Home » LDH400P electronic load up to 500V from TTI
The LDH400P electronic load of TTi is an extension in the product range of TTI in the segment DC loads. The LDH400P is suitable for testing and characterizing a wide range of DC power sources. The load can be used to investigate the behaviour of many different types of power sources such as PFCs, batteries and solar cells, as well as electronic power supply units. The wide voltage/current range, the various functions and the built-in current generator offer a versatility of testing solutions for R&D laboratories up to component testing.
This load can be loaded up to a maximum power of 400 W. The maximum current is 16 A and the maximum voltage is 500 V. The LDH400P load can operate in constant current (CC), constant power (CP), constant resistance (CR), constant voltage (CV) and constant conductance (CG) mode. The LD400P has a variable duty cycle transient generator for dynamic loading of the DUT. Switching between the two pre-set load levels can be done between 0.01 Hz and 10 kHz and within all functions. These two levels can be set with high precision.
It is often important to follow the waveform of the current. The LD series offers a calibrated monitor output for this purpose. This can also be used as a synchronization for the transient generator. Some loads, such as rechargeable batteries, can be damaged if the output voltage drops below a certain level. With the LDH400P this can be protected: the current is quickly regulated to zero when the voltage drops below a preset value.
The load inputs of the LDH400P are classified according to CAT II (300V). This simplifies direct testing of PFCs and connected power supplies with the LDH400P. By eliminating the need for an isolation transformer, this saves space and costs.
The LD series offers analogue control for all functions. An IVI driver for Windows is included with all P models in the LD series. The LDH400P can also be controlled via USB, RS-232, GPIB and LAN interfaces isolated from the output.

"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.”
