EA Elektro-Automatik ELR9250-70 DC Electronic Load
The EA Elektro-Automatik ELR9250-70 is an advanced electronic DC load featuring innovative energy recovery capabilities. Perfect for a wide range of applications, this device supports four essential regulation modes: constant voltage (CV), constant current (CC), constant power (CP), and constant resistance (CR). Designed with a robust FPGA-based control circuit, it offers additional functionalities, including a built-in function generator and a table-based regulation circuit that simulates non-linear internal resistances.
One of the standout features of the ELR9250-70 is its energy recovery function. This technology efficiently converts supplied DC energy into synchronous sine currents, which are then fed back into the local grid. This capability not only minimizes heat dissipation but also significantly reduces energy costs.
The device is equipped with a large color TFT touch panel, providing an intuitive manual operation experience that exceeds traditional electronic loads from competitors. For users in the US, the ELR9250-70 operates on a 208 V (L-L) two- or three-phase supply, while its EU counterpart requires one to three phases with 230 V (L-N).
An added benefit of this model is the FPGA-based digital function and arbitrary generator, which allows for control of user-customizable load profiles. It can generate sine, square, sawtooth, and ramp functions in any desired sequence. With a programmable digital value table containing 3,276 points, the ELR9250-70 effectively reproduces non-linear internal resistances typical of batteries or LED chains. For battery testing needs, the device features a dedicated battery test mode, accommodating constant current or constant resistance discharging methods.
