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 analog or digital interfaces benefit from DSP-controlled hardware. Two USB ports and an analog interface are built-in. There is also a slot for interface modules on the rear side. Pluggable and retrofittable digital interface modules can be purchased separately and include: CANopen, EA-IF-AB-CANO, 801-1272 , Ethernet 1-port, EA-IF-AB-DNET, 801-1275 , Ethernet 2-port, EA-IF-AB-ETH2P, 801-1288 , Profibus, EA-IF-AB-PBUS, 801-1263 , ProfiNet, EA-IF-AB-PNET2P, 801-1281 , RS232, EA-IF-AB-RS232, 801-1269 , ModBus-TCP, EA-IF-AB-MBUS2P, 801-1279 .
