Power Distribution Units


A PDU (power distribution unit) is a power strip, which is installed most of all in 19-inch server cabinets, either horizontally or vertically. These cabinets are often server racks used in data centers and server rooms. A PDU distributes the power to different consumers, such as servers and switches. Different types of device connections are possible: The most common ones are IEC C13, IEC C19 and safety sockets.

  

            

      

 

There are basically two types of PDUs:

Passive PDU: It's a simple power strip that just distributes power.

Active PDU: In addition to the power distribution, an active PDU disposes of additional functions. It can be monitored and controlled via a data interface. Thus, an active PDU communicates via its LAN interface for example by TCP/IP as well as protocols such as SNMP, Modbus and HTTP/HTTPS. In this way, the PDU allows for remote controlling and integration into monitoring software. Furthermore, sensors can often be connected so that e.g. temperature and humidity of the environment can be measured. By configuring threshold values, the active PDU can be enhanced by alarm functionality: When one of the stored thresholds is exceeded, the PDU sends an e-mail immediately.

Within the active PDUs, a distinction can be made between switched and metered PDUs. These PDUs are also often referred to as smart power strips.

                                                                              


An overview of the active PDUs available at GUDE is provided in the following. Further information can be found on the detail pages of the respective PDU. A comparative overview of the features of the smart power distribution strips can be found in this comparison chart.
