Continue to read this article.

What Is PDU

A PDU is a device fitted with multiple outlets. A PDU delivers AC power from power source to severs. PDU can be installed into a big cabinet with a power cord to transmit electric power to the computers and networking equipment located within a data center. Power cord can power a network device or connect to the PDU and computer in a data rack or network wiring closet. And C13 power cord is the best choice for PDU. In general, PDU is developing all the time. In the beginning, PDU is a simply and cheap rack mount power strip and then become larger floor mount PDUs with multiple functions.
