Description

The electronic DC loads of series EA-EL 9000 B HP replace the former series EA-EL 9000 HP and reduce the required unit height from former minimum 3U to now only 2U. It means that the steady power of 7200 W of a former EA-EL 9000 HP device can nowadays already be achieved in 6U of height where it required 9U before. The result is a space saving of 33% which allows for achieving even more power in a 19” cabinet.

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 large color TFT touch panel offers an intuitive kind of manual operation, such as it is prolific nowadays with smart phones or tablet computers. Response times for the control via analog or digital interfaces have been improved by the FPGA controlled hardware. In parallel operation of multiple devices, a master-slave bus is used to link the units to a bigger system where the actual values are totaled and the set values distributed.
