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

7234

Single-phase, 2U, industrial amplifier/battery simulator

  • Bench-sized
  • Powered from 120V/230VAC
  • Source and Sink (4 quadrant)
  • Rugged Design
  • 3-Year, No-Fault Warranty

Key Performance Capabilities:

  • Drop outs and surges as fast as 1.2µs
  • Small signal response up to 1 MHz
  • 13.5 VDC at up to 28A
  • Field-selectable ±40V, 75V or 150V potential
 
 
 

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.

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.
