The Data Center Power Distribution Unit (PDU) is a critical part of data center infrastructure. A PDU provides electrical power to the server racks and various other components in the data center. The selection of the proper PDUs is critical because they are a significant part of the data center’s reliability, efficiency, safety, and security. This guide will provide best practices for selecting, installing, and maintaining PDUs.

What is a Data Center Power Distribution Unit

A Data Center Power Distribution Unit (PDU) is an electronic device used to monitor and control the power to a rack of servers. This allows the user to switch on or off power to the server remotely and provides much-needed monitoring and automation of power distribution.

In the world of data centers, many different types of equipment need to be plugged in and powered on, meaning numerous power outlets must be controlled and distributed throughout the space. Each branch PDU allows administrators to manage the outlet at both ends of the branch, while an in-row PDU can spread this control throughout a row of racks or cabinets where multiple devices plug into it.

The primary difference between these types is their physical design. Branch models tend to be larger and heavier than in-row; they are meant for areas with enough room to be set up side by side on the floor, such as at the end of a row of racks or cabinets. In-row PDUs, on the other hand, is designed to sit within the row itself, and they typically have smaller footprints than branch units; they are used when there isn’t enough space between equipment racks/cabinets for full-sized units.

These units are typically installed in areas where there are many collection points for electricity, such as in a data center or similar facility. They are also used as part of a backup generator setup as they can distribute AC and DC electricity.

Choosing the right Data Center PDU for your environment

The power Distribution Unit (PDU) is an integral part of a data center building. It is used to distribute power from the power sources to different branches of the data center for connection with various devices. PDU manufacturers need to design reliable and safe products for customers. A suitable PDU should be of good quality and can reduce the failure rate.

Choosing the right data center’s power distribution unit (PDU) for your needs is more critical than many IT professionals realize. Even though PDUs are often overlooked and relegated to a corner of the data center, they can impact the overall operation of your facility.

Each data center has its unique power requirements. The number of racks, the number of spaces per rack, and the rack space layout determine how much power will be needed. The amount of IT equipment housed in each room determines how much current will be required. You also have to consider existing infrastructure and whether or not you need redundancy.

To help you make the best decision for your setup, consider the following factors:
  • Line Interactive vs. Standby?
  • Circuit breaker size?
  • How many circuits do you need?
  • How many outlets per circuit?
  • Does temperature matter?

A typical DC PDU will have several features. It will have an input on the back to connect it to the primary AC source. This can be an electrical generator or an AC outlet that provides power to the building. The DC PDUs will also contain several outputs for connecting various devices. There will usually be multiple power outlets that are used for connecting servers and network switches, as well as USB ports that can be used with small devices like phones, tablets, and laptops.

Other ports may include serial connections or Ethernet networks which provide more security than USB connections when transmitting data over the Internet. Finally, the DC PDU can give enough current in each port to ensure that your equipment operates appropriately without overloading any one outlet’s capabilities.

Configuring your Data Center PDU

The primary purpose of a Data Center PDU (Power Distribution Unit) is to provide power to multiple pieces of equipment. However, quite a few features added to this simple function make them very important for any data center. First and foremost, they have to distribute power evenly between all connected devices without losing voltage or putting any strain on the main line. They also need to be able to monitor the overall load and ensure that everyone has enough power at all times.

One feature often included with a Data Center PDU is remote monitoring by SNMP (Simple Network Management Protocol), allowing you to monitor your Data Center from anywhere via the Internet using specialized software.

A Data Center Power Distribution Unit (PDU) is a device that distributes power from one source to multiple pieces of equipment. Depending on the capabilities of your unit, a single PDU can provide power to many devices and outlets, such as computers, power distribution units, network equipment, and monitors. The most important thing is overloading a circuit with only a few devices drawing power. This will cause your alarm panel to go off and trip the circuit breaker. In most cases, it is best to adhere to UL guidelines for the number of devices you can plug in per circuit.


While a data center PDU is a critical piece of electrical equipment required to ensure proper power distribution, you should also install one that best serves your particular needs. There are plenty of factors to consider, but by taking the time to evaluate them, you can be sure that you’re making an educated choice and getting the most out of your next data center PDU purchase.

You can configure a fully functional DC PDU as an offline device or utilize it as part of a Network Management System’s fault monitoring function. A fully functioning PDU is essential for most applications, regardless of your chosen route.

A data center power distribution unit is one of the tools for saving energy in a data center. It is crucial for reducing emissions in the data center. Visit us to learn more about powerful data center power distribution units and their application in detail.
