Benefits of the AP9559

1. Cost-Effective Power Distribution

Priced lower than metered or switched PDUs (typically £150–£300 or $260–$339), the AP9559 offers an affordable solution for distributing power to multiple devices using a single branch whip, reducing installation costs.

2. Versatile Connectivity

The combination of 10 C13 and 2 C19 outlets supports a wide range of equipment, from low-power networking devices to high-power servers, making it suitable for diverse IT setups.

3. Space-Saving Design

The 1U form factor minimizes rack space usage, leaving room for critical equipment. Its lightweight design (2.16 lb) simplifies installation and handling.

4. Global Compatibility

With support for 200V, 208V, and 230V inputs and outputs at 120V, 208V, or 230V, the AP9559 is adaptable to various power environments, making it ideal for data centers worldwide.

5. Reliable and Simple

As a basic PDU, the AP9559 focuses on dependable power delivery without the complexity of advanced features, making it a low-maintenance option for environments where monitoring or remote control is not required.

6. Easy Installation

The included rack-mounting brackets and toolless mounting options simplify setup. Optional use of the APC Cord Retention Bracket (AP9569) prevents accidental disconnections, enhancing reliability.

Installation Process

Installing the AP9559 is straightforward and requires minimal tools:

  1. 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 fitment issues with brackets.
  2. Connect the Input: Plug the IEC-320 C20 input cord into a compatible 16A, 208V, or 230V power source.
  3. Connect Devices: Attach up to 10 devices to the C13 outlets and up to 2 high-power devices to the C19 outlets.
  4. Secure Cords: Optionally use the APC Cord Retention Bracket (AP9569) to prevent accidental disconnections.
  5. Verify Operation: Ensure all connected devices receive power and check for proper grounding.

For detailed instructions, refer to the AP9559 Product Datasheet or Schneider Electric’s support resources.

Practical Considerations

Before purchasing the AP9559, consider the following:

  • Compatibility: Verify that your rack environment supports a 1U PDU with an IEC-320 C20 input and C13/C19 outputs. Ensure devices operate at 208V or 230V (or 120V for specific outputs).
  • Basic Functionality: The AP9559 lacks advanced features like remote monitoring or outlet switching found in models like the APC AP7922B. If these are needed, consider APC’s Metered or Switched Rack PDUs.
  • Power Requirements: Confirm that your total load does not exceed 3680VA (230V) or 3328VA (208V) to avoid overloading the PDU.
  • Optional Accessories: The APC Cord Retention Bracket (AP9569) is sold separately for securing cables. Consider this for high-vibration environments.
  • Warranty: The 1-year warranty covers repair or replacement. Verify terms with your retailer, as some may offer extended support options.
