Description

This 2017 released series of compact electronic DC loads called EA-EL 3000 B is the second generation of small desktop loads with a DC power capability of 400 W. It offers useful voltage and current ratings for a multitude of applications and 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 software based function generator with common functions like rectangle, triangle or ramp. The color display, together with a keyboard and two rotary knobs provides the user an intuitive kind of manual operation and better overview.

Response times during device control via analog or digital interface have been improved by an ARM processor controlled hardware, compared to older electronic load series.
