EA Elektro-Automatik EA-ELR 10200-25 2U Regenerative DC Load

Overview

The EA Elektro-Automatik EA-ELR 10200-25 2U is a compact programmable regenerative electronic DC load in 2U rackmount format. With 1.5 kW power rating and 200 VDC, 25 A output, it accepts single-phase 110-240V AC input with active power-factor correction. The unit recovers dissipated power and returns it to the grid with greater than 95% efficiency, reducing heat generation and operational costs while minimizing noise.
