Feedback AC/DC loads

As a new feedback type AC electronic load, IT8200 series feedback efficiency is as high as 88%, whether in AC mode or DC mode, can be the object to be tested in the test of the energy generated by the high amount of recycling and then directly utilized in the plant, rather than in the form of heat consumption, to provide users with "green energy-saving This provides users with a "green and energy-saving" solution.

Single-phase, three-phase, and reverse-phase operation modes

The IT8200 series has very flexible operation modes, single-phase, three-phase and inverted mode can be selected through the panel menu. 350V equipment in inverted mode, the user can obtain a maximum of 700V single-phase voltage, the power to maintain 2/3 of the original. three-phase mode, the user through the panel of the machine can choose to realize the Y-type and Δ-type connection, Y-type connection to support the C-phase phase missing function. Function. Free and flexible matching to meet diversified testing needs.

Multiple modes of operation

The IT8200 series can turn on the Rectified rectification function in AC mode, so that the load works in the first and third quadrants, and the voltage and current are always in the same direction. At this time, users can select the waveform integrity, including full wave, positive half wave, and negative half wave.

Crest factor CF 1.414-5.0

The crest factor indicates the extreme peaks of the waveform. For applications that require a pure sine wave, it is desired that the CF of the load-side current waveform be 1.414 or as close as possible. However, in practice, the peak shape of the load-side current waveform may become very sharp, and its CF is often greater than 1.414, at which time the starting point of the sine wave is shifted positively by a few degrees from 0 degrees, so the user needs to correct the waveform. Therefore, users need to correct the waveform. IT8200's crest factor (CF) value can be adjusted from 1.414 to 5.0, and also allows users to set the phase shift angle from -90 º ~ 90 º to correct the resultant amplitude, so that the RMS value remains unchanged. This allows more accurate simulation of field test conditions to ensure the reliability of the unit under test (UUT).
