EA Elektro-Automatik ELR9750-44 DC Electronic Load
The EA Elektro-Automatik ELR9750-44 is a state-of-the-art DC electronic load designed to cater to a vast array of applications. This innovative device features advanced energy recovery capabilities that enhance efficiency while minimizing energy costs. With four essential regulation modes—constant voltage (CV), constant current (CC), constant power (CP), and constant resistance (CR)—the ELR9750-44 offers unparalleled versatility in managing electrical loads.
At the heart of this electronic load is a sophisticated FPGA-based control circuit, which not only facilitates the standard load operations but also includes a robust function generator and a table-based regulation circuit. This functionality allows users to simulate non-linear internal resistances, making it an invaluable tool for testing and development.
The energy recovery feature is particularly noteworthy; it converts the supplied DC energy into synchronous sine current before efficiently feeding it back into the local grid. This process drastically reduces heat dissipation and contributes to significant energy savings.
Equipped with a large, vibrant color TFT touch panel, the ELR9750-44 offers an intuitive interface that sets it apart from other electronic load series. The device is compatible with various supply requirements—operating on 208 V (L-L) two- or three-phase for US models and 230 V (L-N) for EU models.
A standout attribute of the ELR9750-44 is its digital function and arbitrary waveform generator powered by FPGA technology. This feature allows for the crafting of user-customizable load profiles, enabling the generation of sine, square, saw-tooth, and ramp waveforms in any desired sequence. The device incorporates a freely programmable digital value table with up to 3276 points, making it ideal for simulating non-linear internal resistances typically found in batteries or LED chains. Additionally, its dedicated battery test mode accommodates a range of tests including constant current and constant resistance discharges.
