High power density The IT8200 series is available from 3U stand-alone to 15 U/27 U/37 U cabinets and other different compact structure design. It can meet different test requirements of users from 5k~165kVA, and the voltage output can reach 350V. The size of 3U/15 kVA model is only 1/12 of a conventional type of AC power supply, saving a lot in space and cost and providing users with a high-power test program that can be directly placed on the experimental table. Master/slave parallel, large capacity free combination The 3U model of IT8200 can be master-slave paralleled to to reach 960kVA output at most. It can improve the output current and power capacity to meet the requirements of higher power testing. IT8200 comes with synchronous On/Off input and output signals, which ensure the synchronization of paralleling and ensures synchronous current sharing of multiple modules. After paralleling, all functions are retained and there' s no loss of accuracy, making the construction of the power system faster, more flexible, and more economical, either it is a stand-alone test or ATE system. 3U 3~15 kVA 03 IT8200 Regenerative AC/DC Electronic Load Your Power Testing Solution IT8200 Regenerative AC/DC Electronic Load High efficient power regeneration After parallel, Power up to 960kVA Single-phase/ Three-phase/ Reverse phase IT8200 Optional interfaces Multiple operating modes Various protection functions 15U 27U 37U 04 www.itechate.com Your Power Testing Solution IT8200 Regenerative AC/DC Electronic Load Single-phase, three-phase, reverse-phase The IT8200 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 voltage can be increased to 700V with the power down to 2/3 of the original. Under the three-phase mode, you can choose a Y-type or a -type connection. The Y-type connection supports the C-phase loss. 1 AC single phase AC 1 DC single phase DC 3 AC three phase AC AC D E LTA WYE reverse phase ¶-type connection Y-type connection AC three phase three phase WYE Y-type phase loss Y-type phase loss 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 value of the load current waveform of 1.414 or as close as possible. However, in practical 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 IT8200 can be adjusted from 1.414 to 5.0, and it also allows to set the phase shift angle from -90 º~90 º, correct 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).

At this time, full wave, positive half wave, or negative half wave can be freely selected. full wave positive half wave negative half wave 06 www.itechate.com Your Power Testing Solution IT8200 Regenerative AC/DC Electronic Load Waveform Oscilloscope function The IT8200 series has built-in digital oscilloscope functions, which can collect time domain signals of voltage and current, phase relationship, and perform 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. Further 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. Data record Thanks to the data record function, the IT8200 series can continuously record data for up to 7 hours at the fastest time interval of 100ms, and provides you with a 'trend' graph to check the curve of the entire test process. Up to 6 curves can be displayed simultaneously. In addition, you can also observe the precise data at a certain moment in the trend graph by sliding on the front panel. This function helps to analyze the abnormality of DUT during long-term testing, inflection point under loading, etc. Test data can be exported by a USB for further analysis. Harmonic analysis Harmonic analysis functions include both voltage and current harmonic measurement. In the harmonic mode, the voltage and current total harmonic distortion (THD) and the phase difference test of the harmonic to the fundamental wave can be realized. In addition, you can make multiple harmonic measurements. The test results are displayed in a list, histogram or vector diagram, easy to check. In the meantime, IT8200 AC electronic load also has built-in IEC 61000-3-2 / 61000-3-12 regulations, which can be recalled directly for pre-compliance testing. 07 IT8200 Regenerative AC/DC Electronic Load Your Power Testing Solution IT8200 Regenerative AC/DC Electronic Load Built-in multiple waveforms IT8200 has built-in sine, triangle, square, trapezoidal and clipped-sine wave. These waveforms can be recalled through the menu and displayed on the screen. Further more, the complex testing requirement can be met by further editing the relevant parameters. Harmonic simulation Harmonic test is one of the important test items for EMC immunity. IT8200 series has built-in 30 THD waveforms for quick recall. Thanks to the high-speed DSP technology, IT8200 series can also customize THD waveform. By setting the amplitude and phase, it can simulate up to 50th order harmonics (fundamental frequency is 50Hz or 60Hz), forming a periodic distortion waveform. Intuitive software interface IT8200 series provides free PC software PV8200 with an intuitive GUI. Meanwhile, it allows remote control, even the ATE models without display screen can be programmed, communicated and monitored. 08 www.itechate.com Your Power Testing Solution IT8200 Regenerative AC/DC Electronic Load LIST/SWEEP/Surge&Sag IT8200 series supports NORMAL,LIST and SWEEP mode. Each mode can work with Surge&Sag function. In LIST mode, you can edit multiple steps and any waveform can be selected for each step. One List file can contain maximum 200 steps. Parameters such as frequency, amplitude, running time, and rising slope of each waveform can be edited. The SWEEP function helps to test the efficiency of the switching power supply in AC mode, grab the voltage and frequency of the maximum power point, and make the setting parameters change step by step. Surge&Sag works in each mode of NORMAL/LIST/SWEEP. Use trigger or cycle to control the drop of surge and sag, set the starting angle of the drop, and support waveform smoothing, symmetrical and asymmetrical waveform operations. Waveforms can be quickly created to reproduce waveform distortions or transient events such as spikes, dropouts or any other anomalies. 09 IT8200 Regenerative AC/DC Electronic Load Your Power Testing Solution IT8200 Regenerative AC/DC Electronic Load AC Input Wiring connection Line voltage Line current Apparent power Frequency Power factor Input voltage Input frequency Input current Input power Current range Resolution Accuracy*3 Range Resolution Accuracy AC mode Range Resolution Accuracy Range Resolution Accuracy*5 R Range L Range C Range Rc Range RL Range IL Range Max peak current R Range L Range C Range RS Range Vcap Range Vdiode RangeL Max peak current IT8215-350-90 AC parameter 3phase 3wire + ground(PE) RMS ( 200 ~ 220 V) ±10% *1 ( 380 ~ 480V ) ±10% RMS < 34A < 17kVA 45 ~ 65Hz typ 0.98 Input VLN 30 ~ 350V VLL 51.96 ~ 606V(3phase)/60 ~ 700V(reverse) 16 ~ 500Hz RMS 90A(1phase)/30A(3phase/reverse) Peak 270A(1phase)/90A(3phase/reverse) Crest Factor *2 5 Per Phase 5kVA Max.
