Regenerative 4-Quadrant AC Grid Simulator
The IT7900 series are four-quadrant grid simulators with 100% of currentsource and sink and 88% energy recovery capability. The power generated by theDUT can be fed back to the grid,rather than being dissipated as heat. Suitable fortesting grid-connected products that inject energy into the grid, such as frequencychanges, voltage transients and anti-island testing of grid-connected photovoltaicinverters.

Touch screen，built-in oscilloscope functionIT7900 series is equipped with innovative touch screen, simple and intuitive UI interface, and the keyboard knob design allows users to directlyand quickly perform operations such as mode setting and waveform editing. The built-in digital oscilloscope function collects time-domainsignals of voltage and current, phase relationship and performs waveform trigger functions. The oscilloscope sampling rate is up to 10us, andup to 6 oscilloscope curves can be displayed at the same time. Users can perform instantaneous analysis without an oscilloscope and savethem in time.

Built-in various type of waveforms

In addition to the basic sine wave, the IT7900 series offers a variety of built-in AC waveforms such as triangle, sawtooth, square,trapezoidal and clipped. Users can recall through the menu and display the selected waveform on the LCD screen. Combined with the device’ssequence programming function, the continuous output of different waveforms can be combined to cope with complex power electronicdisturbance tests.
