The Itech IT-M3400 ultra compact bi-directional DC power supplies come in a very compact housing of ½ 19″ rack width and 1U height, and this with a voltage range of 60V, 150V, 300V and 600V at capacities of 200W, 400W and 800W. Higher power outputs can easily be achieved by connecting 16 units in parallel. And this on 16 different channels that can be controlled separately by means of a single interface connection.
The IT-M3400 is a bi-directional regenerative power supply. This means that it can switch very quickly and automatically between sourcing and sinking. Due to its regenerative character, the power supply achieves a high efficiency of 90%, saving on electricity costs and eliminating the need for additional cooling.
The IT-M3400 ultra compact bi-directional DC power supplies have a comprehensive test and simulation function for battery charging and discharging. During testing, protection limits for current, voltage, capacity and charging time can be set. If these limits are exceeded, the power supply stops its charging cycle. In the simulation mode a battery model can easily be defined by setting voltage, capacity, internal resistance and charging percentage. Battery matrices, charge and discharge curves can be programmed or imported from Matlab using the optional BSS2000 software.
In LIST mode up to 100 steps per sequence can be programmed. The IT-M3400 also features a CC / CV priority function, eliminating current and voltage peaks.
The IT-M3400 series power supplies are OVP, OCP, OPP and OTP secured and can optionally be equipped with various interfaces such as RS232, RS485, CAN, LAN, USB_TMC and VCP. The most common communication protocols are supported, including CANOPEN, SCPI and LXI.
The user-friendly operation and high precision in a compact housing makes this power supply an excellent candidate for automated bi-directional multi-channel power and battery testing. The IT-M3400 is of course also perfect to use as a modular stackable table-top model for development and design verification.

"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.”
