The primary components of a dual feed PDU include:

  • Dual power inputs: Ils fournissent N+1 redundancy, ensuring continuous power delivery.
  • Automatic transfer switching: This feature enables seamless switching between power sources, reducing disruptions.
  • Failover capabilities: These protect connected devices by maintaining power during failures.

By using a dual feed PDU, you can ensure reliable power distribution for your IT equipment while reducing the risk of downtime.

How Dual Feed PDUs Work

Power Source Redundancy

Dual feed PDUs connect to two separate power sources, such as utility power and a backup generator. This setup enhances reliability by creating a redundant power supply. If one source experiences a failure, the second source ensures continuous operation. This redundancy is crucial for protecting your equipment and maintaining uninterrupted service.

Automatic Switching Mechanism

Le commutateur de transfert automatique (ATS) is a key feature of dual feed PDUs. It enables instant switching from the primary power source to the secondary source without manual intervention. This seamless transition ensures that your connected devices remain operational during power source failures. The ATS design reduces downtime risk and enhances system reliability.

Applications in Critical Power Systems

Dual feed PDUs play a vital role in critical power systems. They are widely used in:

  • Centres de données: Ensuring continuous power for servers and networking equipment.
  • Télécommunications: Maintaining reliable power for communication infrastructure.
  • Industrial facilities: Supporting high-demand machinery and equipment.
  • Healthcare: Powering life-saving medical devices and systems.

These units are indispensable in environments where power interruptions can lead to significant losses or safety risks. By integrating a dual feed PDU into your system, you can safeguard your operations and maintain consistent performance.

Key Technical Specifications of Dual Feed PDUs

Input Power Capacity

Voltage and Current Ratings

When selecting a dual feed PDU, understanding its voltage and current ratings is essential. These ratings determine the unit’s compatibility with your power system and its ability to handle the required load. Below is a table summarizing standard voltage and current ratings for dual feed PDUs:

Voltage RatingCurrent Capacity
120 Volts15 Amp, 20 Amp, 30 Amp
208 Volts15 Amp, 20 Amp, 30 Amp
240 Volts15 Amp, 20 Amp, 30 Amp
120/208 Volts15 Amp, 20 Amp, 30 Amp
Up to 480 VacCustom capacities available

These options provide flexibility, allowing you to choose a PDU that meets your specific power requirements.

Supported Power Sources

Dual feed PDUs connect to two independent power sources, such as utility power and a backup generator. This setup ensures redundancy, enabling continuous operation even during power failures. You can also integrate them with renewable energy sources, like solar or wind power, to support sustainable operations.

Output Power Distribution

Outlet Types and Configurations

Dual feed PDUs offer various outlet types, including IEC C13, C19, and NEMA configurations. These outlets accommodate a wide range of devices, from servers to networking equipment. Units often feature locking outlets to prevent accidental disconnections, ensuring a secure power connection.

Load Balancing Features

Load balancing is a critical feature in dual feed PDUs. It distributes the electrical load evenly across the available power sources, improving efficiency and reducing the risk of overloading.

Having two (or four) rack-level PDUs available for a server means that the computing load is shared – when two are used, each PDU handles about 50% of the load. When one power feed fails, the remaining supply supports the entire load. For this reason, despite what it may seem, a PDU becomes overloaded at any level above 50% power.

This feature ensures optimal performance and protects your equipment from power-related issues.

Switching Mechanisms

Automatic Transfer Switch (ATS)

Automatic transfer switches are a key component of dual feed PDUs. They provide several advantages:

  • Redondance: Ensures continuous power supply by connecting to two separate power sources.
  • Réduction des temps d'arrêt: Swift transfer between power sources keeps systems running without interruption.
  • Protection renforcée de l'équipement: Prevents damage from unstable power conditions.
  • Facilité d'utilisation: Automated process requires no manual intervention.
  • Rapport coût-efficacité: Reduces risk of downtime and equipment failure, saving on repair costs.

The ATS continuously monitors both power sources. If the primary source fails, it instantly transfers the load to the secondary source. This seamless transition ensures uninterrupted power delivery and protects sensitive equipment.

Manual Switching Options

Some dual feed PDUs also offer manual switching mechanisms. These allow you to control the power source selection manually, providing flexibility in specific scenarios. While less automated, manual switching can be useful in environments where you need precise control over power distribution.

Fonctionnalités de surveillance et de gestion

Capacités de surveillance à distance

Remote monitoring capabilities in a dual feed PDU allow you to track and manage power usage from anywhere. These features provide real-time insights into energy consumption, environmental conditions, and equipment performance. The table below highlights the key benefits of remote monitoring:

How to Choose the Right Dual Feed PDU

Évaluer les besoins en énergie

Current and Future Load Demands

When choosing a dual feed PDU, you need to evaluate your current and future power needs. Start by calculating the total power consumption of all connected devices. This ensures the PDU can handle the load without overloading. Consider whether your setup requires single-phase or three-phase power. High-demand environments, like data centers, often benefit from three-phase power for better efficiency.

You should also determine the number and type of sockets required. For example, servers and networking equipment may need IEC C13 or C19 outlets. If you plan to expand your setup, choose a PDU with extra capacity to accommodate future growth. Intelligent features, such as remote monitoring and switching, can further enhance efficiency and reliability. Lastly, assess the PDU’s reliability by checking its mean time between failure (MTBF) rating.

Compatibilité avec les infrastructures existantes

Ensure the PDU integrates seamlessly with your current infrastructure. Check the voltage and current ratings to match your power system. Verify that the PDU’s form factor fits your rack space. For example, a vertical (0U) PDU is ideal for maximizing rack space, while horizontal units suit smaller setups. Compatibility ensures smooth installation and operation without requiring major adjustments.

Evaluating Technical Features

Monitoring and Management Needs

Modern dual feed PDUs offer advanced monitoring and management features. These include real-time tracking of power usage, environmental conditions, and equipment performance. Remote management capabilities allow you to control the PDU from anywhere, improving efficiency and response times.
