Application
4750 Series Electronic Loads are designed for testing applications that require a high-power and high-voltage plus measurement of UUT dynamic performance. The loads provide exceptional reliability combined with the inherent simplicity and safety of air cooling. The 4750 Loads are controlled through a LabVIEW soft-panel or an emPower^TM Test Executive enabled automatic test station. Typical power conversion products to be tested include higher-power DC supplies, telecom rectifiers, fuel cells and batteries.

Extended Internal Measurements
The 4750 Loads eliminate the need for separate external instruments to capture timing and other dynamic measurements during UUT turn-on and turn-off. This is accomplished by incorporating the task-essential features of a DMM, DSO and Transient Generator. With this built-in capability, the 4750 can rapidly generate engineering-characterization-like test information at fast test speeds with the additional benefit of cost savings from fewer measurement instruments, switches and interconnection wiring.

Complex Load Profile Playback
To facilitate ease of re-creating complex, precisely timed, multi-mode load profiles, a 100-step macro-recording capability allows capturing a dynamic sequence for later playback from within the Load. Additional complex profiles can be stored in a system controller library to be downloaded to the Load when required.
