ELR 21000 Dynamic Test System

The EA-ELR 21000 Dynamic Test System is a high-speed regenerative electronic load built into a 42U rack for testing next-generation data centre power supplies and power shelves. Configurations scale in 30kW steps from a single 30kW unit to 240kW in one 600mm x 1000mm rack, and up to 1920kW across multiple racks, covering 0-1000V and up to 5120A with a 125% short-term overpower capability. Current slew rates reach 12A/µs at 240kW, and energy absorbed under load is returned to the grid at up to 95% efficiency, cutting heat, cooling demand and running costs. Each rack has a single three-phase AC input, a two-channel emergency stop system with door contact switches, and an arbitrary function generator for programmable voltage and current sequences. Optimised for validating emerging 800V data centre power architectures, with options for water cooling, NS protection and isolation monitoring.
