Manufactured by Schneider Electric, this basic PDU provides straightforward power distribution for rack-mounted equipment in server rooms, data centers, and network closets. In this blog, we’ll dive into its key features, performance, applications, and overall value to help you determine if it’s the right choice for your infrastructure.
Key Features
1. Compact 1U Design
The AP9559 is a 1U horizontal rack-mounted PDU, measuring approximately 44.7 cm x 5.7 cm x 4.5 cm (17.6 x 2.24 x 1.77 inches) and weighing about 0.98 kg (2.16 lbs). Its compact form factor ensures minimal space usage in server racks, making it ideal for environments where space is at a premium. The black, durable enclosure supports both front and rear mounting, offering flexibility for various rack configurations.
2. Versatile Outlet Configuration
This PDU features 12 outlets: 10 IEC 60320 C13 and 2 IEC 60320 C19 connectors. The C13 outlets are suitable for standard IT equipment like servers and networking devices, while the C19 outlets support high-power devices such as enterprise-grade servers or storage systems. This combination provides flexible connectivity for diverse equipment needs.
3. High Power Capacity
The AP9559 supports a 16A input current with a nominal input/output voltage of 208V and 230V, delivering a maximum load capacity of 3.68kVA (3680VA) at 230V. This makes it suitable for medium-density power requirements in enterprise and data center environments. The PDU uses an IEC-320 C20 input plug with an 8.2 ft (2.5 m) cord, ensuring easy integration with standard power sources.
4. Reliable Power Distribution
As a basic PDU, the AP9559 focuses on delivering power from a single branch whip to multiple devices without advanced features like remote monitoring or outlet control. This simplicity reduces costs and complexity, making it ideal for environments where straightforward power distribution is the primary need. The PDU is designed to save time and money during installation by using standard connections.
5. Global Safety Certifications
The AP9559 is compliant with global safety standards, including UL 60950, cUL Listed, CE, and VDE. This ensures reliable and safe operation across diverse environments. It operates within a temperature range of 32°F to 113°F (0°C to 45°C) and supports altitudes up to 10,000 ft, making it adaptable to various conditions.
6. Eco-Friendly Design
The PDU is packaged with recycled cardboard (minimum 70% recycled content, 50% in the US), reflecting Schneider Electric’s commitment to sustainability. It is also part of APC’s global take-back program in select regions, allowing for responsible disposal or recycling. The unit has a carbon footprint of 29 kg CO2 eq. over its lifecycle, aligning with environmentally conscious practices.
7. Easy Installation
Installing the AP9559 is straightforward and requires minimal tools:
- Mount the PDU: Secure it in a 1U rack space using the included rack-mounting brackets. Some users note minor fitment issues with the brackets, so proper alignment is key.
- Connect the Input: Plug the IEC-320 C20 cord into a compatible 16A, 208V or 230V power source.
- Connect Devices: Attach up to 10 devices to the C13 outlets and 2 high-power devices to the C19 outlets.
- Secure Cords: Optionally use the APC Cord Retention Bracket (AP9569) to prevent accidental disconnections.
- Verify Operation: Ensure all devices receive power and check for proper grounding.
The package includes a user guide, rack-mounting brackets, and a safety guide for hassle-free setup.
Performance
The AP9559 is designed for reliable power distribution rather than advanced functionality. It efficiently distributes power to connected devices with a maximum capacity of 3.68kW, supporting a variety of IT equipment. Its 50/60 Hz input frequency ensures compatibility with standard power grids worldwide. While it lacks the metering or remote control capabilities of higher-end PDUs like the APC EPDU1016M or AP8858, its performance is consistent for basic power needs.
Reliability and Build Quality
Manufactured by Schneider Electric, the AP9559 is built for durability and reliability. Its robust design ensures consistent power delivery, and the included 2-year warranty provides peace of mind. However, some users report that the mounting brackets could be sturdier compared to competitors like Siemens or HP. Despite this, the PDU’s price-to-performance ratio remains competitive, making it a cost-effective choice for small to medium-sized setups.
Applications
The AP9559 is well-suited for:
- Small to Medium Server Rooms: Distributes power to servers, networking equipment, and storage systems.
- Network Closets: Provides reliable power for switches, routers, and other critical infrastructure.
- Edge Computing Sites: Supports compact IT deployments in remote or branch offices.
- Data Centers: Serves as a cost-effective solution for medium-density power needs.
For users requiring advanced features like remote monitoring or outlet-level control, alternatives like the APC AP7921B (switched) or AP8841 (metered) may be more suitable, though they come at a higher cost.
