The IT7800 series is a highly flexible AC/DC power supply designed to meet the testing demands of new energy, power electronics, and scientific research sectors. The system's advanced capabilities in harmonic simulation, arbitrary waveform generation, and multi-channel testing ensure that it can handle the most complex power simulation tasks.

The unit’s SiC technology not only improves energy efficiency but also reduces system size, achieving 15kVA in a 3U unit, while ensuring high performance and low heat generation. The multi-channel testing feature enables users to test up to 3 DUTs (devices under test) simultaneously, eliminating the need for additional AC supplies and improving cost-effectiveness.

Whether for AC power testing, DC supply, or combined AC+DC applications, the IT7800 covers a wide range of testing applications, including low voltage ride-through (LVRT), surge, and sag simulations. It can be easily integrated into automated test systems (ATE), thanks to its intuitive touch screen interface and standard communication interfaces (USB, CAN, LAN, optional GPIB/RS232).
