PDU (Power Distribution Unit) is a type of power distribution equipment mainly used in data centers, server rooms, network cabinets and other places to convert power input into multiple output sockets, providing power supply and management functions for various devices. PDU typically has multiple sockets, circuit breakers, overload protection, and energy monitoring features, which can effectively manage and control power distribution, improve the reliability and efficiency of power supply.
1. What is PDU
PDU (Power Distribution Unit) is a device specifically designed for power distribution and management. It can distribute electrical energy from the power input to multiple output sockets to supply various devices. PDU is usually installed in computer rooms, data centers, or network cabinets to meet the power supply needs of devices by providing multiple power sockets and equipping power management modules with different functions.
2. Function of PDU
PDU has multiple functions to meet power distribution and management tasks in different environments and needs. Here are several common PDU functions:
2.1 Power Distribution
One of the main functions of PDU is to distribute power. It receives electrical energy from the power input and transmits it to various devices through multiple output sockets. According to the needs, PDU can provide different types of sockets, such as regular sockets, IECC13/C14 sockets, or international sockets, to adapt to the power interfaces of various devices.
2.2 Overload protection
PDU usually has built-in overload protection function, which can protect devices connected to its output socket. When the load on a certain socket exceeds the set current threshold, the PDU will automatically disconnect the power supply to that socket to avoid overloading and damaging equipment or causing safety accidents. This overload protection mechanism can effectively protect the security of equipment and data.
2.3 Remote Monitoring and Management
Modern PDUs are usually equipped with remote monitoring and management functions, which can be remotely monitored and controlled through network connections. Administrators can monitor the power usage, device status, and energy consumption of PDUs in real-time through a web interface or specialized software. At the same time, remote control functions can be used to operate power switches, load adjustments, and alarm settings on PDUs, improving the convenience and efficiency of power management.
2.4 Energy Monitoring
PDU generally has energy monitoring function, which can measure and record real-time parameters such as power, voltage, current, power factor, and energy consumption of PDU input and output. These data can help administrators understand electricity usage, identify issues of energy waste and load imbalance, and make corresponding optimizations and adjustments to improve energy efficiency and reduce electricity costs.
