Power test solutions provider Itech has released a distinctive line of programmable, high power, AC/DC power supplies with the IT7800 series. The Itech IT7800 programmable AC/DC power supplies deliver up to 15 kVA in a housing only 3U high. This at a voltage range of 0-350V L-N. The intuitive touch screen ensures smooth operation. The Itech IT7800 also has a built-in power meter and waveform generator with which harmonic distortion can be programmed in addition to various waveforms. By connecting units in a Master-Slave parallel set-up this makes configurations possible up to 960kVA.

A special feature of the Itech IT7800 is that it has 4 output modes. Besides the AC, DC and AC + DC modes, the DC+AC mode is also available. Thus, an AC grid + DC offset and a DC grid + AC ripple can be generated. This is possible for both 1- and 3-phase applications. With the striking new “reverse phase” function, the standard 350Vac is doubled to 700Vac.

The STEP, LIST and PULSE modes make the Itech IT7800 series suitable for simulating changing AC and DC grids. This includes for example short term PQ events. The analysis and simulation up to the 50th harmonic and the programmable output impedance makes the Itech IT7800 suitable for many applications including standard IEC tests. Remote control is possible via the standard USB/CAN/LAN and digital I/O interfaces.

"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.”
