EA-ELR 10080-1000 4U 30kW Programmable DC Electronic Load with Energy Recovery

The EA-ELR 10080-1000 4U is a high-performance programmable DC electronic load designed for precision testing of power supplies, including 24V power supplies, DC power supplies, and bench power supplies. With a voltage range of 0-80V, current up to 1000A, and power up to 30kW, this load features energy recovery that recycles up to 95.5% of absorbed DC energy back to the grid, reducing operating costs and heat dissipation. It offers exceptional regulation accuracy: constant voltage (CV) at ≤0.05% FS, constant current (CC) at ≤0.1% FS, constant power (CP) at ≤0.3% FS, and constant resistance (CR) at ≤0.3% FS + 0.1% FS. The load delivers fast dynamic response with current rise and fall times of ≤2ms, ideal for transient testing. It includes multiple interfaces such as USB for data logging, Ethernet for remote control, a 15-pin analog interface, and optional modules for CANopen, RS232, Profibus, and more. Advanced functions include a built-in function generator, battery testing, MPP tracking for solar panels, and master-slave parallel operation for scalable power up to 1920kW. Designed for industrial use, it supports air or water cooling and meets safety standards with protections like OVP, OCP, OPP, and OT.
