EA-ELR 10750-60 3U Programmable DC Electronic Load with Energy Recovery

The EA-ELR 10750-60 3U is a high-power, regenerative DC electronic load designed for demanding test applications in R&D, quality assurance, and production environments. It features advanced energy recovery technology that converts up to 95.5% of the absorbed DC power back into the AC grid with high efficiency, significantly reducing operating costs and heat dissipation. With a wide DC input range of 0-750V, a maximum current of 60A, and a powerful 15000W rating (9000W in derated mode at 208V AC), this unit is a versatile solution for testing power supplies, batteries, solar inverters, and automotive components. It operates in Constant Current (CC), Constant Voltage (CV), Constant Power (CP), and Constant Resistance (CR) modes. A comprehensive built-in function generator supports a wide array of waveforms, including sine, triangle, rectangle, trapezoid, and arbitrary sequences, and includes specialized functions for DIN 40839 automotive simulation, MPP tracking for solar panel testing, and detailed battery charge/discharge tests. Remote control is facilitated via USB, Ethernet, and an isolated analog interface, while the master-slave capability allows parallel operation of up to 64 units for scalable, high-power systems. Housed in a standard 3U 19-inch rack form factor, it meets stringent safety standards including EN/IEC/UL 61010-1.
