Regenerative, Four-Quadrant Grid Simulator
The IT7900 series high-voltage models represent a new generation of programmable, four-quadrant grid simulators with 100% rated current source and sink capabilities, and energy feedback functionality. The energy generated by the device under test during testing can be completely recovered by the IT7900 high-voltage model equipment for direct on-site use, rather than being consumed as heat, providing users with a "green energy-saving" solution. Suitable for testing grid-connected products that inject energy into the grid, such as frequency changes, voltage transients, and DC injection tests of on-grid/off-grid photovoltaic inverters.
Touchscreen Design, Built-in Oscilloscope Function
The IT7900 high-voltage models are equipped with a new touchscreen design and an intuitive UI interface. The keyboard and knob design allows users to directly and quickly perform mode settings and waveform editing operations. The built-in digital oscilloscope function collects the time-domain signals of voltage and current, phase relationships, and performs waveform triggering functions. The oscilloscope sampling rate is up to 10us, and up to 6 oscilloscope waveforms can be displayed simultaneously. Users can perform instantaneous analysis without an oscilloscope and save the results in a timely manner.
Extensive Built-in Waveform Library
In addition to basic sine waves, the IT7900 high-voltage models offer a variety of built-in AC waveforms, such as triangle waves, sawtooth waves, square waves, trapezoidal waves, and clipped waves. Users can call these waveforms from the menu and display them on the LCD screen. Combined with the device's sequential programming function, continuous output of different waveforms can be combined to cope with complex power electronic disturbance tests.
