Power Distribution Units
Data centers, networking environments, and any place that needs electricity distributed properly and efficiently to multiple devices will have power distribution units to distribute network power. These come in a very wide range of types: some that are very basic and just have a few extra outlets, to a variety of increasingly more complex control features, for example, to allow global system administrators to pay more attention to and control power management where it mostly counts—like in a data center. Basic PDUs provide standard electrical outlets without monitoring or remote access capabilities, while more advanced units offer real-time monitoring and remote access capabilities.
Created for installation in network racks and cabinets, PDUs often possess multiple sockets to satisfy the network power necessities of rack-mounted equipment like servers, switches, routers, and other network appliances. This setup not only tends to simplify the process of power administration but also tends to enhance safety around and reliability of electrical supply to equipment and, therefore, to the network by incorporating such features as surge protection, circuit breakers, and filtering to protect the electrical supply from wobbles and spikes and to keep the power supply from creating electrical interference.

More Information about Power Distribution Units
Intelligent power distribution units (PDUs) do far more than just hold the plug: They include intelligent features that enable remote administration and management of individual outlets or groups of them. This can be very handy indeed because it allows IT administrators to reboot unresponsive servers, manage power usage, or even automate power uptime for equipment maintenance—all from the comfort of the IT work area. In addition, some PDUs—with the “environmental awareness” replete with temperature, humidity, and airflow sensors—also offer an almost total view of what’s going on inside the rack.
Differences between Power Supplies, Inverters, Uninterruptible Power Supply, and Transformers
Power Supplies with Power Metering
A power supply converts one type of power to another. The most common example is a power supply that takes AC voltage and converts it to DC voltage. While it is very common to use power supplies in industrial applications, one very common place to see a power supply used is for the devices such as: smartphones, laptops or tablets. Most devices come with a power cord that has a bulky block on the end of it. This block is where the power supply is located. Most devices do not use AC power, which is the type of power being supplied to homes. They use some form or DC power. The power supply changes the AC voltage to the correct DC voltage for the device.
Inverters
Inverters work in a similar way to power supplies, with one major difference, instead of converting AC power to DC power, the inverter does the opposite. It converts DC power to AC power. DC power is created by devices such as solar panels or batteries, but most homes require AC power. To convert the DC power that is generated by the solar panels, an inverter is used.
Transformers
Transformers convert one type of AC power to a different type of AC power. For example, homes commonly use 120 VAC and automatic sprinkling systems have valves that require 24 VAC. A transformer converts 120 VAC to 24 VAC so the sprinkler valves can operate properly. Transformers come in many different shapes and sizes. and can convert AC power up or down.
