Itech IT7900P High Performance Regenerative Grid Simulator.
Adopting advanced SiC technology, the Itech IT7900P 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 Itech IT7900P up to 15kVA in 3U single unit, and its power can be extended to 960kVA after master-slave parallel connection. Colorful touch screen with intuitive GUI allows Itech IT7900P to directly define different waveforms. The rich operation modes can meet the test requirement of single-phase, three-phase, reverse-phase and multi-channel. It provides high flexibility for testing and can be widely used in many fields such as PV, ESS and EV.
All in one unit: Itech IT7900P series integrates 3 products, a grid simulator(IT7900), an AC/DC power supply (IT7800) and a regenerative AC/DC load (IT8200).
4-Quadrant output: Itech IT7900P series is not only a full four-quadrant power grid simulator, but also a full four-quadrant AC/DC electronic load. It can operate in all four quadrants. The efficient energy regeneration function makes it good for testing the frequency change of grid-connected PV inverters, voltage transients and anti-islanding protection.
