Elettrotest S.p.A. was founded in 1986 to develop and manufacture professional electronic products after various end user needs. The first products were made to the purpose of online registration, and for testing and characterizing asynchronous engines. Manufacturing gradually expanded to include various civil and industrial applications control, especially those with thermostatic control for air conditioning and heating.

In accordance with the trend of development test and measurement equipment development, a line of AC power supplies with stabilized and programmable frequencies and voltages was designed. The current product range comprises a complete line of 23 AC power supplies, ranging from 1500VA single phase to three-phase 200kVA units.

– AC single phase power supplies
– AC three-phase power supplies

The big advantage of Elettrotest AC power supplies, is that they are designed to supply inrush current. All units can deliver twice as much than the rated current during three seconds. This is ideal to start engines or provide inrush current to switched DC power supplies.

"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.”
