Description

This series of compact electronic DC loads, called EA-EL 9000 B, succeeds the former series EA-EL 9000 A and offers useful 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).

An FPGA based digital control circuit provides interesting features, such as a function generator for arbitrary curves and a table based XY function for the simulation of nonlinear internal resistances. The ratio between power consumption and height of the devices has been significantly increased compared to the former series EA-EL 9000 A. The models with 3U of height are capable of consuming DC power of up to 7.2 kW per unit and the 6U models even twice as much.

The front offers a large color TFT touch panel for an intuitive kind of manual operation, such as it's prolific nowadays with smart phones or tablet computers. In parallel operation of multiple devices, a master-slave bus is used to link multiple units to a bigger system where the actual values are totaled.
