Introducing the AE Techron 7234 Audio Bandwidth+ Amplifier and Battery Simulator
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.
Protection circuitry protects the amplifier from input overloads, improper output connection (including shorted and improper loads), overtemperature, over-current, and supply voltages that are too high or low.
Shipped ready to operate from 120-volt (±10%) single-phase AC mains; 220/240-volt model available on request.
Key Benefits
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.
