SiC Technology Delivers Highest Power Density ELR

News

4U rack-mounted DC load requires as little as half the rack space for the same power output as competing programmable loads

Elektro-Automatik, a maker of automated test equipment for power electronics products and systems, has announced a 30 KW Programmable Electronic Load (ELR) that uses SiC power conversion devices to deliver the industry's best power density

Thanks to advances in SiC technology, the 4U rack-mounted ELR 10000 4U requires as little as half the rack space for the same power output as competing programmable loads.

This latest generation ELR combines its high-efficiency programmable DC load with an equally efficient inverter (regenerative) output stage, returning up to 95 percent of the energy used in the test back to the ac grid. A master-slave bus provides for parallel connection of multiple ELR 10000 units to a maximum input power rating of 1080 KW.

“The high-power density, parallel operational capability and regenerative load feature of the ELR 10000 provides an exceptional solution to large-scale systems testing in automotive, solar and large-scale power supply burn-in applications,” says Eric Turner, Elektro-Automatik USA's sales and marketing manager. “The remarkable efficiency provided by the regenerative output dramatically reduces the heat losses and environmental energy costs.”
