EA-ELR 10080-120 2U Programmable DC Electronic Load with Energy Recovery

The EA-ELR 10080-120 2U is a state-of-the-art programmable DC electronic load, also known as an Energy Recovery Load or Recuperating Electronic Load. This 3000W DC Load is engineered to sink up to 120A from DC sources with a voltage range of 0-80V, offering a highly efficient and cost-effective testing solution. Its standout feature is the advanced energy recovery function, which feeds up to 94% of the absorbed DC power back into the local AC grid with a power factor of approximately 0.99, significantly reducing operating costs and heat dissipation. The load delivers exceptional dynamic performance with a rise and fall time of ≤10ms, making it suitable for testing power supplies, batteries, and renewable energy components. It ensures precise measurements with a voltage accuracy of ≤0.05% FS and a current accuracy of ≤0.1% FS. The intuitive 5-inch color touchscreen, versatile analog/digital interfaces (USB, Ethernet, optional modules), and robust features like a built-in function generator, battery test, and MPP tracking for solar panels make it an indispensable tool for R&D, QA, and production environments.
