In the world of IT infrastructure, reliable power distribution is the unsung hero that keeps servers humming, networks flowing, and data centers operational. Without it, even the most advanced hardware can grind to a halt. Enter the Rack Power Distribution Unit (PDU)—a compact, efficient device designed to deliver power exactly where it’s needed: inside your server racks. Today, we’re spotlighting a standout in this category: the APC AP9559 Basic Rack PDU. This 1U horizontal unit, rated for 16A at 208V and 230V, features (10) C13 and (2) C19 outlets, making it a go-to choice for small to medium-sized setups. Let’s break down what makes this PDU a reliable workhorse for your rack environment.
What is a Rack PDU, Anyway?
Before we zoom in on the AP9559, a quick primer: A Rack PDU is essentially a power strip on steroids, engineered specifically for mounting in standard 19-inch server racks. It takes a single high-capacity input from your facility’s power source and fans it out to multiple outlets for your IT equipment—like servers, switches, and storage arrays. PDUs come in various flavors: basic (unmanaged), metered (with monitoring), switched (remote control), and more advanced intelligent models.
Basic PDUs, like the AP9559, focus on straightforward, cost-effective power distribution without bells and whistles like remote monitoring or outlet-level switching. They’re ideal for environments where simplicity and reliability trump fancy features, such as branch offices, edge computing setups, or even home labs scaling up.
Unpacking the APC AP9559: Key Specifications
The AP9559 is part of APC by Schneider Electric’s NetShelter Basic Rack PDU lineup, designed to fit seamlessly into your rack without wasting precious space. Here’s a rundown of its core specs:
| Feature | Details |
|---|---|
| Form Factor | 1U horizontal rack-mountable (occupies just one rack unit of vertical space) |
| Input | IEC 60320 C20 connector, 16A maximum, 208V/230V AC single-phase |
| Output Outlets | 10 x IEC 60320 C13 (standard for lower-power devices like switches) + 2 x IEC 60320 C19 (for high-power gear like servers) |
| Power Rating | 3.68 kVA maximum |
| Frequency | 50/60 Hz |
| Cord Length | Approximately 3 meters (10 feet) for flexible placement |
| Dimensions (HxWxD) | 1.72″ x 17.5″ x 4.25″ (44mm x 444mm x 108mm) |
| Weight | About 3.6 kg (8 lbs) |
| Certifications | UL, cUL, CE, and RoHS compliant for global safety and environmental standards |
This PDU draws from a single-phase circuit, converting it into reliable power for up to 12 devices. The mix of C13 and C19 outlets offers versatility: C13s handle everyday peripherals (up to 10A each), while the C19s support power-hungry equipment drawing up to 16A. With a total capacity of 3.68 kVA, it’s rated for environments up to around 3,680 watts—plenty for a standard 42U rack populated with mid-range servers.
Why Choose the AP9559? Standout Features and Benefits
What sets the AP9559 apart in a sea of PDUs? It’s all about balance: robust performance in a no-frills package.
- Space-Saving Design: At just 1U high, it mounts horizontally in your rack using included toolless brackets, keeping airflow unobstructed and U-space efficient. No more clunky power strips dangling from the sides—power stays organized and close to your gear.
- Universal Compatibility: The 208V/230V input works across global standards (think North America, Europe, and beyond), and the outlet mix supports a wide range of plugs. Whether you’re powering Dell servers with C13 cords or HP blades via C19, it’s plug-and-play.
- Reliable Power Delivery: Built with high-quality components, it distributes power evenly without hotspots or voltage drops. Overload protection is baked in via circuit breakers, safeguarding your equipment from surges.
- Easy Installation: Weighing under 4 kg, it’s a breeze to install. The 3-meter cord gives you routing flexibility, and it’s corded for immediate use—no assembly required beyond rack mounting.
In short, the AP9559 excels where downtime isn’t an option but budgets are tight. It’s not “smart,” but it’s dependable—like a trusty extension cord that scales to enterprise levels.
Ideal Use Cases for the AP9559
This PDU shines in scenarios demanding straightforward power without complexity:
- Small Data Centers or Colocation Racks: Distribute power to 8-12 servers in a shared rack, freeing up space for cooling or cabling.
- Branch Offices and Retail IT: Power network closets with switches, routers, and VoIP systems without overkill features.
- Development Labs: For IT pros testing hardware setups, the outlet variety accommodates prototypes and test benches.
- Edge Computing: In remote sites where space and simplicity matter more than remote management.
If your setup grows to need metering or remote rebooting, APC’s metered or switched PDUs (like the AP9565 series) could be a natural upgrade path.
Installation and Maintenance Tips
Setting up the AP9559 is straightforward, but a few pro tips ensure peak performance:
- Rack Planning: Mount it near the top or middle of the rack for even weight distribution and easy access. Ensure at least 1U clearance above for ventilation.
- Power Sourcing: Connect to a dedicated 16A/230V circuit to avoid tripping breakers. Use a UPS upstream for backup power.
- Cable Management: Label cords and use ties to prevent tangles—APC’s PDU pairs well with their NetShelter cable managers.
- Maintenance: Dust it quarterly with compressed air, and check connections annually. No firmware updates needed, but monitor load via external tools if desired.
