Functions and Advantages 

3U/15kVA high power density

With only 3U size, ITECH IT7800 can reach both 15kVA for power and 350V L-N for voltage. Compared with conventional AC source, it saves a lot of space for users.

Master/Slave parallel

ITECH IT7800 series can provide more power by using the master/slave parallel output function, with 64 units in paralleled, to achieve total output power max. 960kVA. IT7800 comes with synchronous On/Off input and output signals, which ensures the synchronization of paralleling and ensures synchronous current sharing of multiple modules. After paralleling, not only all functions are retained, but there is no loss of accuracy. Make the construction of the power system faster, more flexible, and more economical, whether it is a stand-alone test or ATE system, it can be easily reached.

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.
