Description

The new series of compact electronic DC loads, called EA-EL 9000 T, offers three tower models for the daily application in research laboratories and also schools or similar educational facilities. The low power ratings allow for a multitude of test applications while being cost effective and space saving.

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 remote control of the devices via analog or digital interface have been improved by an ARM processor controlled hardware, compared to older electronic load series. An USB port is standard with this series, Ethernet and analog interfaces can be optionally retrofitted by the user. All interfaces are galvanically isolated.
