4300 Series Modular DC Electronic Loads

Modular DC Load for Charger Testing, LED Driver Testing, Solar Panel Testing, & More

The NH Research 4300 Modular DC Electronic Load series combine an advanced electronic load with the latest digitizing circuits that record both voltage and current waveforms. Once digitized, that information can be quickly processed to calculate an exceptionally wide range of precision measurements. This technique typically eliminates separate, single-function measurement instruments such as a DMM, DSO, MUX, and related cabling. In addition to greatly simplifying tester design, the tester-per-load functionality provides simultaneous testing on all loads, thereby significantly improving test speed and tester throughput.
