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.
Small Signal Frequency Response:
DC - 300 kHz +0.0 to -1.0 dB
