EA-ELR 21000 Dynamic Test System

The ELR 21000 dynamic test system, featuring the new EA Elektro-Automatik high-speed regenerative electronic load ELR 21000-80 device, enables engineers to validate real-world rack-level power behavior under dynamic conditions—while dramatically reducing lab energy consumption, heat, and infrastructure requirements.

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

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.
