Home » NGL200 Bi-directional Lab Power supplies from R&S
The NGL200 bi-directional Lab power supplies from Rohde&Schwarz are again an addition to the broad line of laboratory DC power supplies.
The high resolution and accuracy of the NGL200 power supplies makes them perfect for challenging applications. The 2 quadrant (unipolar) power supply with a linear output stage makes it possible to both supply power (source mode) and dissipate power. (Sink mode) and is therefore excellent for emulating batteries. This with an extremely low noise and ripple specification.
The series consists of two models; the NGL201 and the NGL202 with respectively one and two fully galvanic isolated channels.
Each channel has a maximum output power of 60W. This at an adjustable voltage between 0 and 20V. At voltages below 6V, the maximum current is 6A. Above that, the maximum current is 3A. Of course the power supply is equipped with sense lines so you can be sure that the accurate voltage is actually at the terminals of the DUT.
Unique to this DC power supply is the super fast load response. This is smaller than 30µsec which is really fast for a DC power supply. You can choose from three operating modes, Constant Current, Constant Voltage and Constant Resistance. To protect the test unit it is possible to set safety limits. And also this with an extremely high resolution.
The operation of the unit is extremely intuitive by means of the beautiful large touch screen. The reading of the actual test values is done with a 6½ digit digital multimeter. The NG200 power supplies can be programmed via USB or LAN interface. Optional are the Wireless LAN and GPIB interface.
The NLG200 series is extremely suitable as a precision DC power supply for testing semiconductors in line with applications for IoT’s and battery cell emulation. An adjustable output impedance ensures accurate emulation at different currents.

"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.”
