The electronic load of the EL9000B series supports the four typical control types: constant current (CC), constant voltage (CV), constant power (CP) and constant resistance (CR). Operation (HMI): Manual operation takes place via a TFT touch panel, two rotary knobs and a button. The large colored display shows all important target and actual values simultaneously and clearly. Furthermore, the entire setup can be carried out via the HMI (Human-machine interface), functions (rectangle, triangle and others) can be configured and much more. The display is multilingual (German, English, Russian, Chinese).
Function generator and table control A special feature is the comfortable, FPGA-based digital function and arbitrary generator, which enables the control of time-running, freely programmable load profiles. Alternating sine and rectangular functions or sawtooth or ramp profiles can be generated. With a freely programmable digital value table with 3276 effective bases embedded in the control loop, nonlinear internal resistances of consumers, such as batteries or LED chains, can be simulated as required.
As standard, two integrated interfaces (1x analog, 1x USB) are available on the back of the devices for remote control, which can be supplemented by optional, plug-in and retrofittable, digital interface modules.
