ELR 21000 30kW High Speed

The EA-ELR 21000-80 4U HS is a high-speed regenerative DC electronic load rated at 30kW per 4U unit, with a 0-1000V input range, 0-80A and an overpower feature allowing 125% power for 500ms. Optimised for 800V systems, it delivers current slew rates of up to 1.9A/µs from a single unit and up to 12A/µs with eight units in parallel, while returning consumed energy to the grid at up to 95% efficiency to cut heat, cooling and running costs. Built-in USB, Ethernet, EtherCAT and CAN FD interfaces, Share bus and Master-Auxiliary bus for parallel operation of up to 64 units, and an optional water-cooled variant. It is the building block of the EA-ELR 21000 Dynamic Test System, a modular platform scalable in 30kW steps to 240kW per rack for validating data centre and AI rack power architectures under dynamic load conditions.
