EA Elektro-Automatik EA-ELR 10200-140 3U Regenerative Electronic Load

Overview

The EA Elektro-Automatik EA-ELR 10200-140 3U is a programmable regenerative electronic DC load designed for higher-voltage test applications. This 3U rackmount unit accepts three-phase AC input from 208-480V and delivers 10 kW at 200V/140A. Operating with regenerative energy recovery at over 96% efficiency, this load significantly reduces costs by eliminating heat dissipation losses typical of traditional electronic loads.

The autoranging input stage maintains optimal efficiency across a wide spectrum of voltage and current combinations. Master-Slave parallel connectivity allows configuration of large-scale test systems by combining up to 64 units for maximum flexibility in power testing applications.
