7200 Series
1 to 4 kVA General Purpose Linear Amplifiers
7224
The 7224 is a 4-quadrant industrial amplifier/battery simulator that is 2U tall and runs from single phase 120/230VAC. It features DC – 400 kHz bandwidth, controlled-current or controlled-voltage modes of operation, and has a wide range of field-configurable options.
It can be field-configured to run well into loads from 100 ohms to as low as 0.5 ohms. The 7224 can produce as much as 50 amps of current and as much as 158 volts, providing serious power for a wide range of applications and experiments. With its 90V/µS slew rate, it can accurately reproduce waveforms from DC to above 400 kHz.
7234
The 7234 provides up to 30A of long-term DC current with surges of up to 50A and can slew voltages at rates of up to 100V/us. It is load-tolerant and able to drive most inductive, capacitive, and resistive loads easily.
The 7234 is light enough to be hand-carried from one test location to another, rugged enough to tolerate being bounced around on a cart, and able to be powered from standard 120V/230V AC Wall power.

7800 Series
10 to 20 kW, DC to 60 kHz, Three-Phase
AE Techron’s 7800-Series AC power amplifiers are durable, four-quadrant, DC-enabled, low-noise, wide-bandwidth amplifiers. This combination of features and capabilities makes them a great choice for a large number of research and industrial applications.
7800 series amplifiers are a great solution if bandwidth and/or system noise is a problem. They are able to drive low-impedance loads at frequencies of up to 60 kHz. Because they utilize a linear circuit topology, AE Techron 7800 series amplifiers have no switching noise in their output and very low radiated EMI. This results in THD and noise floors that are much lower than what is possible with traditional switch mode amplifiers, making them ideal for applications that require either high precision or, because of sensitive measurements, cannot tolerate the radiated noise associated with switch mode amplifiers.
7800 series amplifiers are tough, both physically and electrically. 7800 series models have been used for conducting experiments on a Navy warship, controlling a magnetic field in a fusion experiment, and driving DUTs while absorbing back EMF when there is a failure.
The 7800 series is designed and built for applications where large surge currents or long duration power is needed. This makes them ideal for applications where power or duty cycle requirements are greater than is possible with consumer- or pro-audio grade amplifiers. Because power ratings are continuous, AE Techron amplifiers often produce between 4 and 8 times more power than a similarly rated consumer amplifier.
7800 Series amplifiers are modular and scalable. They are available in three standard power ranges: 10kVA, 15kVA and 20kVA. Within each power range, models are available that have been optimised for load impedances from 0.1 ohm to 8 ohms. Customized versions can be ordered with special amplifier configurations and/or with extra rack space to install additional equipment.
