EA-ELR 10200-210 3U Programmable Electronic DC Load with Energy Recovery

The EA-ELR 10200-210 3U is a 15 kW regenerative electronic DC load from the ELR 10000 Series, designed for demanding laboratory and industrial testing applications. It functions as a high-power, programmable sink capable of dissipating up to 15,000W (9,000W when derated on a 208V AC supply) and can handle voltages from 0 to 200V and currents from 0 to 210A. Its standout feature is energy recovery (recuperation), which converts consumed DC power back into AC with up to 94.5% efficiency and feeds it back into the local grid, significantly reducing operating costs and heat output. Equipped with a 5-inch color touchscreen, integrated function generator (including sine, triangle, rectangle, trapezoid, DIN 40839, arbitrary, and battery test functions), and MPP tracking for solar panel testing, it offers unparalleled versatility. Standard interfaces include USB, Ethernet, and an isolated analog port, with optional digital bus modules (CAN, Profibus, Profinet, etc.) available. It supports master-slave parallel operation for systems up to 960 kW, making it an ideal solution for testing power supplies, batteries, power semiconductors, and renewable energy components.
