Regenerative Grid Simulator for Grid Simulation, AC/DC Testing and PHiL
ITECH IT7900EP: Simulate Grid Events and AC/DC Conditions in a Controlled Manner
The ITECH IT7900EP Series is a regenerative grid simulator for PCS, energy storage systems, microgrids, and grid-connected power electronics. In four-quadrant AC/DC operation, it supplies power, absorbs energy from the DUT, and feeds it back into the grid.
Flexible Grid Simulation for AC, DC and Mixed Signals
Harmonic and interharmonic synthesis, anti-islanding, and Low Voltage Ride Through simulate defined grid events. The AC, DC, AC+DC, and DC+AC output modes cover conventional grid simulation as well as testing with DC or combined AC/DC signals. This makes it possible to evaluate how systems respond to changing supply and grid conditions.
Scalable Power into the Megawatt Range
The series covers 21 to 126 kVA and can be expanded to 1 MVA and above using master-slave operation. Up to 350 V AC L-N or 606 V AC L-L support low-voltage grids and industrial test applications. In sink operation, energy is fed back into the grid instead of being dissipated as heat. In Power Hardware in the Loop (PHiL) applications, the IT7900EP operates as a power amplifier between the simulation environment and the physical DUT.
Alternative Products
For power levels below 21 kVA, the ITECH IT7900P is suitable; for applications without additional load functionality, the ITECH IT7900 is an alternative.

Supplier
LXinstruments has been supplying ITECH equipment since 2020. When an individual instrument needs to become part of a complete test system, we support you with product selection, system sizing and integration into the automation environment. The key is to ensure that the DUT, power requirements, interfaces and test sequence work together.
We also use ITECH equipment in customized test systems. Depending on the test application, we combine power supplies, electronic loads, grid simulation and measurement technology so that the functions match both the DUT and the test sequence.
