IT8200E series regenerative AC/DC electronic load can efficiently feed power back to the grid. In a 3U rack, it can input up to 21kVA at most. Through master-slave paralleling connection, its power can be easily expanded to more than 1MVA.Its touch screen and GUI allow the editing of various waveforms. Combined with arbitrary waveform editing functions and full protection, IT8200E is a good choice for R&D, testing and system integration.In AC mode, you can turn on the 'Rectified' function to make the IT8200E electronic load work in the first and third quadrant, with the voltage and current maintaining the same direction. It also provides a variety of working modes, such as CE mode, which can simulate 14 circuit topologies. IT8200E series can be used for a wide range of applications, including V2G, EVSE, Inverter, PCS, UPS, etc.

Functions and Advantages
Regenerative AC/DC electronic load
The IT8200 series are new regenerative AC Electronic Load with 88% energy recovery capability. Whether in AC mode or DC mode, the power generated by the DUT can be fed back to the grid, rather than being dissipated as heat, which protects the environment and save the cost of electricity, HVAC and cooling infrastructure.
Single-phase, three-phase, reverse-phase
The IT8200E series are new regenerative AC Electronic Load with 88% energy recovery capability. Whether in AC mode or DC mode, the power generated by the DUT can be fed back to the grid,rather than being dissipated as heat, which protects the environment and save the cost of electricity, HVAC and cooling infrastructure.
Oscilloscope function
The IT8200E series has built-in digital oscilloscope functions, which can collect time domain signals of voltage and current, phase relationship, and per form waveform triggering, etc. Its sampling rate is as high as 10us, up to 6 oscilloscope curves can be displayed at the same time, and instantaneous analysis can be completed.Fur ther more, with its data recording function, you can observe the output for a long time, and store the obtained data to an external storage device for secondary analysis. A wide variety of test requirement can be met even without a data acquisition instrument or an oscilloscope.
Oscilloscope function
The IT8200E series has single-phase, three-phase, and reverse-phase output modes, which can be selected through the menu. Under reverse mode, the single-phase 350V input v oltage can be increased to 700V with the power down t o 2/3 of the original. Under the three-phase mode, you can choose a Y-type or a Δ-type connection. The Y-type connection supports the C-phase loss.
Various Operating Mode
IT8200E AC electronic load can enable the 'Rectified' function in AC mode, so that the load works in the first and third quadrants to ensure that the voltage and current flow always in the same direction. At this time, full wave, positive half wave, or negative half wave can be freely selected.
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 desirable to have a CF v alue of the load curr ent waveform of 1.414 or as close as possible. However, in pr actical applications, the peak shape of the current waveform of the load may become very sharp and its CF is often higher than 1.414. At this time, the starting point of the sine wave starts to shift from 0 degrees to the positive degree. So you need to correct the waveform. The Crest Factor of the IT8200E can be adjusted fr om 1.414 t o 5.0, and it als o allows to set the phas e shift angle fr om -90 º~90 º, corr ect the resulting amplitude, and keep the RMS unchanged. This enables more accurate simulation of field test conditions to ensure the reliability of the unit under test (UUT).
