Why Choose the APC AP9559?
The AP9559 is an excellent choice for IT environments that need dependable power distribution without the complexity or cost of advanced PDUs. Its key advantages include:
- Simplicity and Reliability: As a basic PDU, it focuses on delivering consistent power to multiple devices, making it ideal for environments where monitoring or remote control is unnecessary.
- Cost Efficiency: Priced lower than metered or switched PDUs (typically £150–£300), the AP9559 saves money during installation by using a single branch whip and standard connections.
- Versatility: The combination of C13 and C19 outlets supports a wide range of equipment, from low-power networking devices to high-power servers.
- Space-Saving Design: The 1U form factor maximizes rack space, leaving room for other critical equipment.
- Global Compatibility: Its support for 208V and 230V inputs and multiple output voltages makes it suitable for data centers worldwide.
Compared to switched PDUs like the APC AP7922B, the AP9559 lacks remote management and monitoring features but offers a budget-friendly alternative for applications where basic power distribution is sufficient.
Ideal Use Cases
The AP9559 is well-suited for:
- Small to Medium Server Rooms: Powers servers, routers, and switches in environments with limited rack space.
- Network Closets: Distributes power to networking equipment like patch panels and firewalls.
- Edge Computing Sites: Provides reliable power for distributed IT infrastructure in remote or branch locations.
- Test Labs: Supports temporary or experimental setups requiring flexible power distribution.
- Budget-Conscious Deployments: Ideal for organizations prioritizing affordability without sacrificing reliability.
Installation and Setup
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 report minor issues with bracket fitment.
- 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.
Customer Feedback
Users appreciate the AP9559 for its simplicity and reliability but note some limitations:
- Positive: “This PDU is plug-and-play, perfect for our small server room. The C19 outlets are great for our high-power servers.” – IT Administrator
- Positive: “Good value for the price. Installation was quick, and it’s been running flawlessly for over a year.” – Network Technician
- Critical: “The rack-mounting brackets are a bit flimsy, and the screw holes didn’t align perfectly. Siemens or HP PDUs have better build quality for mounting.” – Amazon Review
- Critical: “No monitoring or remote control, so you’ll need a higher-end model if you want those features.” – Data Center Manager
Overall, the AP9559 is praised for its affordability and performance but may not suit environments requiring robust mounting or advanced functionality.
Maintenance Tips
- Inspect Connections: Regularly check input and output connections for security and wear to ensure reliable performance.
- Clean the Unit: Dust the PDU periodically to prevent overheating and maintain efficiency.
- Monitor Load: Avoid exceeding the 16A (3680VA at 230V) capacity to prevent circuit overloads.
- Use Cord Retention: Install the optional AP9569 bracket to secure power cords and reduce disconnection risks.
- Recycle Responsibly: Utilize Schneider Electric’s take-back program for eco-friendly disposal at the end of the PDU’s lifecycle.
Comparison with Similar Products
Compared to other PDUs, the AP9559 offers:
- Simplicity vs. Advanced PDUs: Lacks the remote control of switched PDUs (e.g., APC AP7922B) or current monitoring of metered PDUs (e.g., APC EPDU1016M) but is more affordable.
- Outlet Variety: The mix of 10 C13 and 2 C19 outlets provides more flexibility than PDUs with only C13 outlets (e.g., CyberPower PDU20BHVIEC12R).
- Compact Design: Its 1U form factor is more space-efficient than 2U PDUs like the AP7922B, though it supports a lower power capacity (16A vs. 32A).
- Build Quality: Some competitors (e.g., Siemens, HP) offer sturdier mounting brackets, but the AP9559’s price-to-performance ratio is competitive.
For users needing monitoring or remote control, the APC EPDU1016M (metered, 1U, 16A) or AP8858 (metered, ZeroU) may be better alternatives, though they are pricier.
