Introduction H&H PLA series load models 800 W and 1200 W
H&H has expanded their low power PLA loads’ power palette with 800 W and 1500 W models. The electronic loads of the H&H PLA series combine classic design, large display with modern interfaces and great functionality.

Available models, power and voltage classes
The more powerful models have dimensions of 19″ and 2 HU. Just like the 200 W and 400 W models, the new models are available in the voltage classes 60 V, 120 V, 300 V and 800 V. This makes a total 24 different models.

Interface highlights
The highlight of the PLA series is the extensive variety of optional interfaces. In addition to Ethernet, a USB, RS-232 as well as CAN interface can be installed. GPIB is optionally available for 400 W devices. Analog I/O port is standard.

Features
The units provide constant current, constant voltage, constant resistance and constant power modes. In addition, current and voltage protection can be set in any mode. Dynamic operation can be configured up to 100 list point settings. A data acquisition function allows for a 100 measurement points save (time, voltage, current) internally.

The minimum voltage for maximum current is as low as 1.2V. The models up to 300 V have an overload capability. The level and duration of the possible overload depends on the temperature of the power stage. Therefore the units can even be used for a short time for considerably more powerful applications.
Optionally MPPT function for  solar panel test can be activated (option PLA20).

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."

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.”
