Itech’s recently released IT-M3140 series can be used in practically any situation where a stable DC source is required. ITECH has chosen to cover a very wide voltage range with this series. Available in as many as 7 ranges from 30V to 1200V in both 1850W and 3000W versions in a compact housing. With its PowerFlex flexible control range, the IT-M3140 is even more universally usable than power supplies with a classic fixed control range. In addition, the power supply is fully programmable and DC sequences can be built to simulate, among other things, the behaviour of a distorted DC source.

Precision and stability

The IT-M3140 has everything the demanding engineer expects from a programmable DC source. High stability of the requested DC voltage under varying load profiles or mains voltage fluctuations. Many safety functions that not only protect the power supply from overloading, but also protect the Device Under Test from damage. For this purpose, the IT-M3140 is also equipped with a priority mode to eliminate short current spikes. During switching between different voltage levels while testing sensitive electronics, this is essential.


Due to its flexible and accurate character, the IT-M3140 series can be used in many applications.
Think of a design department for communication modules frequently used in the automotive sector. These modules are powered with a DC voltage and it is necessary to test within which DC limits the modules remain operational. The IT-M3140 also offers a solution when certifying and performing endurance tests on DC-DC converters for electric cars. These tests can be automated by integrating the power supply into an automatic test system (ATE). For this purpose, the IT-M3140 is equipped with the most common communication ports. Control software for controlling and programming is available free of charge.

With the IT-M3140 series, ITECH continues to innovate and expand their range of high-quality test equipment for the demanding technician.

For detailed specifications, please refer to the datasheet of the IT-M3140.

"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.”
