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.
