EA Elektro-Automatik ELR91500-30 DC Electronic Load

The EA Elektro-Automatik ELR91500-30 is a highly versatile DC electronic load, optimized for a wide array of applications, featuring innovative energy recovery technology. Designed for efficiency, this cutting-edge device offers four standard regulation modes: Constant Voltage (CV), Constant Current (CC), Constant Power (CP), and Constant Resistance (CR).

At the heart of the ELR91500-30 is a powerful FPGA-based control circuit, which not only enhances operation but also incorporates advanced functionalities such as a built-in function generator. This allows for sophisticated tests and simulations of non-linear internal resistances, which are particularly beneficial in applications involving batteries and LED circuits.

One of the standout features of the ELR91500-30 is its energy recovery capability, which intelligently converts supplied DC energy into a synchronous sine current and returns it to the local grid. This unique feature minimizes heat dissipation and contributes to significant energy savings, making it a smart choice for organizations looking to reduce operational costs.

The user-friendly experience is elevated by a large color TFT touch panel, providing a more intuitive manual operation compared to other electronic load series on the market. This model is available in configurations tailored to different power requirements: the US version operates on a 208 V (L-L) two- or three-phase supply, while the EU version is suitable for one to three phases at 230 V (L-N).

With its FPGA-based digital function and arbitrary generator, the ELR91500-30 allows users to create custom load profiles. It can generate waveforms including sine, square, sawtooth, and ramp functions in any sequence, all managed by a comprehensive digital value table containing up to 3276 points. This flexibility is invaluable for simulating non-linear internal resistances, making it ideal for extensive battery testing and operational analysis.
