High-dynamic, regenerative test solution for next-generation data centers

The ELR 21000 dynamic test system combines EA regenerative electronic loads and application expertise into a modular, scalable test platform optimized for data center power electronics.

At the core of the system is the EA-ELR 21000-80 high-speed regenerative electronic load, designed to reveal real-world power behavior in modern data center architectures. 

  • Total DC power up to 240 kW per rack
  • Scalable in 30 kW steps
  • Dynamic load transitions directly at 800 V DC
  • High current slew rate up to 12 A/µs at 240 kW
  • Regenerative system with efficiency up to 95%
  • Modular, service-friendly design

Regenerative operation for energy-efficient testing 

Recover test energy back to the grid instead of dissipating it as heat. Regenerative operation helps reduce lab power demand, cooling needs, and operating costs.

 

Up to 95% energy recovery

  • Drastically reduced lab heat and noise 
  • Lower HVAC requirements and operational cost 
  • Reduces grid power demand – only system losses are drawn from the grid
Example of potential energy recovery using a high power regenerative electronic load
Multiple high-speed regenerative electronic loads combine to make the ELR 21000 Dynamic Test System

Scalable, compact rack-level power 

Scale from 30 kW modules to rack-level and multi-megawatt systems as test requirements evolve. Compact, high-power-density hardware helps reduce floor space and installation complexity. 

  • Modular expansion in 30 kW steps
  • Up to 240 kW per rack, expandable to multi-megawatt systems
  • High power density minimizes floor space
  • Supports high-power testing in infrastructure-limited labs
  • Reduces installation risk and helps accelerate time to market

Why Tektronix and EA

Unlike conventional dissipative load solutions, the ELR 21000 dynamic test system:

  • Enables realistic system-level testing at full voltage
  • Dramatically lowers CAPEX and OPEX
  • Reduces installation risk and facility constraints
  • Scales alongside evolving data center power architectures

The result is higher confidence, lower operating costs, and faster deployment of next-generation data center power systems.
