IT7900EP High Performance Regenerative Grid Simulator

Adopting advanced SiC technology, the IT7900EP series high-performance Regenerative grid simulator provides an all-in-one test solution that can be used not only as a grid simulator and four-quadrant power amplifier, but also as a four-quadrant regenerative AC/DC electronic load.The full four-quadrant operation, regenerative ability can feedback power to the grid, meet the needs of environmental protection, but also save a lot of electricity and heat dissipation costs. Compact, modular and efficient structure design allows the IT7900EP up to 21kVA in 3U single unit, and its power can be extended to 10MVA after master-slave parallel connection. Colorful touch screen with intuitive GUI allows IT7900EP to directly define different waveforms. The rich operation modes can meet the test requirement of single-phase, three-phase, reverse-phase. It provides high flexibility for testing and can be widely used in many fields such as PV, ESS and EV.
