EA‑ELR100004U is a powerful load system for precise tests of batteries, fuel cells and solar cells. It is capable of dissipating up to 30 kW with high efficiency, returning more than 96% of the energy back to the grid, which significantly reduces the thermal load. Autoranging technology delivers the highest possible power at any combination of voltage and current. In load mode, current, power and resistance stabilization are supported with switching times of less than 2 ms. Built-in safety features include polarity control, active pre-charge, cable voltage drop compensation and instantaneous emergency shutdown. Up to 64 modules can be integrated into a large-scale system with a total power of up to 1.92 MW. With its compact 4U size, high power and energy efficiency, the EA‑ELR100004U is ideal for laboratories and industrial benches with stringent requirements for accuracy, flexibility and reliability.
