Aetec 7794 High Current Linear Amplifier: Engineered for Demanding Industrial Applications
The Aetec 7794 Industrial Amplifier is a high-performance, four-quadrant linear amplifier designed specifically for low impedance and high-current testing environments. With output capabilities reaching up to 200 Ap and ±95 V DC, this amplifier delivers powerful performance across a DC to 150 kHz bandwidth, making it ideal for EMC testing, transient immunity validation, and military-grade endurance testing.
Built to support continuous operation, the 7794 offers 60A continuous current at 13.8V DC, with an in-rush capacity of up to 200A. Whether your application requires precise control over voltage or current, this model provides a field-selectable operation mode to ensure flexibility across various testing setups. It is optimized for loads of 0.5 ohms or lower and offers four-quadrant capability to both source and sink energy, critical in simulation of real-world operating conditions.
