There are 2-types of programmable dc electronic loads in this general-purpose, medium-to-high-power electronic load family. The 4700 is a relatively low-voltage electronic load (120V) with high-current capability. The High-Voltage DC Electronic Load (4760 Series) is a high-voltage electronic load (600V).
The High-Current DC Electronic Load (4700 Series) is used in a wide variety of applications that involve automated testing of power conversion device outputs to simulate real-world loading conditions. Such devices include DC power supplies, telecom rectifiers, and traction batteries.
Extended Internal Measurements
The High-Current DC Electronic Load eliminates 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 4700 DC Electronic Load can rapidly generate engineering-characterization-like test information at fast test speeds. An additional benefit is 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 for download to the electronic load when required.
