EA Elektro-Automatik ELR9750-22 DC Electronic Load
The EA Elektro-Automatik ELR9750-22 is a cutting-edge electronic DC load designed with energy recovery functionality, making it the perfect solution for a wide range of applications in the modern testing environment.
Key features include four primary regulation modes: Constant Voltage (CV), Constant Current (CC), Constant Power (CP), and Constant Resistance (CR). This versatility ensures that the ELR9750-22 can adapt to various testing requirements.
Equipped with an advanced FPGA-based control circuit, this electronic load offers remarkable capabilities, including a built-in function generator and a table-based regulation circuit that can effectively simulate non-linear internal resistances. This is particularly beneficial for users working with diverse load profiles.
One of the standout features of the ELR9750-22 is its energy recovery capability. This innovative function converts supplied DC energy into synchronous sine current and feeds it back into the local grid, significantly reducing heat dissipation and providing cost savings on energy consumption.
The large, vibrant color TFT touch panel enhances user interaction, offering a more intuitive manual operation compared to conventional models. Designed for flexibility, the US versions operate on a 208 V (L-L) two- or three-phase supply, while the EU models can accommodate one to three phases with a voltage of 230 V (L-N).
The ELR9750-22 also features an FPGA-based digital function and arbitrary generator, allowing for the execution of customizable load profiles. Users can generate sine, square, sawtooth, and ramp functions in any desired sequence, bolstered by a programmable digital value table with 3,276 points for precise replication of non-linear internal resistances, like batteries or LED chains.
Additionally, for testing various battery types, including constant current or constant resistance discharging, the ELR9750-22 comes equipped with a dedicated battery test mode, facilitating comprehensive performance evaluations.
