With the introduction of the NGM200, Rohde & Schwarz has developed a bi-directional, programmable power supply, especially meant for engineers involved in the development of battery powered equipment. The NGM200 power supply is available in a 1 and 2 channel version, suitable for voltages up to 20V and currents up to 6A.

For each battery powered device, simulating changes in the performance of the battery output provides realistic conditions at different stages of the battery life. With the integrated battery model editor in the NGM200 power supply, users can create their own battery models by defining battery characteristics such as charge status, open-circuit voltage and series resistance. Pre-defined data sets for common battery types Lead, Lithium-Ion, Nickel-Cadmium or Nickel-Metal hydride are included.

Furthermore, the NGM200 power supply is further characterized by the addition of new features including a built-in digital multimeter, a Fastlog function up to the µs range, the battery simulation option, and an improved read-back function up to a resolution of 10 nA / 5 µV in the low ranges.

The R&S NGM200 is family of the comparable R&S NGL200 and, thanks to its high accuracy, can be used for challenging applications. The 2 quadrant, linear output stage makes it possible to supply power (source mode) as well as dissipate (Sink mode). Partly due to the excellent noise and ripple specifications, the NGM200 is a welcome addition to any R&D lab.

"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.”
