Electronic Loads

Programmable Electronic Loads

Our programmable electronic loads are composed of an optimum mix of analogue- and digital technology (µ-controller/FPGA based). By combination of standardised electronic platforms out of a modular structure, we generate a large portfolio of electronic-load series, perfectly adapted in power, function, performance and cost to the numerous applications in industrial environment and R&D.

EA programmable electronic loads are available in conventional technology (heat dissipating) and as “regenerative”loads. The latter allows, specifically under long-term testing condition (e.g. battery discharging) a full amortisation of its invested value by its energy-saving capability, similar as with Photovoltaic installations.
