PDU（Power Distribution Unit），是将来自 UPS 的输出电流分配到各个IT设备的末端 配电设备 ，是连接供电等基础设施与 IT系统 、关联机房内所有设备正常运转的 关键设备 。作为机房用电安全的重要保障，PDU设备的稳定与安全直接关系到IT设备乃至整个机房的用电安全。

What is a power distribution unit (PDU)? A power distribution unit (PDU) is a device for controlling electrical power in a data center. The most basic PDUs are large power strips without surge protection. They are designed to provide standard electrical outlets for data center equipment and have no monitoring or remote access capabilities.

PDU (Power Distribution Unit)高压配电单元，功能是负责新能源车高压系统中的电源分配与管理，为整车提供充放电控制、高压部件上电控制、电路过载短路保护、高压采样、低压控制等功能，保护和监控高压系统的运行。 PDU也能够集成BMS主控、充电OBC模块、DCDC模块、PTC控制模块等功能，与传统PDU相比多了整车功能模块，功能上更加集成化，结构上更复杂，具有水冷或是风冷等散热结构。 PDU配置灵活，可以根据客户要求进行定制开发，能够满足不同客户 …

In telecommunications, a protocol data unit (PDU) is a single unit of information transmitted among peer entities of a computer network. It is composed of protocol-specific control information and user data .

在机房及通信硬件领域中常见的PDU，指的是机柜电源插座，是英文"Power Distribution Unit"的缩写，即电源分配单元。 通过工业标准的PDU可使网络产品的电源安全提高，满足了重要设备电源输入的要求。

A power distribution unit (PDU) is a device fitted with multiple outputs designed to distribute electric power, especially to racks of computers and networking equipment located within a data center. [1]

PDU （Power Distribution Unit）即 电源分配单元 ，是一种机房的专用电源分配设备。 PDU的应用场景广泛，特别是在 数据中心 、 服务器机房 、 网络中心 等需要精细电力管理的场合。

The rack power distribution unit (PDU) is a foundational building block of the modern data center, transforming high capacity raw power feeds to lower capacity outlets for IT equipment.

2024年11月21日 · A PDU (Power Distribution Unit) distributes electricity to connected devices, while a UPS (Uninterruptible Power Supply) provides backup power during outages. Together, they work to ensure consistent and reliable power delivery in a data center.

2024年12月31日 · A Power Distribution Unit (PDU) is essential for efficiently distributing power to multiple IT devices, ensuring reliable operation in data centers and server rooms. Unlike basic power strips, PDUs are designed to handle higher electrical loads and prevent issues like power surges and circuit overloads.
