EA-ELR 10500-60 3U Programmable DC Electronic Load with Energy Recovery

The EA-ELR 10500-60 3U is a high-performance, programmable DC electronic load from the 10000 series, featuring advanced energy recovery technology. This 3U high, 19-inch rack-mount unit is designed for demanding test applications, capable of sinking up to 10000W of power. It operates with a DC input range of 0-500V and can handle currents up to 60A. A standout feature is its regenerative capability, which feeds up to 95.5% of the absorbed DC power back into the AC grid with high efficiency, significantly reducing operating costs and heat dissipation. It supports a wide three-phase AC input (380-480V ±10%, 3ph AC) for full power operation and can also run in a derated mode (6000W) on a 208V AC supply. Equipped with a color TFT touchscreen, integrated function generator, multiple standard interfaces (USB, Ethernet, Analog), and optional digital interface modules, it is ideal for power supply validation, battery testing, solar panel simulation with MPP tracking, and industrial burn-in testing. Its master-slave capability allows parallel operation of up to 64 units for systems with power up to 960kW.
