The Elettrotest TPS series of single-phase AC power supplies has recently been extended with four new models in the power range from 1500VA to 9000VA. The TPS-D units have a completely redesigned user interface compared to the older models. The unit has a nice 7″ colour touchscreen display combined with a rotary knob to easily make all settings and read the actual measured values.

There are two voltage ranges: 0-150V and 0-300V and the frequency range is from 10 to 80Hz. These AC power supplies have an RS-232, RS485 and LAN interface as standard. A Labview driver is also available if you also want to use this AC power supply in an automated environment. The power supplies are protected against short-circuit, overload and excessive temperature.

All Elettrotest TPS AC power supplies in the single-phase series have an inrush current capability of 2x the rated current. And that for three seconds. This is interesting, for example, considering the inrush current of switched-mode power supplies, motors and compressors.

For detailed specifications, please refer to the TPS/M/D datasheets.

"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.”
