The Open Rack Power Architecture is comprised of a centralized scalable power shelf and a BBU (Battery Backup Unit) shelf that distributes power over a common bus bar to the payload devices (IT Gear). This spec will define the BBU shelves that fit into the Open Rack. The BBU shelf shall house 6 BBU Modules with 5+1 redundancy to provide the DC ...

bbu架將包含六個bbu模組，具有5+1冗餘能力，為機架內的所有有效載荷提供直流電源。 當交流電源斷電時，BBU架可以在指定的備用時限內持續提供備用電源，功率最高可達電源架的最大額定值。

其中 BBU （Battery Back-up Unit）作为可选部件安装在机柜内，它的作用是类似安装在机柜内部的 UPS，可以在机柜停电时为服务器硬件提供额外的备份时间。 当机房整体配电构架采用混合的OCP机柜+传统机柜时，在有独立的UPS供电的情况下，则可省略BBU。 03. OCP项目的优势. 35℃进风温度，更高的能效. 传统的服务器机柜的配电过程如下图所示，电源经过配电列头柜后到每个服务器电源单元（PSU）中，AC/DC 变换器将220V交流电压变换为380V-410V 的直流电 …

BBU Shelf是一种设计用于提供备用电源的设备，确保服务器和其他关键设备在主电源故障或短期停电时能够继续运行，从而防止数据丢失和系统停机。 BBU Shelf主要由两种模块化组件构成：BBU组件和PMC组件。

2U Power shelf system up to 15 kW capacity with 6pcs BBU modules; High power efficiency (> 97%) for cost-saving operation; Completed full certification of UL9540A: Module, Shelf Level

The BBU shelf will contain six BBU modules with 5+1 redundancy to provide DC power to all payloads within the rack. When an AC power outage occurs, the BBU shelf can provide backup power up to the maximum rating of the power shelf for a specified backup time period.

2024年11月19日 · BBU應用中使用MAX32625 作為層架微控制器(Shelf Microcontroller)，此為一款超低功耗 Arm Cortex-M4 微控制器，在應用中負責多個程式，包括透過Modbus協定與主機通訊、透過Modbus協定與模組通訊、處理模組的定期充電，以及系統控制模式。

Choosing and implementing the proper device for the BBU module and shelf simplifies the overall design, extends the battery lifetime cycle, reduces the long engineering development lead time, and minimizes engineering and production costs.

MWBBES-212-A provides a delivery system for up QTY four (4) 4kW Battery Backup Units (BBU) and a Battery Control Unit (BCU) for deployment in OCP systems and other distributed architecture applications requiring a highly reliable, scalable energy storage solutions.
