High-Voltage AC Sources for Grid Simulation and Power Electronics
ITECH IT7800H: High-Voltage AC Source for Grid Simulation and AC Testing
The ITECH IT7800H Series comprises programmable three-phase high-voltage AC sources for defined and reproducible AC test conditions. Its focus is on high output voltages and the realistic simulation of different grid conditions.
For grid simulation and power supply testing, dynamic voltage and frequency profiles as well as grid disturbances can be generated in a controlled manner. Distorted grid waveforms, harmonics, and custom waveforms can also be simulated and analyzed. AC+DC operation additionally allows a defined DC component to be superimposed on the AC output.
The IT7800H Series operates as an AC source and not as a regenerative sink. For test applications requiring active energy feedback, a regenerative four-quadrant grid simulator is therefore the more suitable device class.
Alternative Products
For lower AC voltages, the ITECH IT7800 Series is suitable. For regenerative four-quadrant testing, the ITECH IT7900H Series and the ITECH IT7900 Grid Simulator are available.

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.
