7800 Series High-power, high-precision, AC/DC linear power amplifiers
AE Techron’s 7800-Series AC power amplifiers are durable, four-quadrant, DC-enabled, low-noise, wide-bandwidth amplifiers.
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 optimized 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.
