The IT-M3900D is a new line of accurate and compact programmable DC power supplies from Itech. Available in power ratings from 2kW to 12kW, these power supplies position themselves nicely in that area between the already existing IT-M3100 series for smaller power ratings and the IT6000D series for large power ratings. There is a choice of 25 versions covering voltage ranges from 0 to 10V, 32V, 80V, 300V, 500V, 800V and 1500V and current ranges run up to a maximum of 1020A. All this with an efficiency of up to 95%; this keeps the losses in converting the AC mains voltage to the requested DC voltage to a minimum even at full power.
Typical of the IT-M3900D is its ultra-compact enclosure of only 1U and 2U rack height for capacities up to 6kW and 12kW, respectively. Partly due to its modular design, this makes the power supply ideal for space-saving installation in ATE systems. But also on a test bench, these power supplies can be easily and safely stacked without compromising heat dissipation. Up to at least 8 units can easily be connected in parallel for higher outputs. This can be done very easily by looping multiple IT-M3900s through with an optical cable and putting the setup in Master/Slave mode. Excellent performance and stability remain guaranteed.
Like most ITECH DC power supplies, this IT-M3900D series is equipped with auto ranging powerflex functionality. The maximum power of this power supply can be used over a wider voltage and current range than conventional DC power supplies. As an example, the 80V 12kW IT3912-80-240 power supply: at 80V up to 150A can be supplied, but at voltages from 50V and below, 240A is the maximum current.
The Itech IT-M3900D features an innovative CC/CV priority setting to maximize its test compatibility. Under CV priority mode, the power supply can obtain faster voltage rise times to reproduce transients, among others. Switching to CC priority mode is going to ensure that there is no overshoot due to peak current during switching. This in turn is suitable for performing tests on semiconductors that can be sensitive to current spikes.
Furthermore, the Itech IT-M3900D excels with its user-friendly user interface. It can be operated manually as well as with a PC and the free control software. With this, measurements can be easily performed and stored. DC voltage and current sequences up to 200 steps with variable rise and fall times can be programmed, executed and stored with the built-in LIST function. Self programming can be done with the most common communication protocols CANOPEN, SCPI and LXI. The IT-M3900D is equipped as standard with the usual USB, CAN, LAN and Digital I/O interfaces for this purpose, optionally GPIB and RS232 also remain among the possibilities. To ensure safe operation, the power supplies are OVP, OCP, OPP and temperature protected.
Both in production environments and research departments, the IT-M3900D series can be an interesting asset. For bi-directional applications, please refer to the IT-M3900B and the IT-M3900C.

"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.”
