Functions and Advantages

7” DSO function

Display real-time waveforms of voltage and current under the stand-alone or parallel mode

IT7600 series high-power AC / DC power supply provide a powerful oscilloscope function by the 7” large screen. Built-in high-speed sampling measurement design realizes the display of real-time voltage and current curves. When multi-units are paralleled, IT7600 can display the status of all paralleled units, instantaneous  analysis is available without an oscilloscope.

Output frequency up to10-5000 Hz

Output variable rate of voltage or frequency is adjustable

IT7600 series high-power AC / DC power supply output frequency is adjustable during 10-5000 Hz. IT7600 series have a wide range of applications, which meets the low-frequency demand for general commercial industry.

IT7600 series allows users to set their own output fluctuation rate of voltage or frequency, so that the voltage or frequency regularly reach the set value step by step. It is more accurate to verify the product operation scope and also can reduce surge current of DUT when starting up. 

Achieve AC, DC, AC+DC output modes

AC+DC can achieve offset simulation of DC Voltage

IT7600 series high-power AC / DC power supply can achieve AC, DC, AC + DC output modes, not only provide pure AC / DC output, but also can provide AC + DC output mode to expand application and test DC bias components.

Strong master-slave paralleling function

Using power in more flexible way

The IT7600 AC / DC power supply models provide the strong (Master-Slave) parallel operation function, which enable users to extend the current / power output ability to save cost. During parallel connection operation, it only requires the setting on Master unit, and the slave unit will be controlled by the master unit automatically. This function greatly simplifies the paralleling operation. IT7600 series have built-in synchronous On / Off input and output signals, which ensures the synchronization and equalized current output on multi modules synchronously.

IT7600 after paralleling of 3 sets, each unit will share the test current averagely 

Support single / three-phase output

Simulate unbalanced three phase output
IT7600 series high performance programmable AC / DC power supply supports single / three-phase output and can achieve test applications for three-phase AC power supply. Users can achieve Y-type and Δ-type connections according to actual requirements.

♦ IT7627 / IT7628 Support one key to switch single / three-phase output through the panel or software, easy to operate.
♦ IT7622 / IT7624 / IT7626 can also achieve three-phase AC power test applications through multiple paralleling.
♦ IT7628L / IT7630 / IT7632 / IT7634 / IT7636 support three-phase output. When IT7600 series realize three-phase output, IT7600 can simulate unbalanced three-phase output, expanding the scope of application.

When IT7600 series realize three-phase output, IT7600 can simulate unbalanced three-phase output, expanding the scope of application.

Built-in abundant waveform database

Recall by menu and display the selected waveform on the LCD screen

IT7600 series high power AC / DC power supply provide built-in a variety of different types of waveforms, such as triangle wave, sine wave, surge at peak, trap wave, and other waveforms, the user can recall by menu and display the selected waveform on the LCD screen.

List mode

List mode can simulate civil use AC network, achieve simulation of instantaneous power interruption

IT7600 series high-power AC / DC power supply provide users a simple way to achieve the output parameters changing gradually or continuously through STEP mode and LIST mode. The amplitude of output voltage, frequency, phase, waveform and other parameters can also be output by controlling the internal trigger or external trigger of the instrument. Thus you can simulate a variety of power instantaneous power interruption, surge, ramp and other characteristics.

Support CSV file to import waveforms

Import a CSV file via the USB interface to generate a waveforms output

The user can edit the waveform output by the panel LIST function or can import a CSV file via the USB interface to generate waveform output. At the same time, IT7600 series provides external ± 10 V analog interface, users can choose separate AM and FM amplitude modulation to receive external signal source.

Strong harmonic analysis function

Voltage / current harmonic measurement

IT7600 high-power AC power supply is with powerful function in harmonic analysis, including harmonic measurements for voltage and current. For harmonic
measurements, when frequency is 10-500 Hz, IT7600 can test 50th; when it’s above 500 Hz, then 20th. In harmonic mode, it can do tests for U / I THD (Voltage / Current Total Harmonic Distortion) factors, as well as Phase tests. Besides, IT7600 can do multiple harmonic measurements, the results are displayed in list or histogram, so that the test results are more clear.

Strong harmonic simulation capability
