TTi’s two-channel DC power supplies CPX200D(P)

The two-channel DC power supplies CPX200D(P) are the latest models of the CPX series, with which this series now consists of 7 different models. The CPX power supplies are based on the constant power principle (PowerFlex control). For the CPX200DP this means 2 output channels of 180W each with a maximum voltage of 60V and a maximum current of 10A.


The outputs are fully isolated and can therefore also be put in series (maximum 360W / 120V) or parallel (maximum 360W / 20A).
With a typical ripple and noise of >1mV rms, they are also widely used for precision work. Furthermore, the voltage can be set with a resolution of 1mV and an accuracy of 0.05%+10mV and the current with a resolution of 1mA with an accuracy of 0.3%+5mA.

The P of the CPX200DP model stands for programmable. This unit is equipped with a USB, RS232, GPIB and LXI (LAN) interface. Because of this, external control is no problem at all. Labview drivers are also available of course and optionally there is a rackmount kit for mounting in a 19″ rack.  The CPX power supplies are characterized by their wide range of applications (relatively high voltages and currents) at a very competitive price and performance ratio.

For extensive information about the TTi CPX series, please refer to the CPX datasheet.

"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.”
