The IT7900EP High Performance Regenerative Grid Simulator is designed for high-power applications in fields such as solar energy, energy storage systems, and electric vehicle (EV) testing. It provides an all-in-one solution, functioning as a regenerative grid simulator, AC/DC power supply, and electronic load.

With high power density and the ability to regenerate energy, the IT7900EP is highly efficient, enabling power to be returned to the grid, which helps to reduce both energy and cooling costs. This makes it an environmentally friendly option for testing grid-connected devices such as photovoltaic inverters, energy storage systems, and microgrids.

The unit offers flexible output modes and supports harmonic simulation and voltage regulation for low voltage ride-through (LVRT) conditions, making it ideal for compliance testing with standards such as IEC61000-4-11, IEC61000-4-13, and IEC61000-4-28. It also supports the simulation of voltage transients, phase jumps, and other power disturbances.

The intuitive touch screen interface and advanced waveform editing capabilities allow users to easily configure and monitor the system, while the built-in oscilloscope provides real-time analysis of voltage, current, and phase. The IT7900EP series is designed to meet the rigorous demands of R&D, production, and regulatory testing in the power electronics industry.
