The High Voltage DC Electronic Loads (4760 Series) are designed for testing applications that require high-voltage plus an exceptionally wide range of measurements, including product dynamic performance. The electronic loads provide superior reliability derived from the inherent simplicity and safety of air cooling. Automated testing may be PC-controlled either through NH Research’s emPower™ test executive or user-written test programs in LabVIEW, LabWindows/CVI or in any programming language which supports IVI Drivers. Typical power conversion products to be tested include higher-power DC supplies, telecom rectifiers, fuel cells and batteries.


Extended Internal Measurements

The High Voltage DC Electronic 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 4760 DC Electronic Load 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 electronic load. Additional complex profiles can be stored in a system controller library to be downloaded to the electronic load when required
