■ three-phase voltage independently adjustable
■ Three-phase power adjustable phase
■ input PFC circuit, there is EMI filter, AC output waveform is pure, small DC output ripple, small interfering
■ The use of advanced direct digital frequency synthesizer (DDS) waveform generation technology, high frequency stability, continuity
■ output voltage, current limit function
■ output voltage, frequency synchronization TTL signal
■ STEP mode once the group perform 30 different voltage, frequency gradients, and can do continuous cycle test 999999
■ LVRT mode specifically for grid-connected inverters do LVRT test
■ Built-in a variety of different harmonic distortion waveform output for each mode can be called directly
■ You can also customize edit different harmonic content of the output waveform distortion download via PC harmonics editor
■ The analog voltage periodic interrupt, dips, a variety of complex waveforms instantaneous rise and variation, to meet the user to do a variety of test
■ High current crest factor for the surge current testing
■ with 10 memory can be commonly used parameters (voltage, frequency) are stored for easy call when using
■ high accuracy, test applies a current half-sine and similar various waveforms with DC component
■ Provides DC output with grid inverter constituted cycle path, eliminating the need for load and greatly reduce energy loss
