The NH Research 9430 Series 4 quadrant regenerative AC loads are current regulated with selectable phase inputs and outputs and an integrated digital waveform measurement system. In sink mode, power is not dissipated as heat, but returned to the grid. The 9430 can simulate almost any linear or non-linear load.
The most unique feature of the 9430 AC load is its ability to operate in all 4 quadrants. This bi-directional capability greatly enhances AC load simulation compared to 2 quadrant AC loads. More specifically, the AC Load 9430 allows to generate the reverse current caused by inductive or capacitive loads (low power factors); namely, sending energy back to the UUT (source) during part of the AC cycle. In this way, the 9430 precisely maps the real electrical reactive power flows.
The advanced HIVAR design provides reactive loading without derating and allows testing of a high input reactive load without the usual derating in actual power (Watts) typically required with conventional loads.
