The Italian manufacturer Elettrotest has introduced a new line; the XPS series (eXtreme Power Supply). This line consists of three models with a power range from 18kVA to 67kVA. With extreme performances in the field of stability, accuracy and purity, this Elettrotest is in a class of its own, even with fully capacitive or inductive loads. Variable and pulsing loads are also no problem; the XPS provides a stable voltage within half a period. What makes these high power power supplies so special is their ability to deliver inrush currents that are up to 2 times higher than the nominal current. Even when the requested current exceeds this value, the voltage is temporarily reduced to ensure proper operation.

This makes the XPS very suitable for handling inrush and start-up currents. This makes it an ideal partner for testing all kinds of motors and switching power supplies. Due to its large frequency range of up to 1000 Hz, the XPS is particularly suitable for testing three-phase high-speed induction motors that are frequently used in machine construction. Also electrical systems in the aviation industry with frequencies up to 800Hz can be easily and accurately tested with the XPS.

Another striking new feature is the intuitive graphic touch screen with a clear open menu structure for easy operation. Voltage, phase angle between phases and frequency can be set independently per phase. Data can be stored with a USB stick and for automatic testing a LAN, RS-485 and RS-232 interface is provided.

"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.”
