EA Elektro-Automatik ELR9500-60 DC Electronic Load
The EA Elektro-Automatik ELR9500-60 is a state-of-the-art electronic DC load that integrates advanced energy recovery technology, making it a versatile solution for a wide range of applications. Engineered to meet various testing requirements, this device supports four essential regulation modes: Constant Voltage (CV), Constant Current (CC), Constant Power (CP), and Constant Resistance (CR).
Powered by an FPGA-based control circuit, the ELR9500-60 offers added capabilities such as a built-in function generator and a sophisticated table-based regulation circuit. This allows for the accurate simulation of non-linear internal resistances, enhancing its testing versatility.
One of the standout features of this electronic load is its energy recovery function. This innovative technology effectively converts supplied DC energy into synchronous sine current, which can then be fed back into the local grid. This not only minimizes heat dissipation but also contributes to significant energy cost savings.
Designed with user experience in mind, the large color TFT touch panel provides an intuitive manual operation interface that rivals other electronic load series. The device caters to specific regional requirements, with US models operating on a 208 V (L-L) two- or three-phase supply, while the EU variants utilize one to three phases at 230 V (L-N).
Additionally, the sophisticated FPGA-based digital function and arbitrary generator enable users to control and execute highly customizable load profiles. The ELR9500-60 can generate a variety of waveforms, including sine, square, saw tooth, and ramp functions, in any desired sequence. With a programmable digital value table containing 3276 points, this device is capable of accurately reproducing the non-linear internal resistances found in batteries or LED chains. For comprehensive battery testing, the ELR9500-60 is equipped with a dedicated battery test mode, allowing for both constant current and constant resistance discharging.
