POWER SOURCES
The TW1000A amplifier operates
direct from any 28V negative ground
high current power source. Two
separate 110/230V, 50/60Hz rack
mounted power supplies are
available. The PS500 Is rated at 50A
output and will operate the TW1OOOA
at 1000W PEP in SSB service or
500-600W FSK. The PS1000 is rated
at 100A and will operate the amplifier
at a continuous 1000W (average)
power output in FSK or similar modes
with 25A reserve capability for the ex-
citer or other equipment.
TECHNICAL DESCRIPTION
Each of the two TW1 OOOAplug-in
modules uses two separate push pull
broadband amplifiers and a combiner.
The amplifiers are mounted on each
side of the module on massive heat-
sinks. A fan is mounted on the rear of
the module and is activated by
separate thermostats on each heat-
sink. The combined output of the two
modules pass through the high perfor-
mance harmonic fiiters and a VSWR
bridge which supplies the ALC
voltage to control the exciter drive
level.
SITOR ARQ OPERATION
The TW1 OOOAis supplied as standard
with high speed antenna relay and
control circuitry for SITOR ARQ
·service.
