Different types of PDUs – which one best suits your needs?

Posted in Computers

When it comes to computers and networks, there are several essential elements that a user must have and one very good example is a Power Distribution Unit (PDU). Over time, technology has advanced so much that the PDUs available on the market nowadays differ not only from their previous versions launched sometime before, but also from one another. Before you purchase an APC Switched Rack PDU, it is best that you know more on the different types of PDUs available.

 

Basic PDUs

The basic PDU is mostly used as a cost-effective, dependable and space-saving means to deliver power to server rooms, wiring closets and various equipment racks from UPSs systems, utility wall outlets or generators. The basic PDU adds several more outlets to the UPS than they were initially provided, thus converting one high-amperage UPS outlet to several other low-amperage PDU outlets.

Metered PDUs

Metered PDUs are used to monitor load levels so that there are no unfortunate events such as overloads that may compromise the well-function of the network. It comes with a built-in digital meter which provides rack-mount, reliable, single or three-phase, multi-outlet, power distribution coming out of any protected UPS, input power source or generator.

Monitored PDUs

Compared to metered PDUs, monitored ones go even one step further when it comes to monitoring single or three-phase voltage, load levels and frequency in real-time using the built-in network connection. There is a visual meter that provides information on the output current consumption so that overloads are avoided.

Switched PDUs

Switched PDUs are extremely useful because they allow the user to remotely connect, disconnect and monitor any data center loads. Due to the built-in digital current meter and to control individual outlets which can be used to reboot locked equipment, these PDUs make a very good investment. In case there are some PDU outlets that you do not use, know that you can have them locked off in order to prevent any connection of unauthorized hardware. You are constantly provided with details related to amperage, voltage, and kilowatt output values per phase. All you have to do to use this PDU is to connect it to an Ethernet jack.

Automatic transfer switch PDUs

Experts in the field recommend that instead of purchasing new IT equipment that comes with redundant power supplies, users can opt for buying an ATS (Automatic Transfer Switch) PDU instead. They are either switched or metered PDUs which are designed to facilitate the continuous function of any device that is connected to a PDU via an auto-transfer-switch. This switch allows the device to transfer to a secondary source of power the next moment the primary source encounters any power difficulties.

All things considered, these are the main types of PDUs that can be found on the market. It is essential you have a clear idea on what each of them is used for so that when you make a decision, you opt for the Power Distribution Unit type that best suits your needs and budget. Keep in mind that you have to resort to a professional provider that can guarantee you top quality products and services.
