Function of Intelligent Power Distribution Cabinet Controller
Abstract: The intelligent control device can be used for 3~35kV indoor high-voltage switch cabinets, suitable for various switch cabinets such as central cabinets, handcart cabinets, fixed cabinets, ring network cabinets, etc., with a primary circuit simulation diagram. Smart PDU (Power Distribution Unit) is a power management device used in data centers and computer rooms. It not only supplies power to IT equipment in data centers, distributes power to various servers and network devices, but also provides remote monitoring, management, and control of power. An Intelligent Power Distribution Unit (iPDU), also known as a Smart PDU or Intelligent PDU, is a critical component in modern data center infrastructure. While both can provide reliable power distribution to critical IT equipment within a rack or cabinet, intelligent PDUs offer several smart features to help data center managers understand their power. This paper will deeply discuss the structure, function, application and future development trend of power distribution cabinet, in order to provide readers with a comprehensive and in-depth understanding. Intelligent PDUs, or iPDUs, enable smarter IT infrastructure for increased uptime, increased efficiency, improved capacity. -
