Product information "Regenerative grid simulator | IT7900 Series"
ITECH IT7900 Series
Programmable, regenerative 4-Quadrant AC Grid Simulator
Power: up to 165 kVA, Voltage: 350 V, Current: up to 990 A
The IT7900 series represents the latest generation of programmable four-quadrant grid simulators and can also be used to test various grid-connected equipments. The advanced SiC semiconductor technology provides high power density in a small footprint. The series offers 6 kVA in a 1U size. When connected in parallel in master/slave mode, the power can be extended up to 960 kVA. Various operating modes meet different test requirements from single-phase, three-phase, antiphase and multi-channel. In addition to supplying sensitive applications with precise alternating current, the IT7900 series is able to simulate distorted voltage waveforms, interference signals and grid faults.
