Regenerative DC Source/Load System
ITECH IT-M3900B: Source/Sink Operation for Dynamic DC Test Profiles
The ITECH IT-M3900B Series combines a bidirectional DC power supply with a regenerative electronic DC load. With up to 6 kW in 1 U, 12 kW in 2 U, 1,500 V, and 1,020 A, compact DC test systems with high power density can be configured.
The IT-M3900B supplies and loads DUTs with a single instrument. In load operation, according to the manufacturer, up to 95% of the absorbed power is fed back into the grid. Fast current direction switching reduces overshoot during dynamic testing. CV/CC priority, adjustable output impedance, and programmable voltage, current, and power slew rates support changing operating points. Up to 10 million sequence points as well as CC, CV, CW, CR, and combined operating modes enable complex test sequences.
Battery Testing, Scalability and System Integration
Battery tests and simulations can be parameterized using voltage, capacity, internal resistance, and state of charge. Stored test curves support selected requirements according to LV123, LV148, DIN 40839, ISO 16750-2, SAE J1113-11, LV124, and ISO 21848; 10 V models are excluded. Master-slave parallel operation increases the available power. USB, CAN, LAN, and Digital I/O are integrated; GPIB and Analog/RS-232 are optional. OVP, ±OCP, ±OPP, as well as overtemperature, voltage-drop, and anti-islanding protection ensure safe operation.
Alternative Products
If your test system requires a dedicated high-power DC supply, the ITECH IT6600D Series provides high DC power in a compact form factor. If you need to apply regenerative loads to both AC and DC DUTs and feed energy back into the grid, the ITECH IT8200E Series is the suitable AC/DC load.

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.
