Home » H&H PLA series DC loads
The H&H PLA series DC loads is a range of electronic loads, suitable for voltages from 60Vdc to 800Vdc and currents from 2A to 120A. The H&H PLA series is available in a 200W, 400W, 800W and 1500W version, with CC – CV – CR – CP modes. All measured values are clearly legible from the illuminated display. In addition, this series is standard equipped with an analog I/O port and Ethernet + USB + RS-232 + CAN, Also, GPIB interfaces are optionally available.
Variable load profiles (Dynamic operation) are easily configurable up to 100 steps. With the standard data acquisition feature, data logging is possible, for example, for generating waveforms or characteristics, including time, voltage and current values. Furthermore, the PLA series is suitable for testing solar panels. You can also adapt the series for testing MPPT trackers. The use of temperature-controlled low noise fans also limits the noise level of this electronic load.
Evidently, the PLA load protects against excessive currents, power, and temperature. There is an indicator for reverse polarity, excessive voltage and excessive voltage (for the powered-on current).
For applications of this electronic DC load consider Power Supply testing, Battery testing, ACCU or Fuel Cell testing. Or in DC Solar power networks and with Electrical Vehicle (EV) testing. By default, a dynamic load feature is available in the PLA series. More advanced load profiles can be realized in combination with, for example, an arbitrary function generator. For the H&H PLA series DC loads there are also various software tools available as well as Labview drivers.

"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.”
