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.
Testing was done at 100 Hz. Continuous DC power levels are lower. See DC Specifications chart for test conditions.
Frequency Response, DC – 300 kHz (1 watt): +1.0 to -1.5 dB Slew Rate: 100+ V/µSec Unit to Unit Phase Error: ±0.1 degrees at 60 Hz Output Impedance: 4.4 mOhm in Series with 0.43 µH Phase Response (10 Hz – 10 kHz) : ±5 degrees plus 600 nsec propagation delay

AC Output
Note: Testing performed into resistive loads as specified. Performance reported is typical into the specified load up to 20 kHz frequency levels. Performance may be affected when operating into highly reactive loads or above 20 kHz, reducing maximum voltage, current and power output. *Testing not performed. **Maximum 45 minutes of continuous operation. Numbers provided are preliminary.
