Home » Itech IT-M3900B compact regenerative DC power system
Itech is introducing a new innovative and advanced technology to the market with the IT-M3900B Regenerative DC Power System. This IT-M3900 combines a bi-directional power supply and a fully independently controllable regenerative electronic load in one housing. At the touch of a button, it is easy to switch between the two functions.
In load functionality, the regenerative nature of the IT-M3900B ensures that the absorbed energy is fed back to the local grid with a high efficiency of up to 95%. This eco-friendly design minimises heat generation and helps to significantly reduce electricity costs. This makes the IT-M3900B another pioneering high-tech product and an excellent addition to Itech’s already existing bi-directional range.
The IT-M3900B regenerative power system has a flexible and modular design. The result is an ultra-compact enclosure for powers from 2 to 6kW, 1U high and 12kW, 2U high. To cover the widest possible area of applications, there is a choice of 25 models with a voltage range from 10V to as much as 1500V and current ranges up to 1020A
The IT-M3900B series is modularly designed so that multiple units can be stacked or built into a rack. The user has the option of designing such a multi-channel power supply with synchronised outputs or by master/slave parallel switching to increase the power.
This Itech power/load combination is equipped with a lot of functionality such as a battery emulator and a battery cycle tester, among others. The IT-M3900B power system also features pre-programmed compliance tests of most common automotive standards. Among others, for testing components such as bi-directional On Board Chargers (B-OBC) and bi-directional DC/DC converters found on the latest electric cars today.
The IT-M3900B series comes standard with a LAN, CAN and USB interface. A GPIB interface and the combination RS232 / analogue interface are optional.
For detailed specifications, please refer to the IT-M3900B datasheet.

"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.”
