Multi-channel function

The multi-channel function of the IT7800 series allows users to test 3 independent DUT at the same time without adding additional hardware configuration. In the traditional solution, 3 tests for the DUT, the user needs to configure 3 AC power supplies; and one IT7800 device can meet multi-channel testing requirements. For example, IT7815-350-90 rated power is 15kVA, can provide single-phase/three-phase 15kVA DUT test, can also meet up to 3* single-phase DUT test, one machine with multiple functions, fully improves the equipment utilization.

​
AC、DC、AC+DC、DC+AC

The IT7800 series has four output modes: AC, DC, AC+DC, DC+AC. It not only provides pure AC/DC output, but also can use AC+DC and DC+AC output modes to realize "AC output plus DC bias" And "DC output waveform with ripple", which cover a wider range of applications.




Single phase, three phase, reverse phase

The IT7800 series provides multiple output modes such as single-phase, three-phase and reverse phase, which can be selected by the user through the panel menu. By programming ,it can simulate three-phase unbalance, three-phase harmonic unbalance, lack of phase test, phase sequence reverse connection and other tests, which are flexible and cover more applications. At the same time, IT7800's reverse mode can also provide a high-voltage test solution. Its voltage can be increased to twice and the power remains 2/3.
For example, if it is set to 350V, the actual output voltage can reach 700V after the reverse mode is selected.
