ITECH IT7900E Series – Regenerative Grid Simulator
The IT7900E series is a programmable, four-quadrant grid simulator and power amplifier designed to test various grid-connected equipment, such as PCS, energy storage systems, microgrids, V2X (Vehicle-to-Everything), PHiL, and more. Utilizing advanced SiC technology, a single unit of the IT7900E can perform anti-islanding protection tests through its islanding mode with adjustable RLC settings. The series boasts high power density, delivering 6kVA in a 1U unit and 15kVA in a 3U unit. Through parallel connection, its power capacity can be expanded up to 960kVA.
The IT7900E series offers a variety of operating modes to meet diverse testing requirements, including single-phase, three-phase, reverse-phase, and multi-channel configurations. In reverse mode, the voltage can be extended to 200% of the rated voltage. Its robust arbitrary waveform editing function allows for the simulation of various power grid disturbance waveforms, making it an ideal choice for testing and R&D laboratories.
