Key Features of the APC AP9559
1. Versatile Outlet Configuration
The AP9559 offers 12 total outlets: 10 IEC C13 outlets for standard IT equipment (e.g., servers, switches, routers) and 2 IEC C19 outlets for high-power devices (e.g., blade servers, storage arrays). This combination provides flexibility to support diverse equipment needs within a single PDU.
2. Wide Voltage Compatibility
With support for input voltages of 200V, 208V, or 230V and output voltages of 120V, 208V, or 230V, the AP9559 adapts to varying power requirements, making it suitable for global data center environments. Its IEC-320 C20 input connector ensures compatibility with standard power sources.
3. Compact 1U Design
The 1U form factor maximizes rack space, leaving room for other critical equipment in space-constrained server rooms or cabinets. Its lightweight design (980 g) simplifies installation and handling.
4. Single Branch Whip Installation
The AP9559 uses a single branch whip to power multiple devices, reducing cabling complexity and installation costs. The 8.2-foot (2.5-meter) input cord provides ample length for flexible placement within racks.
5. Toolless and Horizontal Mounting Options
The PDU includes rack-mounting brackets for easy installation in standard 19-inch racks. While some users have noted minor issues with bracket fitment, the design supports both horizontal and toolless mounting options for versatility.
6. Reliable Build Quality
Manufactured by Schneider Electric, the AP9559 is built for durability and complies with international safety and environmental standards, ensuring reliable performance in critical IT environments.
Benefits of the APC AP9559
Cost Efficiency
Priced typically between £150–£300, the AP9559 is a budget-friendly alternative to switched or metered PDUs, offering reliable power distribution without the added cost of advanced features. Its single branch whip design saves money during installation by reducing cabling needs.
Simplicity and Reliability
The basic PDU design focuses on delivering power without the complexity of monitoring or remote control, making it ideal for environments where straightforward power distribution is sufficient. Its robust construction ensures dependable operation for critical IT equipment.
Space Optimization
The compact 1U design maximizes rack space, making it suitable for small to medium-sized server rooms or network closets with limited rack capacity.
Global Compatibility
The AP9559’s support for multiple input and output voltages (208V and 230V) and its IEC-standard connectors make it a versatile choice for data centers and IT facilities worldwide.
Applications of the APC AP9559
The APC AP9559 is well-suited for:
- Small to Medium Server Rooms: Powers servers, routers, and switches in environments with limited rack space.
- Network Closets: Provides reliable power distribution for networking equipment in branch offices or small IT setups.
- Colocation Facilities: Supports multi-tenant environments with its flexible outlet configuration.
- Enterprise IT: Delivers power to critical equipment in cost-sensitive deployments where advanced monitoring is not required.
Installation Process
Installing the AP9559 is straightforward and requires minimal tools:
- Mount the PDU: Secure the PDU in a 1U rack space using the included rack-mounting brackets. Ensure proper alignment, as some users have reported minor fitment issues with the brackets.
- Connect the Input: Plug the IEC-320 C20 input cord into a compatible 16A, 208V or 230V power source.
- Connect Devices: Attach up to 10 devices to the IEC C13 outlets and up to 2 high-power devices to the IEC C19 outlets.
- Secure Cords: Optionally use the APC Cord Retention Bracket (AP9569) to prevent accidental disconnections.
- Verify Operation: Ensure all connected devices receive power and check for proper grounding.
The package includes a User Guide, Rack-Mounting Brackets, and Safety Guide for easy setup. For detailed instructions, refer to the AP9559 Product Datasheet or Schneider Electric’s support resources.
Comparison with Switched PDUs
Compared to switched PDUs like the APC AP7922B, the AP9559 lacks remote management and monitoring features, such as outlet control or current monitoring displays. However, its lower price point and simpler design make it an excellent choice for applications where basic power distribution is sufficient. For environments requiring advanced control, a switched PDU like the AP7922B may be more appropriate.
Considerations
While the AP9559 is praised for its reliability and affordability, some users have noted minor issues with the rack-mounting brackets, such as imprecise fitment or fragile design. Ensuring proper alignment during installation can mitigate these concerns. Additionally, as a basic PDU, it does not offer monitoring or remote control, so it may not suit environments requiring detailed power management.
Conclusion
The APC AP9559 Rack PDU Basic 1U 16A 208&230V (10)C13 & (2)C19 is a reliable and cost-effective solution for distributing power to IT equipment in small to medium-sized server rooms, network closets, and colocation facilities.
