PDU and socket
A power distribution unit (PDU) is a device fitted with multiple outputs designed to distribute electric power, especially to racks of computers and networking equipment located within a data center. Data centers face challenges in power protection and management solutions. This is why many data centers rely on PDU monitoring to improve efficiency, uptime, and growth. For data center applications, the power requirement is typically much larger than a home or office style power strips with power inputs as large as 22 kVA or even greater. Most large data centers utilize PDUs with 3-phase power input and 1-phase power output. There are two main categories of PDUs: Basic PDUs and Intelligent (networked) PDUs or iPDUs. Basic PDUs simply provide a means of distributing power from the input to a plurality of outlets. Intelligent PDUs normally have an intelligence module that allow the PDU for remote management of power metering information, power outlet on/off control, and/or alarms. Some advanced PDUs allow users to manage external sensors such as temperature, humidity, airflow, etc.
Rack PDU Components Explain
Power distribution units (PDUs) are an essential part of the IT infrastructure, PDUs bring electricity from a utility power source, generator, or uninterruptible power supply (UPS) to the racks and cabinets distributed throughout the data center.
Some PDUs are designed to mount horizontally in a rack, while others mount vertically in the "zero U" space of the enclosure.
There are specific PDUs for single-phase and three-phase power sources and different voltages.
Metered PDUs measure the amperage to prevent overloading. This can be done at an individual outlet level or collectively.
"Smart" PDUs (also known as "intelligent" PDUs) connect to the network to enable remote monitoring of input and output voltage, amperage, kilowatts consumed, and other information.
Switched PDUs allow administrators to control outlets collectively or individually.
PDUs also have different types of plugs, receptacles, and power cords to meet various requirements. A basic understanding of these components is essential to selecting the right PDU for your environment.
PDU Plug or Input Connector Types
One of the first things to determine when choosing a PDU is what PDU connector or plug types your configuration calls for. Input connectors, or plugs, attach the PDU to the input power source. In essence, the PDU plug needs to match the receptacle. The International Electrotechnical Commission (IEC) and National Electrical Manufacturers Association (NEMA) have established standards for plug and receptacle types, which are designated by codes.
IEC 60320 are some of the most commonly used connectors. These include the C13, C14, C19, and C20 plugs.
IEC 60309 connectors are used in industrial environments. They are designated by the configuration of pole (P), earth/ground (E) and neutral pins — for example, 2P+E, 3P+E and 3P+N+E. Yellow fittings are generally for 100V to 130V, blue for 200V to 250V, and red for 380V to 480V.
NEMA connectors are designated by P for plug and R for receptacle (socket). Common types of plugs are 5-15P and 5-20P, L5-20P and L5-30P, L6-20P and L6-30P, L15-20P and L15-30P, and L21-20P and L-30P. The L indicates a locking plug.
What A Power Distribution Unit Does: Understand the Key Features

What are the Different Types of Sockets in Power Distribution Unit?
A power distribution unit or PDU has enhanced the capability of a IT Industry. Hence, it is a critical part of the industry since it cannot afford outage or damage of business-critical equipment even for a short duration.
Growing need for PDUs
A PDU becomes an anchor to a server room where electrical sockets or related outlets are far away from where equipment is placed. The PDUs ensured that power was distributed stable and controlled to all the IT equipment within the IT environment. A basic PDU consists of one input and multiple outputs connected to different equipment in the server room. These PDUs have either input open or fixed with Indian/IEC Plugs.
Importance of various socket configurations
Thorough market research brought to the forefront the industry requirement, and accordingly, the PDUs are designed with a few basic types of sockets configurations such as;
Indian 5A rated at 5A/250V
Indian 5/15 rated at 15A/250V
Intel Multi pin rated at 6&13A/250V
IEC Sockets rated at 10&13A/250V
UK Flat Pin rated at 13A/250V
However, other socket configurations are offered as a solution to specific needs. The metered PDUs are manufactured with an inbuilt reliable Circuit board with a digital display showing details about the power supplied. It is a perfect blend of conventional and intelligent PDU that ensures zero overloading and MCB tripping.
Common Types of PDU
Switched PDUs and metered PDU unis are two of the most common types of power distribution units.
Metered PDUs provide network-grade power distribution. Switched PDUs also provide network-grade power distribution, but also remote monitoring and outlet control.
Switched PDUs make it possible for you to remotely monitor and manage your outlets and other devices.
AC and DC PDU Units
PDUs are available in both AC and DC models to match the power requirements at different kinds of sites. In most cases, an AC PDU will be powered with AC power and will distribute power with an alternating current. DC PDUs will sometimes differ in the sense that they all distribute DC power, but the PDU itself may be powered with AC or DC power, depending on the requirements of your site.
From a field tech's point of view, the units would function identically. DC units are built just like their AC counterparts, except for their output current.
DC power distribution units are designed to provide electric current in the direct current format that many rack-mounted devices use.
Rack PDU Definition
Now let's add another layer to our definition by adding the word "rack."
A basic "rack PDU" is a PDU that is designed to be mounted in an industry-standard equipment rack. These server racks are typically either 19 inches or 23 inches in width. Height can vary from PDU to PDU, but most are just one "rack unit" high. This translates to about 1.75 inches.
A rack-mountable PDU is different from other kinds of PDUs that are designed to be wall-mounted or attached to the side of an equipment rack. These other PDUs conserve valuable physical rack space in cramped equipment racks, but they do increase the distance between the power outputs of the PDU and the power inputs of the devices that will receive electricity.
A rack-mounted power distribution unit usually can manage and distribute large amounts of electricity. They typically allow you to connect them to your current monitoring system and can be accessed remotely.
Benefits of Intelligent PDUs
Intelligent power distribution units are an important part of an integrated monitoring system that protects mission-critical equipment. An efficient unit will allow you to monitor and control the power at your individual outlets, switch power on or off, remotely shut down the power during an emergency power outage, and also allocate power efficiently.
Also, keep in mind that PDUs that were designed to meet your specific needs will be able to provide you with customized features to attend your remote sites' requirements.
In a nutshell, the most important advantages PDUs offer include:
You'll know you where your energy is going.
The best PDUs will be able to give you monitoring capabilities as well as power consumption data. This way, your network techs will be able to know where energy is being consumed the most.
You'll have better control over your power.
Your technicians will be able to remotely toggle even individual outlets. This makes it possible to turn off non-essential gear when an outage happens and UPS runtime needs to be maximized. Also, you can remotely restart your equipment after an issue to restore normal operations.
You'll save money on network components.
The most modern PDUs will allow you to daisy-chain network connectivity, so you'll only need a single port and one IP address for multiple PDUs.
Up-to-the-minute information about remote equipment.
Advanced PDUs will have intuitive web interfaces that be accessed by your techs when they need information about remote sites, such as alarms. Not only that, but you'll also get immediate notification about alarms and issues through whichever method you prefer, like email or text messages. This all makes it possible to check the operation of your remote power system in real-time so you can detect and correct problems in a timely manner.

In layman's terms, a rack Power Distribution Unit (PDU) is a device that can be fitted with multiple outlets to effectively control and distribute electricity. The two main types of rack PDUs can be classified as either non-intelligent PDUs or intelligent PDUs. Creating the proper configuration for your data center will require you to first understand the key differences between these two types of rack PDUs.
There Are Two Main Types Of Non-intelligent Rack PDUs.
Basic PDUs: A basic PDU is typically a power strip that accurately distributes the correct voltage and current to multiple outlets within an IT environment. The basic PDU can be used to supply power to IT equipment within racks.
Monitored PDUs: As its name suggests, a monitored PDU visually displays the current electric information. It is important to note that in non-intelligent rack PDU, the display information can only be viewed locally, and lack remote capabilities.
There Are Four Main Types Of Intelligent Rack PDUs.
Metered Input PDUs: This type of intelligent rack PDU displays metered power locally and over a secure network. The metering capability helps managers avoid overloading circuits. It also helps them to more easily calculate the Power Usage Effectiveness (PUE).
Metered Outlet PDUs: The meter power is displayed locally and over a secure network. It is used to accurately determine power usage, as well as the available capacity at the rack level. Finally, outlet-level metering can help managers efficiently identify the power consumption at the device and server level. This identification makes it easier to effectively allocate costs to specific data center customers.
Switched PDUs: This type of intelligent rack PDU has the same features as the Metered Outlet PDU, while simultaneously providing the control needed to power on / off switches to specific outlets. The latter capability increases remote capabilities by allowing authorized users to securely power devices on / off, create power sequencing delays that minimize the risk of inrush currents, reduce the risk of unauthorized access to devices, and reduce the data center's costs and environmental footprint by powering off devices that are not being used.
Switched PDUs with Outlet Metering: This type of intelligent rack PDU successfully combines all of the capabilities of Switched PDUs, Metered Outlet PDUs, and Metered Input PDUs. It is the most robust type of intelligent rack PDU and can be used to help data centers effectively reduce costs and maximize energy efficiencies across devices.
