Bidirectional DC Power Supply for Battery, DC/DC Converter, and Automotive Testing
ITECH IT-M3400: When the DUT Absorbs and Returns Energy
In battery, DC/DC converter, and automotive testing, power often flows in both directions. The ITECH IT-M3400 Series is designed for exactly this task: it operates as a DC source and then absorbs energy again as a regenerative sink. In standalone operation, it switches quickly and seamlessly between source and sink. This enables charge and discharge cycles as well as bidirectional DC/DC testing with a single instrument.
Choosing the right model primarily depends on the DUT voltage and power requirements. The twelve models cover 60, 150, 300, or 600 V and power ratings of 200, 400, or 800 W; depending on the voltage range, currents of up to ±30 A are available. In sink operation, the IT-M3400 feeds up to 90% of the absorbed power back into the grid. This reduces heat dissipation in the test system, especially during repetitive charge and discharge cycles.
Different battery states can also be simulated without relying solely on actual charge cycles. With the optional BSS2000 software, voltage, capacity, internal resistance, and SOC can be defined, while actual charge and discharge curves can be imported from CSV files. For parallel test applications, the series can be expanded to systems with up to 256 independently configurable and synchronously controlled channels.
Alternative Products
If 800 W is not sufficient, the ITECH IT-M3900B Series extends the same concept into higher power ranges. For test systems with significantly higher DC power requirements, the ITECH IT6000C Series is a suitable choice.

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.
