Electronic DC Loads

The new series of compact electronic DC loads, called EL 9000 B, offers new voltage, current and power ratings for a multitude of applications. All models support the four common regulation modes constant voltage (CV), constant current (CC), constant power (CP) and constant resistance (CR). The FPGA based control circuit provides interesting features, such as a function generator with a table based function for the simulation of nonlinear internal resistances. The relation between power consumption and height of the devices has been significantly increased. With only 3U height for all models and the capability of consuming DC power of up to 7.2 kW per unit the height has been reduced to half. The large color TFT touch panel offers an intuitive kind of manual operation, such as it is prolific nowadays with smartphones or tablet computers.
