Power Distribution Unit

A power distribution unit is a device that enables the sufficient flow of electricity in an IT network environment. It draws power from a source such as a universal power supply (UPS) or a wall outlet and acts as a source for network devices like switches, servers and the like. In appearance, it is similar to a household power strip. However, that is where the similarity ends. A PDU can do a lot more than just surge protection. From its form factor to advanced capabilities, manufacturers design PDUs for particular applications. A basic PDU will act as a surge protector and a noise filter, but a more advanced one can help you run an efficient network on your fingertips.

Save Valuable Rack Space

Although all PDUs are efficient in what they do, the design of rack power distribution units pushes the bar even further. With a minimal footprint, you can install these PDUs on the rack with provided hardware. The locations of the receptacles minimize the power line distance. You can get PDU surge protection in a variety of NEMA connector types. The locking connector types provide an additional feature for easier cable management. The configuration of traditional household power strips is different. Depending on your application, you can pick a PDU with the desired number of outlets.

Stay in the Know With Real-Time Monitoring

Metered power distribution units have a built-in display that shows the usage data. This real-time information can be as simple as the load or more broken down data for long term analysis. Some PDUs come with a network connection and can transmit this data for remote monitoring. A slight fluctuation in usage can change the balance of the load. With remote monitoring, you are aware of the current situation. This way, the issue of overloading can be easily avoided, and in some cases, you can make an informed decision about your existing network. For example, adding redundant power supplies. Often these PDUs are more rugged and come with shielded switches or no switches at all. This prevents any accidental shutoff of the network.

Manage the PDU Remotely

Switched rack PDUs add a level of convenience. Not only can you monitor your equipment’s performance from a distance, but you can also control them. The switched PDUs are capable of controlling each outlet individually. You can turn off the connection to redundant server power supplies when there is a strain on the PDU. If equipped with the necessary software, you can also automate this based on a preset schedule. If your application requires 100 percent up-time, you can choose a hot-swappable PDU. These PDUs can have dual power supplies. The secondary power supply acts as a redundant source and makes room for repairs and maintenance. These switched rack PDUs have a hot-swap switch that can change the source without losing power. Once you remove the UPS as a primary source, you can change its battery or tackle any maintenance issue it might have.
