NH Research 9430 Regenerative 4-Quadrant AC Load Series

The NH Research Model 9430 Regenerative 4-Quadrant AC Loads is currently regulated, with selectable phase inputs/outputs 4-quadrant single, split, or three-phase programmable AC loads that come in eight sizes ranging from 4 to 96 kW. This device can simulate nearly any linear or nonlinear load and can transmit power back to the facility mains instead of letting it dissipate as heat. Its bi-directional capabilities significantly expand load simulation relative to 2 quadrant AC loads.

These loads include digital measurement systems that feature a high-resolution waveform digitizer that provides power analysis tools typically found in equipment such as digital multimeters or oscilloscopes. The 9430 provides user-defined waveforms, power and crest factor control, linear and non-linear AC loading, and many emulation modes. It is also capable of simulating the reverse current produced by inductive or capacitive loads, which returns power to the UUT (source) during the AC cycle.
