Selecting a power distribution unit (PDU) for a server rack seems simple. But what if you want a single PDU that can serve multiple regions and support multiple rack configurations?
For example, in terms of inputs, designers for global deployments need to consider various power architectures. This may be a problem for pre-integrated rack manufacturers because they want to have a universal chassis that can be deployed globally without worrying about voltage or plug type differences.
Similar problems exist at the output. Now, more and more high-power equipment is mixed with standard IT equipment in racks. Adapting to these unpredictable combinations is challenging for systems integrators, multinationals, and other business organizations that want to unify PDU standards to simplify supply chain and inventory management.
Finally, PDU plays a crucial role in system management. The addition of metering and monitoring capabilities to the PDU can provide a powerful advantage, but doing so can create security vulnerabilities.
A Rack PDU Using Universal Inputs -- Introduction to UPDU G4
To address these challenges, Tripp Lite by Eaton developed the UPDU G4 Series Universal PDU (UPDU). The family combines global electrical compatibility, multi-function C39 sockets, and security management functions to provide a standalone solution for the needs of a data center.
The UPDU G4 features flexible input. The equipment is suitable for single - and three-phase architectures at 208 volts and 415/240 volts and is suitable for racks with power requirements up to 23 kilowatts (kW).
Movable input cable improves input flexibility. These cables are sold separately. Eaton offers 17 input cables and 15 different types of plugs for global deployment of the UPDU G4 by simply selecting the appropriate cable.
Flexibility is also a characteristic of the output side. The UPDU G4 supports up to 42 sockets and can be mixed:
C13 socket, pluggable with most C14 plugs for IT equipment
C39 socket, which can plug C20 plug with larger power or traditional C14 plug
Finally, the UPDU G4 series also includes models that support metering, monitoring, and switching by socket. To guarantee these functions, powerful network security measures, including trust chain encryption and security firmware startup, are taken to ensure that PDU will not become a weak point of the network.g.
Remote management function of advanced rack PDU
EVMAGU23X (Figure 1) shows the functions of the UPDU G4 series. This rack-mounted PDU is 72.00 x 2.00 x 2.56 in. (182.88 x 5.08 x 6.50 cm) in size with 42 sockets and a thin design allows it to be neatly mounted in a standard 42U rack.

The 42 sockets are divided into 24 conventional C13 sockets and 18 high reserved C39 sockets. The sockets are divided into six load groups, each of which is equipped with an independent circuit breaker to improve load balancing and orderly wiring in high-density cabinets.
One of the main functions of EVMAGU23X is to support remote management. The PDU includes a hot swap gigabit network module (GNM), which can separately measure and switch 42 sockets. For example, if a server hangs, EVMAGU23X can cycle power to the server without affecting other parts of the rack. To ensure that remote access does not result in network vulnerabilities, this module integrates powerful network security features, including zero trust architecture and zero contact provisioning.
With these features, EVMAGU23X can be managed via a web browser or integrated into the Data Center's Infrastructure Management (DCIM) system. Users can also use Eaton's Brightlayer Data Center Suite to manage software or third-party tools. Using these functions together can significantly reduce the need for on-site operation and maintenance, which is critical for distributed data centers and edge networks.
