The Cinergia EL series DC loads is characterized by the 4-quadrant concept. This ensures that the absorbed energy is not dissipated in heat, but returned to the grid. This is why these DC loads are characterized as a regenerative load: the Green electronic taxation.
The EL-DC contains three individual “LOAD” channels, which can be used independently. Parallel use of the three channels creates a single-phase load, suitable for 3 times the maximum current per phase. This electronic load can be operated in Constant voltage (CV), constant current (CC), constant power (CP) or constant resistance (CR) mode.
Within the voltage range of 0-750 Vdc (ch-com) or -350 to +350Vdc (ch-ch), load currents are adjustable from 10Arms to 185Arms in 3 ch mode, 30Arms to 555Arms in 1 ch mode depending on the model. When operating the Cinergia EL series DC load, it is recommended to use the optional isolating transformer to achieve galvanic isolation.
In the Cinergia EL series DC loads the power consumption is converted back into AC voltage and power. Obviously this saves a lot on energy costs. In addition to saving energy from supplied back energy, air-conditioning costs are often also saved by converting power consumption into heat in a traditional set-up. Which consequently needs to be repeatedly compensated with cooling. More important than energy saving is often the connection to the energy grid. Due to the return of energy, a lighter grid connection often is sufficient. This saves considerably on monthly costs and even more when new cables need to be drawn for a heavier connection.
The Cinergia EL-DC regenerative loads have extensive measurement functions and can be operated manually as well as via LAN Ethernet with Modbus/TCP protocol. Optionally, RS485, RS232 or CANbus communication is also possible. The specifically developed Graphical user interface is standard available.
The Cinergia EL-DC series regenerative loads consist of the following models:
The Cinergia EL series also contain EL-AC and EL AC+DC models.

"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."
University of Luxembourg
“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.”
