APC AP9567 Rack Power Distribution Unit
The APC AP9567 is a basic 100V-120V rackmount PDU providing reliable power distribution with fourteen 5-15R outlets. It supports up to 1.4 kW of output, suitable for mixed server gear, switches, and ancillary devices in a standard 19-inch rack. With a NEMA 5-15P input, this unit emphasizes straightforward power delivery and rack compatibility. It’s a strong choice for data closets or lab setups where a simple, robust power distribution solution is preferred without advanced metering or dual-circuit features.
Tripp Lite Basic PDU, PDUV20
The Tripp Lite PDUV20 is a 0U vertical rackmount PDU designed for 20A, 120V operation with 14 outlets and the L5-20P input. Its 36-inch cord provides flexible placement, and the device supports a mix of 5-15 and 5-20 receptacles via adapters when needed. This model is ideal for compact server rooms or telecom racks where a long cord and vertical mounting maximize space efficiency in a standard 19-inch cabinet.
Tripp Lite Metered PDU, PDUMV40
The PDUMV40 is a metered, 20A dual-circuit PDU with two independent 16-outlet banks. It uses dual L5-20P input options and provides two current monitoring displays, ensuring balanced loading and visibility into power usage. With 32 outlets total and color-coded circuits, this 0U PDU is well-suited for data centers or lab environments that require precise awareness of each circuit’s load and easier fault isolation.
Tripp Lite 16-Outlet 48 Inch Power Strip (PS4816B)
This long, 48-inch vertical/horizontal power strip offers 16 outlets across a 120V, 15A configuration. The 15-foot cord ensures reach in large enclosures or tech rooms, with the ability to mount in either orientation. Its robust metal housing and nine-outlet spacing make it versatile for racks, workbenches, or telecom installations where extensive distribution is needed in a single unit.
APC AP9551 Rack PDU Basic Zero U 20A/120V
The APC AP9551 provides a zero-U form factor with 14 outlets and a 1.9 kW capacity, designed for compact rack environments. Its input supports 100V-120V, and the unit uses a NEMA L5-20P input. This PDU offers straightforward power distribution for dense racks where space is at a premium, making it a practical option for telecom closets and small data centers that require unobtrusive PDUs without extra metering or remote management features.
Buying Guide: Key Considerations For Vertical Rack-Mount PDUs
When selecting a vertical rack-mount PDU, consider the following aspects to ensure the unit aligns with your equipment, space, and operational needs.
- Power capacity and current rating: Match the PDU’s wattage and amperage to the load you expect in your rack. Higher-end devices may offer dual circuits or metering to help balance loads and prevent overloads.
- Number and type of outlets: Count the devices you plan to power and choose PDUs with enough outlets and compatible receptacles (NEMA 5-15R, 5-20R, etc.).
- Metering and monitoring: Metered PDUs display real-time load, aiding capacity planning and energy management. If you don’t need live data, a basic PDU may be sufficient.
- Power input configuration: Consider input plugs (NEMA L5-20P vs. standard NEMA 5-15P) and cord length to fit your cabinet and room layout.
- Physical footprint and mounting style: Ensure the PDU is compatible with your rack’s 19-inch standard and that the 0U or 1U design fits available vertical space.
- Durability and build: Metal housings provide durability for commercial environments, while lighter options may suit home labs.
- Safety and certifications: Look for UL or ETL listings and proper electrical compliance for your region and facility.
- Expandability and redundancy: Consider modular or dual-circuit PDUs if you anticipate growth or require reduced risk of downtime due to a single circuit failure.
- Cost of ownership: Beyond the purchase price, factor in potential energy savings from metered PDUs and the cost of replacement outlets or cords over time.
- Cable management: PDUs with integrated cable hooks or channels can improve airflow and reduce heat buildup.
In summary, for small to medium racks with standard 120V gear, 14-outlet basic PDUs like the APC AP9567 or AP9551 offer dependable distribution. If precise load monitoring is important, metered options such as the PDUMV40 provide dual circuits and monitoring displays. For longer runs or larger racks, the PDUV20 or PS4816B’s extended cords and versatile mounting can reduce installation complexity. Align your choice with the number of devices, required outlets, and whether you need circuit-level visibility or redundancy capabilities to maintain uptime.
