Functional Description
Kewell G9000NProgrammable bidirectional communication source carrier systemIt has flexible operating modes, supports AC, DC, AC+DC output modes, and can independently set amplitude, frequency, phase, etc. Its output has multiple operating modes such as step, gradient, pulse, harmonic superposition/interharmonic mode, high and low voltage ride through, and feedback AC load; Programming data can be saved and supports import and export. In this mode, the output voltage, phase, amplitude, and frequency values can be set, with a minimum step size of 0.01V and 0.01Hz. The output mode can be set to three-phase linkage/three-phase independence/single-phase setting. Three phase linkage has the same voltage amplitude for each phase and a phase angle difference of 120 °;

LIST/PULSE mode
Equipped with multiple programming output modes such as LIST and PULSE, the PULSE mode provides single step or continuous voltage fluctuations, used to simulate power interference such asTransient voltage drop, instantaneous high voltage, gradual voltage drop, etc; LIST mode allows for the editing of more complex test waveforms, supporting 10 sets of work steps for editing. Each set can have 20 sequences, and the work steps can be set in a loop. At the same time, the waveform can contain both AC and DC, almost forming all desired signal waveforms. It can simulate various waveforms of voltage transients, interruptions, and variations.
High and low pressure crossing
G9000N Programmable Bidirectional AC Source Load SystemEquipped with high penetration, low penetration, and high low penetration joint testing functions, it can achieve single-phase, two-phase, three-phase and other crossing tests;

Harmonic mode/Interharmonic mode
In harmonic superposition mode, the harmonic amplitude of each voltage can be set to simulate abnormal power grid environments and test the power grid tolerance of the tested equipment.(2-100th harmonic superposition, can simultaneously superimpose 99 types of harmonics)
