Description
7796HC Linear Power Amplifier for High-Current Applications
The 7796HC Linear Power Amplifier is engineered for precision, power, and performance. Delivering up to 85A continuous at 13.5V DC and 200A peak in-rush current, it is a versatile, DC-enabled amplifier designed for advanced simulation and testing of ripple noise, surges, dropouts, and other disturbances in automotive, aerospace, and industrial electronics.
Versatility Meets Control
Operating in both controlled-voltage and controlled-current modes, the 7796HC provides a wide DC to 100+ kHz bandwidth, enabling four-quadrant functionality (source and sink). Whether driving highly reactive loads or managing power surges, it remains stable under all conditions. It’s your go-to amplifier for DC Conducted Immunity testing with high-current Equipment Under Test (EUTs).
Advanced Monitoring and Safety
With integrated LED indicators, soft-touch buttons, and a customizable LCD display, you get real-time visibility into peak voltage, current, and status. The 7796HC features robust protection circuits guarding against voltage fluctuations, overcurrent, temperature overloads, and ground-loop issues—ensuring safe, consistent operation.
