Functions and Advantages

Application

3U/21kVA high power density

With only 3U size, ITECH IT7800E can reach both 21kVA forpower and 350V L-N for voltage. Compared with conven tionalAC 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.

AC、DC、AC+DC、DC+AC

The IT7800E series has four output modes: AC, DC, AC+DC, DC+AC. It not only provides pure AC/DC output, but also can use AC+DCand 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 IT7800E 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, IT7800E'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.
