The development trend of PDU

PDU (Power Distribution Unit) is the terminal distribution equipment that assigns the output current from UPS to the terminal distribution equipment of each IT device. It is the key equipment to connect the power supply infrastructure with the IT system and the normal operation of all the equipment in the associated machine room. As an important guarantee for the safety of power consumption in the computer room, the stability and safety of the PDU equipment is directly related to the power safety of the IT equipment and even the whole computer room. With the rapid development of cloud computing and Internet of things technology, the construction of data room has also ushered in a new stage of development, and the PDU product has a higher requirement. These requirements promote the following three obvious characteristics in the evolution of PDU products.

The first choice is the security feature. As an important part of the power distribution system, the safety of PDU products is the most important attribute. According to the relevant research organization statistics, 80% of electrical equipment accidents are caused by electrical interface problems. Therefore, as the power interface of computer room equipment, PDU will be one of the most concerned features of customers in the future development. This is the most important reason for the conversion of the data center customers with ordinary sockets to the use of PDU products, because the safety and reliability of the PDU products is much higher than that of the ordinary power sockets.

Because of the special environment in the cabinet, in order to improve the safety of electrical equipment, PDU not only can withstand the total power of the load in the IT room, but also have excellent overload protection mechanism to prevent the potential fire caused by overheating of the circuit because of overload. Many manufacturer's products have extraordinary performance in this respect, such as Emerson Avocent PM PDUs series products. Besides high reliability electrical performance, such as low temperature rise, high load flow, anti misuse, high precision pluggable, installation convenience and so on, it also has socket level, phase level and socket level current metering function. And threshold / alarm function. Before the problem of overload, it can send out a preemptive notice to any situation on the brink of overload, and simplify the task of installing new equipment, thus improving the reliability of the system.
