The Magna-Power MagnaLOAD WRx series DC loads 15 kW – 120 kW+ are available in 15 models. These models are based on the by Magna-Power Electronics patented Active Resistance Technology. This is a binary switched resistor network in combination with linear technology based on conventional MOSFETs. The WRx series is water-cooled!
The Magna Power WRx series has a 16-bit resolution for programming and measuring functions of these DC loads. It is suitable for voltages from 200Vdc to 1000Vdc and currents from 30Adc to 2400Adc. Besides the standard CV, CC and CR modes, the applied Active Resistance Technology in the MagnaLOAD WRx series offers the so-called Rheostat (control resistor) control mode.
Besides an impressive line of DC power supplies Magna-Power also carries the MagnaLOAD product line with programmable DC loads. The ALx Series, ARx Series, and WRx series consist of 39 water and air cooled models from 1.25 kW to 120 kW+. They are suitable for voltages of 0-1.000Vdc and 0-1.200Adc. All MagnaLOAD models feature the MagnaLINK™ DSP controller, hence contributing to impressive functionality. The Magna-Power DC loads are standard equipped with a 25-pin D-Sub connector for external I/O. This connector has 8 Digital Outputs, 4 Digital Inputs, 4 Analog Outputs, 4 Analog Inputs and is user configurable.
The MagnaLOAD WRx series models are:

"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.”
