Raritan PX3-5147R 8-Outlet PDU – 120V, 8 x NEMA 5-20R, 1U Rack-Mountable

The Raritan PX3-5147R 8-Outlet PDU is a compact, high-performance power distribution unit designed for modern data centers and dense server racks. Built to simplify power management while delivering reliable, scalable energy distribution, this 1U rack-mountable PDU helps IT teams optimize uptime, balance loads, and reduce electrical risk across multi-server environments. With eight NEMA 5-20R receptacles and a locking NEMA L5-20P inlet, the PX3-5147R provides a secure, efficient solution for powering a diverse fleet of equipment from a single, centralized point. Its Ethernet network interface enables remote visibility and control, so administrators can monitor power usage, configure alerts, and manage outlets without physically accessing the rack. In short, the PX3-5147R is a practical, space-saving power distribution solution that combines robust hardware with intelligent management capabilities to support continuous operations.

• Eight NEMA 5-20R outlets: The PX3-5147R provides eight versatile 120V AC receptacles, allowing you to power a mix of servers, switches, storage devices, and peripherals from a single PDU. This configuration simplifies cabling, reduces clutter, and helps ensure that critical equipment remains powered during maintenance or peak workloads. Each outlet is positioned for easy access and organized cable routing within crowded racks, enabling technicians to connect devices quickly and safely.
• Locking input connection with NEMA L5-20P: The PX3-5147R uses a locking L5-20P inlet for a secure, vibration-resistant power connection. This locking connector minimizes accidental disconnections during busy rack operations, ensuring steady power delivery even in high-traffic environments. The 120V input is compatible with common data-center power configurations, helping to standardize cabling across the facility while maintaining a strong safety profile.
• High-capacity power delivery: With a maximum load of 1900 W and a 120V AC supply, this PDU is designed to support mid-range server deployments and equipment racks without overstressing the electrical circuit. The combination of eight outlets and substantial wattage capacity makes it ideal for medium-density racks where load balancing and redundancy are priorities. The PX3-5147R helps prevent overloads by providing clear visibility into power distribution and enabling smarter wiring strategies across the rack.
• 1U footprint for space efficiency: Engineered for compact data-center environments, the PX3-5147R occupies just 1U of vertical space in standard 19-inch racks. This slim profile frees up valuable rack space for additional hardware while maintaining robust power distribution. The slim, rack-mountable design supports clean, organized cabling, improved airflow, and easier maintenance—crucial factors in achieving reliable data-center operations.
• RJ-45 network management for remote visibility and control: A built-in RJ-45 Ethernet port enables out-of-band monitoring and remote management. Administrators can access the PDU’s management interface, monitor current draw, configure outlets, view event logs, and deploy alerts from anywhere on the network. This capability reduces on-site visits, accelerates troubleshooting, and improves overall energy management across the data center.

How to install Raritan PX3-5147R

• Prepare the rack: Ensure the rack is stable and has a clean 19-inch footprint where the PX3-5147R will be mounted. Verify that the mounting rails are properly aligned and rated for 1U equipment to support the weight and cable management needs.
• Mount the PDU: Slide the PX3-5147R into the rack rails and secure it using the provided screws or mounting hardware. Confirm the unit is firmly in place and that the chassis aligns with standard rack dimensions for proper airflow and accessibility to outlets.
• Connect the power source: Plug a suitable extension or power cord from a compatible 120V outlet into the NEMA L5-20P locking inlet on the PDU. Use a cable that is rated for at least 15–20A and ensure the connection is secure to prevent accidental disconnections during operation.
• Plan outlet distribution: Route cables from servers and devices to the eight NEMA 5-20R outlets. Distribute the load across the outlets to avoid overloading a single circuit. Use cable ties or organizers to maintain clean cable management and to prevent cords from blocking airflow.
• Configure remote management: Connect the RJ-45 management port to your network switch or management network. Access the PDU’s management interface to configure IP addressing (static or DHCP), set up alerts, enable monitoring of current draw, and establish outlet-level control as per your IT policy. Save the configuration and verify that the PDU is reachable from the management console.
