EA Elektro-Automatik EA-ELR 10080-510 3U Regenerative Electronic Load

Overview

The EA Elektro-Automatik EA-ELR 10080-510 3U US208V is a programmable regenerative electronic DC load optimized for three-phase 208V AC mains in North American industrial environments. With 15 kW power handling at 80V/510A, this 3U rackmount unit recovers consumed energy and feeds it back to the grid with over 96% efficiency. This regenerative approach eliminates heat dissipation costs inherent in traditional electronic loads.

The autoranging input stage automatically adjusts to varying DC voltage and current conditions while maintaining high efficiency. Master-Slave parallel connectivity enables configuration of larger test systems combining up to 64 units.
