The NH Research 4600-12kW is a 12 kW AC electronic load for high-demand test applications requiring linear and non-linear AC loading simulation. It delivers programmable versatility across a 50–350 V operating range with maximum current capability of 120 A, enabling realistic evaluation of AC-powered equipment behavior under diverse field conditions. The instrument supports seven emulation modes—Constant Current, Constant Resistance, Constant Voltage, Constant Power, Short Circuit, Unity Power Factor, and Complex Non-Linear Waveform—with independently programmable crest factor and power factor control.
