Vitrek introduces the new PA920 series of power meters, setting a new standard in measuring accuracy in electrical power measurement. This power analyzer is equipped with broadband waveform digitizers with advanced computing power for an extremely competitive price.

The PA920 consists of a mainframe with 4-slots for different power analyzer channels. The possibilities in terms of channels vary in accuracy, bandwidth and internal powershunt ranges. Each channel has its own digitizer and FPGA for all calculations. All results of the different channels are brought together in the mainframe for further calculations and display on the large touchscreen color display. In addition to the measuring channels, a map is also available for measuring the mechanical energy of a motor in the form of torque and speed.

High accuracy Vitrek PA920

The Ultra high precision Twin shunt (UT) channels achieve a basic accuracy of 0.024% for power measurements, making this unit the most accurate power analyzer in its price range. Within the PA-900 series from Vitrek you have a choice of 20 different channel configurations. Do you need more than four channels? This is easy to realize by connecting multiple mainframes. This up to a maximum of 400 channels.

Easy to operate

The high resolution display makes the Vitrek PA920 extremely easy to operate. The measurement results can easily be made visible in the form of a numerical display or by means of a waveform display. You can also perform efficiency calculations and, for example, harmonic calculations. By means of a freely programmable “custom display” you can even program the display of your measurements according to your own wishes. This way, the display can be perfectly personalized for each specific application.

The unit also has an extensive range of integrated standardization tests. These include Standby power measurements, the EN60034-2-1:2014 standard for measuring engine drives and avionics measurements such as the Airbus ABD0100 and Boeing 787B3-0147. All in all a very versatile power analyzer suitable for the most demanding applications.

For detailed specifications please refer to the datasheet of the Vitrek PA920/910.

"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.”
