Dual input PDU

Dual input Power Distribution Units (PDUs) are essential for ensuring power redundancy in data centers and critical IT environments. These devices allow for the connection of two separate power sources to a single unit, thereby enhancing reliability and uptime for connected equipment.
Dual input PDUs have two power cords that connect to separate power sources, such as utility power and a generator or two different utility feeds. The PDU continuously monitors both power sources and automatically switches to the secondary source if the primary source becomes unstable or fails.
When the primary source is restored and stable, the PDU switches back to the primary feed to maintain optimal efficiency. The automatic transfer switch (ATS) functionality ensures seamless transitions between power sources without disrupting connected devices.
Some dual power PDUs also feature local and remote monitoring capabilities, allowing users to track power consumption, detect overloads, and receive notifications in case of power source issues.

Key Features of Dual Input PDUs

Fuente de alimentación redundante

Dual feed PDUs provide N+1 redundancy, which means that if one power source fails, the other can continue to supply power without interruption. This feature is crucial for maintaining uptime in mission-critical applications.

Conmutación automática de transferencia

Many dual input PDUs incorporate Automatic Transfer Switches (ATS) that automatically switch between power sources. This ensures that connected devices remain powered even if one source fails. Some models can handle the switching without interrupting the power supply, which is vital for sensitive equipment.

Eficiencia espacial

Dual feed PDUs often combine two PDUs into a single chassis, saving space in server racks. This design allows for easier management and organization of power distribution while maintaining a clear distinction between primary and secondary feeds

Seguimiento y gestión

Advanced dual source PDUs come with monitoring capabilities that allow users to track power usage, voltage, current, and other metrics through integrated LCD displays or remote monitoring systems. This feature aids in proactive maintenance and troubleshooting.

Compatibilidad con dispositivos de fuente de alimentación única

These PDUs are particularly beneficial for devices that only have a single power supply. By connecting them to a dual input PDU, organizations can ensure that these devices remain operational during power outages or maintenance events.

Customize Dual Input PDU from YOSUN

Voltage and Power Capacity
Confirm the voltage and power requirements of the equipment that will be connected to the PDU.
Ensure the PDU can handle the total power consumption of all connected devices without exceeding its maximum capacity.
Configuración de salida
Determine the number and type of outlets needed based on the connected equipment (e.g. C13, C19, NEMA).
Consider having more outlets than currently needed to allow for future growth.
Match the outlet types and quantities on both PDU inputs for redundancy.
Redundancia y conmutación por error
Ensure the PDU supports automatic failover between the two inputs in case one power source fails.
Configure the PDU to link redundant inputs of connected devices together for easy rebooting from a single interface.
Instalación física
Choose between horizontal (rack-mounted) or vertical 0U PDU form factors based on available rack space.
Opt for slim chassis designs to maximize outlet density.
Use different colors for the two PDU inputs to easily distinguish between the primary and secondary power sources.
Monitoring and Control
Decide if you need individual outlet switching, remote power monitoring, or other advanced features.
Look for PDUs with digital metering to monitor power consumption and prevent overloads.

Benefits of Automatic Switching in Dual-Feed PDUs

1. Minimized Downtime
Seamless Transition: Automatic switching ensures that if the primary power source fails, the PDU can instantly switch to the secondary power feed without manual intervention. This rapid response minimizes downtime, which is crucial for maintaining continuous operation in data centers.
Reliability During Outages: In environments where even brief power interruptions can lead to significant operational disruptions or financial losses, automatic switching provides a reliable backup solution that keeps systems running smoothly.
2. Enhanced Equipment Protection
Avoiding Power Fluctuations: Sudden power loss can damage sensitive equipment. Automatic switching protects against these fluctuations by ensuring a stable power supply is maintained, thereby safeguarding critical IT infrastructure.
Continuous Power Supply: The automatic transfer mechanism ensures that equipment remains powered even during maintenance or unexpected failures of the primary source, reducing the risk of data loss or corruption.
3. Operational Efficiency
Reduced Human Error: Automating the switching process eliminates the potential for human error associated with manual switching. This is especially important in high-pressure environments where quick decisions are required to maintain uptime.
Simplified Management: With integrated monitoring capabilities, users can oversee both power feeds from a single interface, streamlining management tasks and allowing for quicker responses to any issues that arise.
4. Cost-Effectiveness
Lower Operational Costs: By ensuring continuous operation and protecting equipment, automatic switching can help reduce costs associated with downtime and equipment replacement. This leads to a more cost-effective power management solution overall.
Space Savings: Dual-feed PDUs with automatic switching are often designed to occupy less space than traditional setups requiring multiple units, allowing for more efficient use of valuable rack space in data centers.
