Home » ERI series DC loads from Höcherl&Hackl
Höcherl & Hackl has expanded its product portfolio with a series of regenerative DC loads; The ERI series DC loads.
The ERI series DC loads comprises three performance classes from 3600 W to 10800 W. In addition to the standard modes (constant current, constant voltage, constant voltage, constant power and constant resistance), these DC loads can also work in CCV mode (constant current up to a certain voltage level) and CVC mode (constant voltage up to a certain current level). Voltage and current limit values are adjustable. Six models are available with a voltage increasing from 120 V / 330 A to no less than 400 V /135 A. Efficiency is about 95%.
It is also possible to carry out dynamic loads using a list of up to 300 setpoints. In addition to logging the measurement data via all digital interfaces, it is also possible to store the data on an external USB flash drive. There is a wide range of interfaces as standard: Ethernet, USB, RS-232, analog I/O and CAN.
Optionally, they are the insulated analog I/O interface and the GPIB interface.
Programming may be done by means of a SCPI command set, but H&H also provides extensive software packages for controlling the ERI series DC loads as standard. This ranges from simply changing all settings to a list mode with all dynamic tests. Labview drivers are also available.
The advantages are clear: the recycling of energy is of course better for the environment than converting this energy into superfluous heat.
And it often goes a step further. This excess heat usually has to be removed by air conditioning.
The energy saving is therefore much greater if only the energy delivered back to the grid. For large capacities, the lighter grid connection is also often an additional financial advantage.
(Note: there are restrictions attached to returning energy to the grid.)

"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.”
