Introduction H&H ERI Energy Recycling Loads series
H&H has extended their product portfolio with the ERI Energy Recycling Loads series. This series feed the consumed energy back into the local power grid with an efficiency up to 95%.

Advantages
The advantages of the ERI series are clear:
• Energy recycling is better than waste heat
• Lower impact on the environment
• Lower electricity costs
• Pleasant laboratory conditions
• Less air-conditioning
• Silent fans

Available power and voltage classes
The type spectrum contains 3 power classes from 3,600 W to 10,800 W and input voltages of 120 V, 400 V and 800 V.

Features
The units provide constant current, constant voltage, constant resistance and constant power mode.
In addition, protections for current and voltage can be set in any mode. Dynamic operation can be configured up to 300 list point settings. A data acquisition function allows storage of measurement data on an external USB flash drive.

Interfaces
The devices offer an extensive variety of standard interfaces. Apart from Ethernet, USB, RS-232 and a fast I/O Port there is a standard CAN interface. GPIB can be installed as an option (ERI02).
Programming is done in SCPI with an extensive command syntax.

The ERI series load has a sturdy 19“ rack design and can also be used as a table-top device. No additional mounting kits are needed for 19“ rack installation. All connections are located at the rear side. The current terminals are designed as solid copper bars. Covers are supplied as touch protection for units operating with dangerous contact voltages.

Software Tool
The ERI Tool is a graphical software tool to control the ERI series Electronic Loads. The user can choose different functions with the aid of the navigation bar.
The most important load settings are done in the Main Menu (“Settings”). Several graphical widgets inform the user about the measurements and the current device status. Further on, a data logging function can be activated in the Main Menu.

WHAT OUR CUSTOMERS SAY

ABB

"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."

Sasan Rafii-Tabrizi

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.”
