H&H, manufacturer of an impressive line of electronic loads and four quadrant power supplies, has developed the new SCL series especially for testing high-current DUTs such as fuel cells and battery cells. This electronic Single Cell load can load a connected voltage source up to 1,200 A at a minimum input voltage of only 600 mV (standard models) or even from 0 V (SCL ZV).

This series is available with a voltage range of 0-12V and 0-40V and suitable for currents of 400A, 800A and 1,200A. For even higher currents, several loads can be connected in parallel in a master-slave configuration. The various models are housed in a compact 19″ housing of only 2 U high.

Of course the SCL series has the standard functions of CC, CV, CR, CP mode. And the combined functions of CC+CV, CR+CC+CV, CP+CC+CV, CV+CC. In addition, these models have a number of functions specifically belonging to high current DUTs. These include determining the internal DC resistance of the connected DUT in accordance with, for example, DIN EN 61951, DIN EN 61960. This SCL series is also equipped with a discharge function, a modulator function in the frequency range from 0.1 Hz … 10 kHz and a datalog function with a time stamp.

For remote operation almost all common interfaces are available. RS-232, USB, LAN, CAN and analogue. GPIB is optional.

"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.”
