FS Introduces Intelligent Dual Feed PDU Series to Optimize Power Management

Posted on Jul 9, 2024 by

In modern data centers, Power Distribution Units (PDUs) are crucial for ensuring continuous operation. The intelligent single-phase dual-feed PDU (Power Distribution Unit) is a crucial component in the management of modern data centers and IT equipment. Its primary function is to provide a stable power supply to devices while enhancing the operational efficiency and reliability of data centers through smart monitoring and management features.

Why Dual-Feed PDUs Are Ideal for Data Centers

Dual-feed PDUs are optimal for data centers due to several key advantages. They provide redundant power protection through dual power input paths, ensuring continuous power supply and minimizing downtime. Moreover, to simplify power operations within racks and minimize human error, some data center managers use color-coded dual-feed PDUs to differentiate between A and B power feeds. This enhances reliability and stability, reducing the risk of single points of failure crucial for 24/7 uninterrupted operations. Additionally, dual-feed PDUs can adapt to changing equipment and power demands, offering flexible expansion capabilities. They also support unified configuration and management through integrated software, simplifying equipment expansion and improving management efficiency.

FS Intelligent Single-Phase Dual Feed PDU Series Products

FS offers a range of intelligent single-phase dual feed PDUs that cater to varying needs for power distribution in data centers and IT infrastructures. These advanced PDUs integrate features such as redundant power supply, automatic switching, and comprehensive monitoring capabilities, ensuring enhanced reliability and operational efficiency in data centers and IT environments.

FS provides four types of dual feed PDUs, categorized by functionality into the W PDU Series, Wi PDU Series, WS PDU Series, and WSi PDU Series.

Through the parameter table below, you can learn about the specific functions of the four types of PDUs in detail. This information will help you fully understand the unique features of each PDU, allowing you to choose the product that best suits your needs.

FS Dual Feed PDU Series

Based on the introduction above, it is clear that the newly introduced PDUs are designed to cater to the diverse needs of different data centers and are categorized into two main types: Monitoring PDUs and Switched PDUs. Each PDU boasts unique functional features, as illustrated in the parameter table below, which highlights the primary functional differences between them.

Types Features Application Scenarios
W Series- Strip Monitored Circuit and Temperature Humidity Monitoring Environments requiring overall power monitoring
Wi Series - Socket Monitored Circuit Monitoring and Outlet Monitoring Precision management environments requiring power monitoring for each socket
WS Series - Socket Switched Strip Monitored Circuit Monitoring and Outlet Switching Environments needing remote control of each socket and overall power usage monitoring
WSi Series - Socket Switched & Socket Monitored Circuit Monitoring and Outlet Level Measurement Over IP High-density management environments requiring power monitoring and switch control for each socket

Superior Advantages of FS Dual-Feed PDUs

Save Valuable Rack Space

Traditionally, data center racks typically accommodate two PDUs, installed at the rear left and right positions. Dual feed PDUs are designed to integrate both PDUs into a single chassis, requiring installation on only one side. This design simplifies the PDU setup process and saves space. Users can also distinguish between primary and secondary PDUs through a layout marked in red and blue, providing a more convenient user experience.

Remote Monitoring and Management

PDU remote management helps reduce labor costs, thereby improving uptime and productivity. It also facilitates capacity planning and enhances the overall efficiency of data centers. Intelligent PDUs offer three remote management options for users to choose from:

  • 1. GUI (Graphical User Interface): Provides an intuitive graphical interface for easy monitoring and management of PDUs, simplifying operational processes.

  • 2. DCIM via SNMP or API: Integrates SNMP protocol or Application Programming Interface (API) into DCIM systems for comprehensive monitoring and management of PDUs and other critical devices, supporting automation and intelligent management of data center infrastructure.

  • 3. IPM-04: Offers free PDU management software supporting centralized monitoring, data analysis, alert notifications, and remote access control, helping users optimize power resource efficiency and enhance operational efficiency.

Ultra High-Density PDU Management

Dual feed PDUs integrate efficient hardware connectivity with software-based remote management for high-density PDU control. Using a patented IP dongle, only 1 IP address is needed to access up to 32 PDUs within a single cascade group. Enhance operational efficiency and simplify network management for your power systems, while achieving cost savings through reduced IP address usage and optimized monitoring capabilities across multiple PDUs.

Optimize Cable Management

Today, separating power and data cables within racks has become a standard practice in cable management for two main reasons:

  • 1. Minimizes data transmission instability and reduces electromagnetic interference.

  • 2. Clearly distinguishes between power and data cables, enhancing overall organization and efficiency within the rack.

Intelligent dual feed PDUs facilitate this separation effectively by employing a space-saving dual feed design and a color-coded red-blue layout, further optimizing space efficiency and rack organization.

Enhancing Redundant Power Systems with Intelligent Dual Feed PDUs

Pain Points

  • 1. Business continuity is essential, but manually monitoring equipment, power consumption and environmental parameters is cumbersome and prone to errors. Unexpected downtime of critical equipment can trigger a series of cascading losses.

  • 2. Configuring each PDU individually is difficult when expanding data center equipment, resulting in low IP utilization. Monitoring and managing multiple devices in data centers or remote facilities leads to low management efficiency and poor user experience.

  • 3. With complex data center cabling, it is challenging to clearly distinguish between primary and redundant power feeds of PDUs during power management and cabling tasks.

Redundant Power Solution

To meet customer demands for business continuity, we offer a redundant power solution. Dual-feed WSi Series PDUs connect to UPS systems via distribution cabinets, ensuring dual power redundancy. In case of a power path failure, the PDU switches automatically to backup power, ensuring continuous operation of critical equipment.

To streamline power management in customer data centers, we cascade multiple PDUs via Cat 5e/Cat 6 cables. Customers can centrally monitor and control all cascaded PDUs through a single IP address, overseeing power usage, equipment status, and distribution. This capability enables quick issue resolution, significantly enhancing operational efficiency and responsiveness in the data center.

Additionally, the PDU is paired with corresponding color-coded power cables (such as red and blue), increasing visual distinguishability, and helping users easily differentiate between PDU A and PDU B for precise power and wiring management within the cabinet.


In summary, FS's intelligent single-phase dual feed PDU series integrates redundant power, automatic switching, and local and remote monitoring capabilities, providing customers with a comprehensive power management solution. As a key component of data center power redundancy solutions, intelligent dual feed PDUs not only offer a highly reliable power supply but also enhance operational efficiency and cost-effectiveness through intelligent management features.
