What's the best PDU solution for your data center?

Let us break it down for you.




At Server Technology, we understand that power needs vary from customer to customer. Some data centers require all-in-one power solutions complete with all the available bells and whistles, while others have more basic needs. But one thing that doesn't vary is the desire for a best-in-class high quality power product.

Sales Engineer Amanda Senger says Server Technology's large selection of PDUs is a major differentiator among its competitors.

“We're really good at one thing: PDUs. We have over 2,000 different part numbers, where our competitors only have 100-200, so we have a lot more flexibility we can offer our customers."

With so many options to choose from, it's easy to become overwhelmed when deciding which power solution is right for your data center. With this in mind, we've created a handy rack PDU selection wizard and flow chart that addresses all levels of power needs – from basic, non-metered PDUs to Switched POPS with outlet-level power monitoring.

"Ultimately," Senger says, "there's a solution for everyone with Server Technology's PDU lineup. Whether your needs are basic or complex, we offer a solution for you. Even if you don't need power monitoring, you're probably still going to want a high outlet count in a high-quality PDU."

Outlet Level Monitoring

Do you need outlet level monitoring?


POPS - Per Outlet Power Sensing

POPS® (Per Outlet Power Sensing)
Monitor Current Load (A), Voltage (V), Power (W), Apparent Power (VA), Crest Factor, Power Factor, and Energy per outlet.


The All-In-One POPS rack PDU is the right choice for your data center if you want outlet-level power monitoring. POPS is the perfect feature for those who need to understand how much power they're using for each device in the data center. POPS PDUs are available with or without outlet-level ON/OFF control.

Individual Outlet Control

Do you need individual outlet control?


Individual Outlet Control

Outlet Control
On Switched PDUs, cycle power to individual outlets or groups of outlets to reboot servers. Or, power off unused receptacles.


The Switched rack PDU is the right choice for your data center if you want outlet-level ON/OFF control. Switched outlets are the perfect feature for those who need to reboot locked-up devices whether down the hall or thousands of miles away. Switched PDUs are available with or without outlet-level power monitoring.
