• Outlet-level billing-grade accuracy—The Eaton ePDU G3 delivers precise measurements at each outlet, enabling exact chargeback, capacity planning, and proactive load management. Real-time current, voltage, power, and energy data are surfaced through a local LCD pixel display and can also be accessed across the network for centralized monitoring. This level of granularity helps IT and facilities teams make smarter decisions about how servers, storage, and network gear are powered and wired in dense racks.
• 0U rack-mount design with robust power capability—A space-efficient, 0U form factor fits neatly into even the tightest racks while delivering strong distribution performance. The unit uses a three-phase input (L21-20P) and supports a maximum of 5.76 kW, making it suitable for high-density deployments. With a 10 ft cord, it provides flexible reach from the power source to the rack, reducing the need for additional power distribution hardware and simplifying cable management.
• Comprehensive management and analytics—Beyond local readings, the G3 PDU offers advanced management through network connectivity. This enables remote monitoring, configurable alerts, and detailed analytics for load balancing and capacity planning. IT teams gain end-to-end visibility into power usage patterns, allowing more accurate forecasting, improved service levels, and better energy efficiency across the data center footprint.
• Reliable, scalable power distribution for data centers—With 18 C13 outlets and 6 C19 outlets, the PDU distributes power to a wide range of servers, storage devices, and network equipment. The three-phase input and distributed outlets are arranged to support dense rack configurations while maintaining safe, organized cabling. The combination of high-accuracy metering, dependable physical design, and flexible management makes it a core component of a scalable data center power strategy.
• Versatile, future-ready solution for dense racks—The Eaton ePDU G3 is designed for environments that demand precise energy accounting, operational efficiency, and straightforward integration with existing management workflows. Its combination of outlet-level monitoring, local display, and network access makes it an ideal fit for data centers, labs, edge deployments, and any space-conscious facility seeking precise, actionable power information and simplified administration.

How to install Eaton ePDU G3

• Prepare the rack—Ensure compatibility with a 0U PDU and confirm that the rack has adequate mounting provisions and a clear path for cabling. Verify that the rack can safely accommodate the 10 ft input cord and the outlet layout without obstructing air flow or hardware clearance.
• Mount the PDU—Secure the Eaton ePDU G3 into the rack, aligning with the mounting rails. Use the provided hardware to fasten it firmly, ensuring stability and ease of access to outlets and the local LCD display.
• Connect to the power source—Attach the L21-20P input cord to a three-phase power supply that matches the PDU’s specifications (16A). Ensure the facility power is de-energized during connection, then re-energize to begin monitoring.
• Distribute loads—Connect IT devices to the available C13 and C19 outlets, planning load distribution to avoid exceeding the PDU’s maximum rating. Spread high-draw equipment across multiple outlets to optimize performance and cooling in the rack.
• Configure monitoring—Power on the unit and access the local LCD display to verify readings. If network monitoring is desired, configure the PDU for remote access and enable outlet-level monitoring, thresholds, and alerting according to your data center policies.
• Validate operation—Check that current, voltage, power, and energy are reporting correctly for each outlet. Confirm that remote monitoring tools can pull data from the PDU and that alerts and billing-grade metrics are functioning as intended.
