The Itech IT-M3400 ultra compact bi-directional DC power supplies excel with their versatility, ease of operation and high accuracy. And this in an extremely compact housing of ½ wide 19″ rack module of 1U high. The power supplies are available in four different voltage ranges (0-60V, 150V, 300V and 600V) at power ratings of 200W, 400W and 800W.


The most important feature of the Itech IT-M3400 Ultra Compact Bi-directional DC power supplies is the integration of the functionality of a bi-directional power supply and a regenerative electronic load. The unit automatically switches between power supply and load at lightning speed according to the circumstances, without overshooting current and voltage. Its regenerative character also makes the IT-3400 an enormously efficient power supply. The absorbed DC power is converted to AC and fed back into the grid with an efficiency of 90%. As a result, considerable savings can be made on air conditioning and electricity costs.


With the standard software it is possible to easily charge and discharge the battery. With the extensive ITS5300 software you can also perform extensive drive cycle testing, life cycle testing, IR testing etc. In cooperation with the extensive BSS2000 battery simulation software, the IT-M3400 power supply is ideal for simulating battery modules. Specific properties of the battery can be programmed and thus the electronics around the battery can be tested. The specific battery conditions are then very easy to simulate.


Thanks to the ability to connect different IT-M3400 power supplies in parallel, a wide power range can be covered. Also, up to 16 channels can be controlled independently or synchronously with a single interface. The compact design makes the IT-M3400 an excellent candidate for installation in automatic test systems to perform multi channel tests.

Ideal for large-scale testing of power electronics such as IGBT Power Modules or bi-directional DC/DC converters commonly used in electric vehicles.

The IT-M3400 series is of course available with common I/O interfaces and compatible with most communication protocols.

For detailed specifications please refer to the datasheet of the IT-M3400.

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
