What's the best rack 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."

Amanda Senger
Sales Engineer, Server Technology

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."

Switched Per Outlet Power Sensing PDUs feature highly accurate, outlet-level power monitoring for your data center power needs. Switched POPS PDUs are expandable and offer optional temperature and humidity probes. They also feature rack level power management, input power monitoring, environmental (temperature and humidity) monitoring, outlet groups and alarms.

With Per Outlet Power Sensing, you can see measurements for load (in amps), voltage, active power, apparent power, crest factor, power factor and power consumption (measured in W-hrs). Certain models also feature retractable fuse or breaker branch circuit protection. With POPS technology, outlets may be linked to one or multiple groups without loss of control of that individual outlet. SNMP trap email alerts give you automated warnings for power and environmental conditions. POPS units are also expandable, with the ability to add additional outlets through the link unit without additional IP address. The optional humidity and temperature probes are attached to 10-foot cords that allow for measurements in various locations within the cabinet. You can then view the values from the rack PDU interface or send out trap email alerts to warn when certain thresholds have been met or exceeded.

Switched PDUs from Server Technology also feature outlet lock-out, power-up sequencing to reduce power-up inrushes and optional smart load shedding. Not only do Server Technology's Switched PDUs feature Smart PDU abilities for network access to power and environmental information, but these rack PDUs also give outlet control for reboot of locked-up devices as well as power-up sequencing.

Switched PDUs are designed to be perfect for all environments that require power + environmental monitoring, power-up sequencing, rebooting, scheduling power loads, and interoperability with Server Technology's award-winning Sentry Power Manager software for data centers. These Switched PDUs have been especially useful in rapidly growing environments, such as those found in colocations.

Server Technology Switched PDUs can be purchased with our award-winning High Density Outlet Technology (HDOT) and Alternating Phase technology. With HDOT, you get the highest outlet count in the most compact form factor of any PDU on the market. Alternating phase outlets alternate the phased power on a per-outlet basis rather than a per-branch basis. This design allows for shorter cords, faster installation and easier load balancing for 3-phase rack mount PDUs.
