise
below
10
C
(28
F).
The
Elementary Diagram,
Fig.
2,
shows
all
electrical
connections.
The
unit as shipped is wired for
117
volts
f
5%
input voltage. For nominal
110
volts
input, change the wire from E11-2
to
E11-3
and
E12
-B
to E12
-C. For
nominal
125
volts
input, change the wire from E11-2
to
E11-1
and
E12
-B
to E12
-A.
The
unit is designed
for
a
nominal
280
volts
d
-c
output voltage.
For remote plate voltage switching,
re-
move the jumper
between
terminals
4
and
5
of
Pl,
and
connect
the
remote switch wires
to
terminals
4
and
5
of
Pl.
A
low
current
switch
(about
1
amp) may
be
used, since it
is
only
required
to
energize relay
K2.
Centering voltage available at
J3 is
ad-
justable at
Rl.
If
centering voltage is not
