1 Introduction
Congratulations on your purchase of the 7224 AE
Techron power amplifier—one of the most precise
power amplifiers ever produced for industrial ap
-
plications and testing. The 7224 amplifiers are built
and tested to the most stringent quality standards
for long life and outstanding performance. The AE
Techron brand is known throughout the world for
its robust precision amplifiers as well as its product
service and support.
1.1 Features
The 7224 is a single-channel linear amplifier de
-
signed for use in demanding applications requir-
ing low noise, low distortion, and accurate power
amplification from DC to 300 kHz. They feature:
•
Frequency bandwidth of DC to 300 kHz at
rated power.
•
Continuous output of over 1,100 watts RMS at
4 ohms.
• 40 mSec pulses of up to 52 amperes peak into
a 0.5 ohm load.
• System output of over 4,000 watts or over 200
amperes maximum is possible with multiple,
interconnected amplifiers.
• Efficient design and light weight chassis materi-
als allow amplifier to occupy only 2U height,
and weigh only 41 lbs.
• Robust, linear power supply results in extreme-
ly low noise; bi-level switch design limits heat
dissipation to output devices.
• Protection circuitry protects the AE Techron
7224 from input overloads, improper output
connection (including shorted and improper
loads), over-temperature, over-current, and
supply voltages that are too high or low.
• 7224 with “P” option offers precision control of
output offset, DC drift and gain linearity.
•
Shipped ready to operate from 120-volt (±10%)
single-phase AC mains; 220/240-volt model
available on request.
