Features

 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 materials allow

amplifier to occupy only 2U height and weigh only 41 lbs.

 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.

The AE Techron 7224 amplifier is a 1
kVA, DC-enabled unit that provides
exceptional versatility and value. It
features DC to 300 kHz bandwidth and
offers a wide range of field­configurable options. A single 7224
can output a 40 mSec pulse with up to
52 amperes peak current. In
continuous operation, a 7224 can
provide 1,100 watts RMS of output
power. If more current or power is
needed, up to four amplifiers can be
combined in series or parallel and
operate as a single system.

The 7224 can operate in either voltage
or current mode and can be
configured by the customer for high­voltage/low-current, medium voltage
and current, or low-voltage/high­current applications. It provides very
low noise and fast slew rates, and can
safely drive a wide range of resistive,
inductive loads.

The 7224 is typically used to create
waveforms found in EMC standards
like CS2009, DO-160, MIL STD 461,
and as a gradient amplifier for very
small bore, high-gain MRI and NMR
systems.

Performance

Testing was done at 100 Hz.
Continuous DC power levels are
lower. See DC Specifications chart.

7224P accuracy was measured when
driven into a 10-ohm load with
between 0.1VDC and 6VDC or
between 0.2VAC and 5VAC presented
at its inputs.
