Legrand Raritan iX Rack-PDU 0U with 12xC13 / 12xCX, single-phase 100-240V 16A, Input Metered (PX4-13A8C-C8E7A0)

Why a vertical 0U PDU is the ideal solution for dense rack environments

In data centers and server rooms with high device density, every rack unit is valuable. Vertical 0U rack PDUs such as the Legrand Raritan iX Rack-PDU 0U (PX4-13A8C-C8E7A0) solve this problem elegantly: by mounting to the side of the cabinet they do not occupy rack units yet still provide 24 outlets for power distribution. With billing-grade metering (class 0.5), branch circuit monitoring and full remote management over Gigabit Ethernet, the PX4-13A8C-C8E7A0 offers all the functions of an intelligent PDU — with minimal rack space usage. The single-phase design with 100–240 V and 16 A is ideally suited for standard IT environments where three-phase power is not required. The color matrix LCD display with auto-flip function allows direct reading of voltage, current and real power on the device — regardless of the installation orientation. The hot-swappable controller ensures uninterrupted maintenance and increases the availability of the power infrastructure during operation.

Which use cases are typical for a 0U PDU with 24 outlets?

A vertical 0U rack PDU with high outlet density is particularly suitable for environments where many devices need to be powered at the same time: colocation racks, high-density computing environments, network cabinets with numerous switches and patch panels, and server rooms where every rack unit is used for active IT components. The Legrand Raritan PX4-13A8C-C8E7A0 combines 12x C13 and 12x CX outlets with mechanical plug locking for maximum operational safety and thus minimizes the risk of unintended interruptions. The alternating branch distribution ensures an even load distribution across the individual branch breakers and prevents local overloads. In data centers with increasing rack density, vertical mounting enables neat cable routing along the rack sides, preventing obstruction of the cabinet airflow — an important factor for cooling efficiency and the energy-efficient operation of the entire IT infrastructure.

How does PDU linking simplify the management of multiple rack PDUs in the data center?

In larger data centers with many racks and PDUs, managing individual devices quickly becomes a significant effort. The Raritan iX Rack-PDU 0U (PX4-13A8C-C8E7A0) supports PDU linking: up to 8 PDUs can be combined into a single management unit so that energy and power data from all linked devices can be retrieved via a central interface. Additionally, up to 32 PDUs can be cascaded over a single Ethernet port — for a scalable, IP-efficient infrastructure in modern data center environments. Redundant power via the first expansion PDU ensures that the primary PDU continues to provide data even if it experiences its own power failure. Through Redfish API, SNMP v3, MODBUS-TCP and JSON-RPC, all measurement data is available to DCIM platforms, automated monitoring systems and capacity planning tools in real time. Automated provisioning via TFTP, DHCP and SSH as well as data logging via MQTT round off the comprehensive feature set of the Raritan iX series and enable efficient scaling of the power infrastructure even in large data center projects. The maximum ambient temperature of 60 °C at full load underlines the robustness of the PX4-13A8C-C8E7A0 even under demanding thermal conditions. Whether in a climate-controlled data center or in edge computing environments with limited cooling — the Legrand Raritan iX PDU delivers reliable power distribution and precise measurement data under all operating conditions. CE and UL certification confirm compliance with international safety standards and facilitate deployment in different countries and regulatory environments. The iOS and Android app also enables mobile access to all measurement data and alerts — ideal for administrators who want to stay informed about their power infrastructure while on the go.
