Data Center Power Infrastructure

Precise Measurement and Validation Across the Entire Data Center Power Chain

Modern AI and hyperscale data centers rely on increasingly complex power infrastructure to support high-density compute, GPU acceleration, and rack-scale power delivery. From utility input and UPS systems to 48V rack architectures, server PSUs, and high-current busbars, engineers must validate efficiency, reliability, and dynamic power behavior across the entire electrical chain.

We provide precision power measurement and synchronized analysis solutions for data center PSU validation, server power analysis, rack-scale power measurement, and power electronics testing. 

Common Challenges:

Workloads create rapidly changing power demand profiles that are difficult to capture using conventional instrumentation. High-current architectures, wide-bandgap power electronics, and dynamic GPU loading introduce fast transients, harmonics, and switching behavior that require precise synchronized measurement.

• Capturing power spikes and transient load behavior
• Measuring high-current rack and busbar systems
• Validating dynamic load response testing
• Analyzing ripple, noise, and harmonics
• Synchronizing measurements across multiple power domains
• Achieving traceable accuracy for efficiency testing
• Meeting evolving energy-efficiency standards
