When it comes to keeping your IT infrastructure running smoothly, power distribution might not be the flashiest topic—but it’s absolutely essential. The APC Rack PDU, Basic, 1U, 16A, 208&230V, (10)C13 & (2)C19 (AP9559) is a no-frills, reliable solution for delivering power to your rack-mounted equipment. Designed by APC, a Schneider Electric brand synonymous with quality, this basic power distribution unit (PDU) is a workhorse for server rooms, data centers, and small IT setups. Let’s break down what the AP9559 offers and why it’s a solid choice for straightforward power needs.
What is the AP9559?
The AP9559 is a 1U, rack-mounted PDU that provides basic power distribution without the bells and whistles of more advanced models. It’s built to handle 16A at 208V or 230V, feeding power to 10 IEC C13 outlets and 2 IEC C19 outlets via an IEC 320-C20 input connector. With a 2.5-meter (8.2-foot) cord, it’s designed to slot into a standard 19-inch rack, delivering up to 3.68kVA of power to servers, networking gear, and other critical devices.
This is a “basic” PDU, meaning it skips features like remote monitoring or switched outlets in favor of simplicity and affordability. It’s all about getting power where it’s needed most—right to your rack equipment—without complicating things.
Key Features of the AP9559
- Compact 1U Design: Occupying just one rack unit (44mm high), the AP9559 maximizes space in cramped server racks, leaving room for your core equipment.
- Versatile Outlets: With 10 C13 outlets (common for smaller devices like switches and servers) and 2 C19 outlets (for higher-power gear like blade servers or storage units), it accommodates a range of equipment in one unit.
- Flexible Input: Supports both 208V and 230V input (50/60Hz), making it adaptable to different power environments, from North American data centers to European setups.
- Long Cord: The 2.5-meter power cord gives you flexibility in rack placement, reducing the need for extension cables.
- Horizontal Mounting: Designed for horizontal installation, it’s easy to integrate into standard 19-inch racks with included mounting brackets.
- Durable Build: Weighing about 2.5kg, it’s sturdy enough to handle the demands of a busy rack environment.
Why Choose the AP9559?
- Simplicity: No complex setup or software required—just plug it in and power up. It’s perfect for users who don’t need remote management or metering.
- Cost-Effective: Compared to switched or metered PDUs, the AP9559 offers essential power distribution at a lower price point, typically ranging from £250–£350 depending on the retailer.

Why Go with APC?
While generic PDUs might tempt you with lower prices, the AP9559 carries APC’s reputation for reliability and durability. It’s tested to meet Schneider Electric’s high standards, ensuring consistent performance. Plus, APC’s commitment to sustainability—think recyclable packaging and take-back programs—adds a responsible edge to your purchase. The 2-year warranty further sweetens the deal, offering peace of mind for your investment.
Limitations to Consider
The AP9559’s simplicity is its strength, but it’s not for everyone. If you need remote control, power metering, or outlet-level switching, you’ll want to look at APC’s Switched or Metered PDU lines (like the AP7922B). It also lacks surge protection, so in surge-prone areas, you might pair it with a separate protector. For basic needs, though, it’s hard to beat.
