Description

The new series of compact electronic DC loads, called EA-EL 9000 DT, extends series EA-EL 9000 T by 10 models in a desktop enclosure to round up the portfolio of electronic loads. It offers new voltage, current and power ratings for a multitude of applications for daily use in laboratories, schools or workshops. All models support the four regulation modes constant voltage (CV), constant current (CC), constant power (CP) and constant resistance (CR). The core of the control circuit is a fast microprocessor which provides interesting features, such as a true function generator with common functions like sine wave, rectangle or triangle, but also an arbitrary function.

The color TFT touch panel offers an intuitive kind of manual operation, like it is prolific with smart phones or tablet computers. Response times during the control of the devices via analog or digital interface have been improved by an ARM processor controlled hardware, compared to older electronic load series. Digital interfaces, such as USB and Ethernet are standard with this series, as well as an analog one. All interfaces are galvanically isolated. Remote control and implementation into custom applications for every purpose is simplified by the common protocols SCPI and ModBus RTU, as well as by ready-to-use LabView components.
