Regenerative Electronic AC/DC Load for Precise Load Simulation

ITECH IT8200: AC/DC Load for Reproducible Testing

The ITECH IT8200 Series is a programmable electronic AC/DC load for laboratories, development, and industrial test systems. It reproduces defined load profiles in DC and AC operation and precisely controls voltage, current, and load behavior.
With 15 kVA in 3U and 6 kVA in 1U/2U, it combines high power density with compact system integration. Accessories, compatible AC and DC sources, and system connectivity support automated test setups and reproducible AC/DC testing.

AC/DC Circuit Models and Regenerative Energy Feedback

The IT8200 simulates different load and circuit models, including single-phase rectifier RLC and parallel RLC circuits. This allows power sources, DC power supplies, and other AC/DC systems to be tested under defined load conditions and their behavior at changing operating points to be analyzed.
In regenerative operation, the electronic load feeds absorbed energy back into the utility grid during both AC and DC testing. This reduces energy consumption, heat generation, and cooling requirements and supports efficient testing of components and systems. In combination with existing power sources and DC power supplies, the load can be integrated into existing test environments.

Alternative Products

If you are looking for an AC/DC load without regenerative operation, the ITECH IT8600 Series, offering up to 14.4 kVA and an integrated oscilloscope, is a suitable alternative. For regenerative AC/DC load testing at higher power levels, the ITECH IT8200E Series is a higher-power alternative within the same product class.

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.
