AC, DC, and AC+DC output mode

Start-stop Angle

In the conventional mode, the start-stop angles of the waveform can be set to facilitate surge current tests.

Output Waveform Options

The three-phase output waveform can be independently set to select a sine wave, a square wave, a triangular wave, a clipped sine wave, 30 sets of built-in waveforms, and 6 sets of user-defined waveforms.

Sequence Mode

It has universally programmable settings for each phase of AC voltage, DC voltage, and frequency. Phase, waveform, and time can be independently set according to single-step settings. Trigger phase and loop count can be set, and parameters of three-phase outputs can be separately configured. Any phase abrupt change/crossing test can be achieved. Rich sequence combinations with a high degree of freedom in parameter settings. By setting different combined sequence parameters, high- and low-voltage crossing tests can be completed. Minimum programming setting time is 1ms, capable of completing a 1ms stop test. Each sequence in each phase can independently set one of the 6 waveforms.

Pulse Mode

It periodically changes the output state, where the power output will cyclically vary between a regular power supply and a pulse voltage. Each phase of AC voltage, DC voltage, frequency, angle, waveform, time, etc., can be independently set.

Step Mode

Also known as staircase mode, where the output voltage gradually increases or decreases according to the set step size from the initial value. Each phase's AC voltage, DC voltage, and frequency can be independently set for the initial value and change amount. Angle, waveform, step count, and step time for each phase can also be set independently.

Harmonic Synthesis

The power supply has a harmonic editing function (2-50 times), and various harmonic components can be added to the standard sine wave. It has 3 sets of percentage harmonic storage groups and 3 sets of amplitude harmonic storage groups that can be quickly called. The fundamental wave voltage, harmonic content, angle, etc., of each phase can be independently set. Under the percentage mode, the content and angle of each harmonic can be set, with a single harmonic up to 30%, no limit on total harmonic content, and no limit on the number of harmonic superimpositions. Under the amplitude mode, specific voltage values can be set for harmonic components without any percentage relationship with the fundamental wave voltage.

Interharmonic Synthesis

The power supply has an interharmonic editing function, allowing the addition of interharmonic components to the standard sine wave. Interharmonic trigger angle, start-stop frequencies, content, and scan time can be set, with an interharmonic frequency range of 16-3,000Hz.

Operation

A 5-inch color capacitive touch screen and knobs can be used to set the voltage and frequency in the conventional mode, with buttons responsible for starting and stopping the conventional mode.

Upper Computer

It is equipped with the standard upper computer software, with a graphical user interface for convenient and efficient operation.
