1 Introduction
Congratulations on your purchase of the 7224 or
7226 AE Techron power amplifier—one of the most
precise power amplifiers ever produced for indus
-
trial applications and testing. The 7224 and 7226
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 ampli
-
fiers as well as its product service and support.
1.1 Features
The 7224/7226 is a single-channel linear amplifier
designed for use in demanding applications requir
-
ing low noise, low distortion, and accurate power
amplification from DC to 300 kHz. They feature:
•
Small-signal bandwidth of DC to 300 kHz.
• Continuous output of over 900 watts RMS at 4
ohms.
• 40 mSec pulses of up to 52 amperes peak into
a 0.5 ohm load.
• System output of over 3,600 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 amplifier from
input overloads, improper output connection
(including shorted and improper loads), over-
temperature, over-current, and supply voltages
that are too high or low.
•
Shipped ready to operate from 120-volt (±10%)
single-phase AC mains; 220/240-volt model
available on request.
