Feedback, full four-quadrant grid simulator<\/h2>\n

The IT7900E series represents a new generation of programmable, full four-quadrant grid simulators with 100% rated current source and sink capabilities, and provide energy return function. To be tested in the test of the energy generated by the IT7900E equipment can be completely recovered by the plant after direct utilization, rather than in the form of thermal energy consumption, to provide users with \"green energy-saving\" solutions. It is suitable for testing grid-connected products that inject energy into the power grid, such as grid-connected\/off-grid photovoltaic inverters for frequency changes, voltage transients and DC injection.<\/p>\n<\/div>\n

<\/div>\n

Master-slave parallel connection with power range up to 1MVA+<\/h2>\n
\n

 <\/p>\n

When users have higher power requirements, they can use the master-slave parallel function of the IT7900E series to increase the output current and power capacity.The IT7900E series can be paralleled up to 1MVA+ and can be easily paralleled without dismantling or installing cabinets.The IT7900E series has the master-slave paralleling function of equalizing the currents, and has its own synchronous ON\/OFF input and output signals, which guarantees the synchronization of paralleling. The IT7900E series not only retains all the functions but also has no loss of precision after paralleling. It makes the construction of power supply system faster, more flexible and more economical, whether it is a single test or system construction, it can be easily satisfied.<\/p>\n

 <\/p>\n

Touch screen design with built-in oscilloscope function<\/h2>\n

 <\/p>\n

The IT7900E series is equipped with a new touch screen design, a simple and intuitive UI interface, and a keyboard knob design that allows users to perform operations such as mode setting and waveform editing directly and quickly. The built-in digital oscilloscope function acquires time domain signals of voltage and current, phase relationship and performs waveform triggering and other functions. The oscilloscope sampling rate is up to 10us, and up to 6 oscillographic curves can be displayed at the same time, allowing users to perform instantaneous analysis without an oscilloscope and save it in time.<\/p>\n

\"20210726160431431\"<\/p>\n

Built-in rich waveform library<\/h2>\n

 <\/p>\n

In addition to the basic sine wave, the IT7900E series offers a variety of built-in AC waveforms such as triangle, sawtooth, square, trapezoidal, and clipped waveforms. The user can call up and display the selected waveforms on the LCD screen through the menu. Combined with the device's sequence programming function, continuous outputs of different waveforms can be combined to cope with complex power electronic perturbation tests.<\/p>\n
