Chroma 63200A series
Chroma has extended their portfolio of Electronic Loads with a range of High Power models in the 63200A series

The Chroma 63200A series high power DC electronic loads are designed for testing a wide range of power conversion products. Applications are: AC/DC and server power supplies, DC/DC converters, EV batteries, automotive charging stations, and other power electronics components. These units can be synchronously paralleled up to 240kW and dynamically synchronized for generating complex multi-channel transient profiles. The 300% peak overpower capability provides extra headroom for fault condition simulations in automotive batteries, fuel cells, and more.

Operating ranges and modes
The 63200A series have three operating voltage choices, 60V, 150V, 600V & 1,200V, with models covering power levels from 4kW to 24kW and up to 2,000A in a single unit.
New complex operating modes include CR+CC, CV+CR and CV+CC modes.  The CR+CC mode is suitable for power on testing and the CV+CR mode can replace Von setting while the CV+CC mode can be used for battery discharge testing. In addition, the unique CZ mode designed in 63200A series can improve the loading behavior of CC & CP mode and makes the simulated loading current more realistic. The 63200A provides this CZ mode to prevent inrush current from occurring and triggering the over current protection of server power. Such cases we find with many capacitors on the mainboard of the pcb such as a computer mainboard.

The DC loads have unique user defined waveform (UDW) capability and external analog modulating input for simulating real-world custom waveforms. Another distinct feature is the dynamic auto-frequency sweep function, which enables detecting a UUTs worst case output deviation across a wide range of current frequencies. In addition, a 255-set of data storage function has been built in for recall of the stored settings at any time. For automated testing, the save and recall functions can save a great deal of time.

Users are able to control the Chroma 63200A family remotely via standard USB or optional Ethernet and GPIB interfaces.

"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.”
