The Itech IT-M3900B series is an interesting addition to Itech’s already extensive range of DC power supplies/DC loads.
The IT-M3900B DC power supply/load is available in ratings of 2kW, 4kW and 6kW in a very compact 1U high enclosure. There is also a 12kW version in a 2U high enclosure. With a combination of voltage ranges of 10V, 32V, 80V, 300V, 500V, 800V and 1500V, current ranges up to 1020A and the powerflex capability of these power supplies we actually cover the entire range of applications within the power models. If we need more power or current this is easily achieved by parallel switching up to a maximum of 16 units. The excellent specifications are not affected by this.
In regenerative bi-directional DC power supply mode the power supply can supply both current and power as well as absorb and feed back to the grid. Switching from supply to load is hereby done automatically, quickly and seamlessly without voltage and current switching peaks. As a bi-directional regenerative DC power supply, the IT-M3900B can operate in CV, CC and CP modes. As a full regenerative load, this is a lot more comprehensive with CV, CC, CP, CR, CC+CV, CR+CC and CC+CV+CP+CR. Of course, this DC power supply/load also has OVP, OCP, OPP and temperature protection.
The built-in test curves for the automotive industry Makes this power supply especially also suitable for testing electric vehicles according to the latest standards such as LV123, LV148, DIN40839, ISO-16750-2, SAEJ1113-11, LV124 and ISO21848. These standards are easily recalled from the power supply’s internal memory which saves a huge amount of time for the user.
The LIST function can also be used to build new standards yourself with a variation of set voltage, current, rise and fall times as a function of time.
The IT-M3900B power/load is ideally suited for testing batteries. Both charge and discharge data can be programmed in such a way that a battery can be fully automatically tested for capacity with, of course, required safety parameters included. The data of the test are stored internally and can later be used for reporting.
Emulation of batteries is also possible. The IT-M3900 can be set quickly and easily by means of parameters terminal voltage at full and empty capacity, internal resistance and total battery capacity. Once these are programmed, the user can quickly switch to different State of Charge (SoC) levels as the test requires. This way, there is no need to go through the actual charge and discharge cycle of a physical battery. During testing of battery powered product designs, this will reduce test time and efficiency considerably.
With the optional BSS2000 software, the most complex battery profiles can be easily programmed, stored and simulated.
Of course, the IT-M3900 power supplies can also be used in automatic test systems.
The unit comes standard with USB, CAN, LAN and Digital I/O interfaces. Optional GPIB and RS232 interfaces are also available.

"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.”
