EA-ELR 9000 3.5kW - 10.5kW Series Electronic Loads with Energy Recovery

The Elektro-Automatic EA-ELR 9000 Series of electronic DC loads with energy recovery offers new voltage, current and power ratings to facilitate wide-ranging application. These devices incorporate the four common regulation modes of constant voltage, constant current, constant power, and constant resistance.

The FPGA-based control circuit provides additional features. The electronic load does not dissipate energy extracted from a DC source to ambient. It recovers energy extracted from a DC source and feeds back more than 90% of this energy into the AC grid (inverter/recovery function). This reduces drastically the electricity bill and eases the heat management inside a burn-in facility - reducing or even waiving investment in temperature-conditioning equipment, which is also a substantial electric energy consumer. These recovery e-loads are up to three times smaller than a conventional heat-dissipating e-load.

The large blue LCD touch panel offers a different and intuitive style of manual operation. Response times for control via analogue or digital interfaces benefit from DSP-controlled hardware. Two USB ports and an analogue interface are built in. There is also a slot for interface modules on the rear side.
