• Four-quadrant operation (source and sink)

OVERVIEW

The 7794 is a powerful four-quadrant amplifier that offers up to 200 Ap power, DC – 100 kHz bandwidth, and controlled-current or controlled-voltage modes of operation. The 7794 works best into loads of 0.5 ohms or less. For greater voltage or current (up to 800 Ap) units can be combined in parallel or series.

Typically used when large currents are needed to drive very low impedances for long periods of time. Often used as a battery substitute for transient immunity testing requiring a battery as specified in EMC Test Standards for military, aviation and the automotive industries.
