The G6000 series is a four-quadrant AC power supply featuring high precision, high power density, and high dynamic performance. As a source, it supports adjustment of three phases separately, while having LIST/PULSE/STEP and other programming functions to simulate the disturbance characteristics of grid voltage and frequency. It also has waveform editing, harmonic and inter-harmonic modes, able to simulate abnormal grid conditions and test the grid tolerance of the device under test (DUT). As a load, it has built-in AC load models to simulate different load characteristics.
