Atec Solar-6552-1A - Manual

MODEL 6552-1A 100 watt Solid State AUDIO AMPLIFIER
for conducted audio frequency susceptibility testing
APPLICATION
The Model 6552-1A 100 watt Solid State Audio
Amplifier was specifically designed for use
with the Type 6220-1A Audio Isolation
Transformer in making conducted audio
frequency susceptibility tests as required by
MIL-STD-461A/462 and other EMI specifications.
DESCRIPTION
The Model 6552-1A Audio Amplifier has a wide
frequency response and is capable of providing
up to 100 watts at 1000 Hz into 2.4 ohms at low
distortion levels. Requires approximately 0.6 volt
signal input for maximum power output at 1000
Hz. Incorporates feedback circuit for flat response
within one dB from 30 Hz to 100 KHz at reduced
power levels.
The -3 dB points are 25 Hz and 120 KHz when
using the 6220-1A Transformer loaded with
0.6 ohm. Cleverly designed protective circuit
prevents damage due to transients, back EMF,
overload or overdrive. Designed for laboratory use
with portable case and conventional binding
posts spaced .75" for standard shielded lead and
double plug connections.
FEATURES
s Solid state.
s Up to 100 watts output.
s Wide frequency range.
s Low input impedance.
s No output transformer.
s Input and output protective circuits.
s Lightweight and portable.
