TT&MS supplied a customer specific 20kVA AC power supply from Elettrotest for Moba. This is used to generate a stable but adjustable 50Hz and 60Hz AC grid. The applied AC power supply is suitable for an output voltage of 0-150Vrms and 0-300Vrms L-N, and can be used in single and three-phase applications.

This special version is equipped with various three-phase connections and is used by the end user for the necessary tests during production and when assembling the complete system. For this purpose different AC grid conditions have to be simulated. This is in order to guarantee a good and reliable functioning of the end products, worldwide.

For practical reasons, the AC power supply is placed in a specially developed steel frame. This makes it suitable for transport by forklift truck. As a result, transport within the various production locations is guaranteed fast and safe.

AC power supplies are used in applications where a stable and clean (low THD) mains voltage is required. In many applications it is desirable to be able to vary both the output voltage and mains frequency. Besides generating a clean mains voltage, AC sources are also used to consciously generate harmonic distortion or other power quality related events.

This specific solution was part of the RTLZ programme ‘How it’s done’, click here for the item.

WHAT OUR CUSTOMERS SAY

Arnold Memelink

ABB

"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."

Sasan Rafii-Tabrizi

University of Luxembourg

“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.”
