Introducing the AE Techron 7234 : Up to 50 Ap/158 Vp, DC to 250 kHz, Single-Phase

The 7234 is a capable, versatile, and reliable EMC lab partner.

This powerful amplifier/battery simulator provides up to 28A of long-term DC current with surges of up to 50A and can slew voltages at rates of up to 100V/µs.

It is load-tolerant, able to drive most inductive, capacitive, and resistive loads easily. The feature set of the 7234 allows it to meet or exceed the requirements of 1000+ Automotive and Aviation DC Conducted Susceptibility Standards Tests.

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. These features, along with the 7234s powerful performance, make it possible to turn virtually any bench or desk into a competent test location.
