EA-ELR 10200-140 3U Programmable Electronic DC Load with Energy Recovery

The EA-ELR 10200-140 3U is a versatile and efficient programmable electronic DC load designed for comprehensive power testing applications. As a member of the energy-recovering ELR 10000 Series, this model operates over a wider voltage range of 0-200V while delivering a substantial current of 0-140A, resulting in a maximum power handling of 10,000W (derated to 6,000W on a 208V AC supply, full 15,000W for 3U models on 380-480V AC). Its core technology is the regenerative energy recovery system, which inverses up to 94.5% of the consumed DC power and feeds it back into the AC grid, drastically reducing operational energy costs and heat dissipation. The load provides full functionality in Constant Current (CC), Constant Voltage (CV), Constant Power (CP), and Constant Resistance (CR) modes, allowing for precise testing of various power sources, components, and batteries. It is equipped with a sophisticated built-in function generator for creating dynamic test profiles like sine, triangle, rectangular, and arbitrary waveforms, and includes specialized functions for Battery Discharge testing and MPP Tracking for solar inverter and panel evaluation. Supporting master-slave parallel operation for scaling up systems to 960kW, and featuring extensive remote control options via USB, Ethernet, analog interface, and optional bus modules, the EA-ELR 10200-140 3U is an ideal, cost-effective solution for laboratory, industrial, and automotive power testing and validation.
