Top 10: Power Distribution Unit Companies
A power distribution unit (PDUs) is a device for controlling electrical power within a data centre.
This essential component plays a critical role in overall data centre management, as it provides centralised power management and improved uptime. Likewise, the PDU in data centre management can help balance loads and improve energy efficiency for optimum use.
As AI continues to boom, investment is critical to supporting these technologies - particularly when it comes to considering electricity and power constraints.
With this in mind, Data Centre Magazine shares some of the leading PDU companies currently supporting the global industry.
