EA-ELR 11000-80 4U 30kW Programmable Regenerative DC Electronic Load

The EA-ELR 11000-80 4U is a high-power, energy-recovering programmable DC electronic load, also known as the EA-ELR 11000-80 or 80A Electronic Load. This 30kW Regenerative DC Load is engineered for testing high-voltage applications with a wide operating range of 0-1000V and 0-80A. Its advanced energy recovery system operates with up to 95.8% efficiency, feeding most of the absorbed power back into the AC grid to drastically reduce operating costs and heat dissipation, making it an exceptionally efficient Regenerative Electronic Load. It serves as a comprehensive test solution, integrating a Battery Test System for charge and discharge cycling and a Solar Panel MPP Tester for simulating and tracking the maximum power point of photovoltaic modules. The built-in Arbitrary Waveform Generator allows for the creation of complex current or voltage profiles to simulate real-world conditions. For industrial automation environments, it offers optional interface modules to function as a Profibus DP Load, Profinet IO Device, or ModBus TCP Load. With master-slave capability, multiple units can be paralleled to create scalable high-power test systems.
