EA-ELR 10200-420 4U 30kW Programmable DC Electronic Load with Energy Recovery

The EA-ELR 10200-420 4U is a high-performance, energy-recovering programmable DC electronic load, part of the EA-ELR 10000 4U series. This 30kW Electronic Load is engineered for demanding test applications, featuring a wide voltage range of 0-200V and a high current range of 0-420A, making it an ideal 200V DC Load and 420A Electronic Load solution. It boasts an impressive efficiency of up to 95.3% due to its advanced energy recovery system, which feeds up to 95.3% of the absorbed energy back into the local grid, significantly reducing operating costs and heat dissipation. The load is equipped with a 5-inch Color TFT Touch Screen for intuitive operation and control. With an input capacitance of 5400µF, it ensures stable performance under dynamic loading conditions. Key functionalities include multiple operating modes (CV, CC, CP, CR), a built-in function generator for complex waveforms, battery testing, MPP tracking for solar panel simulation, and master-slave parallel operation for scaling up to 1920kW. It offers extensive remote control options via USB, Ethernet, analog interface, and optional digital interface modules (CAN, Profibus, etc.), making it a versatile and powerful tool for testing power supplies, batteries, and renewable energy components.
