Data centers support the world’s most demanding applications, from AI to hyperscale cloud infrastructure. From utility input to server power rails, cooling systems, and high-speed optical links, Yokogawa helps engineers validate efficiency, reliability, and thermal performance in modern AI and hyperscale data centers.
Yokogawa provides precise, reliable end-to-end measurement solutions that help data centers ensure clean, reliable, and efficient power delivery from the utility grid through backup systems, distribution, server electronics, and cooling.


At a system level, data centers operate across two primary engineering domains:
These domains are tightly coupled. Changes in compute workload directly impact power demand, including the energy required to support cooling systems, energy efficiency and overall data center resiliency.

Test and validate server PSUs, rack power systems, GPU workloads, UPS infrastructure, and high-current AI data center power architectures.
Tests and validates high-speed optical and electrical interconnects used in AI, cloud, and data center communication systems.
In a research paper published on IEEE Xplore, Electric Power Research Institute (EPRI) researchers use a Yokogawa Test&Measurement Advanced Digital Power Meter to consistently and accurately measure computer power supply dc output/input voltage, current, power, and power factor.
In a research paper published on IEEE Xplore, researchers from Częstochowa University of Technology and University of Naples Federico II use a Yokogawa Test&Measurement WT310 Digital Power Analyzer to attain accurate and reliable power and energy measurements from the ccNUMA/SMP system.
