Designed for simplicity and efficiency, this basic PDU is a go-to choice for server rooms, data centers, and small IT setups needing reliable power without the complexity of advanced features. In this blog, we’ll explore what the AP9559 offers, its key features, benefits, and why it’s a solid pick for your rack power needs.
What is the APC AP9559 Rack PDU?
The APC AP9559 is a 1U (one rack unit) basic rack PDU designed to distribute power to multiple devices in a compact, rack-mounted form factor. Rated at 16A and compatible with both 208V and 230V input voltages, it provides 12 total outlets: 10 IEC C13 and 2 IEC C19 connectors. This configuration supports a variety of IT equipment, from servers and networking gear (C13) to higher-power devices like storage systems (C19). As a “basic” PDU, it focuses on delivering power without the added bells and whistles of switched or metered models, making it an affordable, no-frills solution for environments where remote control or detailed monitoring isn’t required.
With its IEC-320 C20 input and a 3.05-meter cord, the AP9559 is built for easy integration into standard 19-inch racks, offering flexibility and reliability for small to medium-sized setups.

Why Choose the AP9559?
The AP9559 shines in scenarios where simplicity and affordability are priorities. Unlike switched PDUs (like the AP7922B) that offer remote control or metered models with current monitoring, the AP9559 sticks to the basics—delivering power where it’s needed without extra features that might go unused in smaller setups. Its 16A capacity strikes a balance between entry-level 10A PDUs and higher-end 32A models, making it a sweet spot for moderate-power racks.
For users in regions with 208V or 230V power—like the US, UK, or parts of Europe—the AP9559’s dual-voltage compatibility adds flexibility without requiring custom configurations. While it lacks the advanced management of pricier PDUs, its reliability and ease of use make it a practical choice for small businesses, remote offices, or secondary racks.
Installation and Usage Tips
- Mounting: Secure the PDU in a 1U rack space using the included brackets, ensuring proper alignment and ventilation.
- Power Connection: Plug the IEC C20 input into a compatible 16A power source (C19 outlet or UPS); use a matching power cord if extending beyond the included 3.05m.
- Load Balancing: Distribute devices evenly across the 12 outlets to avoid overloading any single circuit.
- Cable Management: Use rack organizers to keep cords tidy and prevent accidental disconnections.
When to Consider the AP9559
The AP9559 is best suited for:
- Small server rooms or IT closets with basic power needs.
- Environments where remote management isn’t necessary.
- Budget-conscious setups requiring reliable power for up to 12 devices.
If you need remote switching or real-time power monitoring, consider a switched or metered PDU instead. But for straightforward power distribution, the AP9559 gets the job done efficiently.
