  • Industry-leading Intelligence
  • Exceptional Flexibility and Density
  • Enterprise-Level Security
  • Extraordinary Reliability


The Intersection of Innovation and Proven Performance

The PX4 continues the Raritan legacy of delivering best-in-class intelligence while introducing a new set of industry-proven hardware and outlet technology. This new feature set supports rapid deployment in changing environments while providing high density, flexibility, and reliability to drive operational excellence.

is a High Density Outlet Technology design that removes unnecessary outlet molding to provide space for more outlets in a PDU for increased rack density.

are a hybrid C13 and C19 outlet accommodating both C20 and C14 power cables in a single flexible outlet.

is an intuitive outlet and power cord locking system.

promotes input power cord accessibility to ease deployments.

High Density Outlet Technology (HDOT)

is engineered and patented to eliminate the molding around an individual outlet and uses module grouping to fit more outlets into the same space. HDOT outlets require less space than standard PDU outlets, allowing for maximum outlets in a 42U PDU.

One pair of PX4 PDUs with HDOT outlets evenly distributed across the PDU can accommodate dense configurations where three or four PDUs would have been necessary.

HDOT Cx Outlets

are industry-awarded and patented technology that creates a hybrid IEC C13 and C19 outlet that can accommodate C20 and C14 power cables without additional parts or adapters.

When server or storage refreshes occur, PX4 PDUs provide the most outlets with the right outlet mix in the right locations on one single wide PDU. This ensures ultimate density and flexibility while reducing complexity and costs associated with the purchase of new PDUs when future equipment updates occur.

RamLock Mechanical Locking

is a rugged and high-strength outlet and cord-locking system that mechanically secures C14 and C20 plugs to your PDU without requiring special cables, sleeves, or adapters.

It allows for quick and intuitive installations and unplugging with a one-handed “squeeze and pull” action that prevents unintended downtime due to power cords becoming unintentionally unplugged.

The 45-Degree Angled Infeed

is a flexible infeed cord design that improves infeed accessibility and reduces the number of PDU configurations needed.

Wherever you feed your cabinet’s branch circuit power, the PX4’s angled infeed is a one-size-fits-all solution that supports end or front entries to position the PDU where needed, simplifying your deployments while saving time and money.


Breaking Boundaries in Hardware Design & Intelligence

The PX4 builds on the intelligence and reliability of the Xerus™ Technology Platform by adding a revolutionary combination of new hardware and software technologies. These new features ensure mission-critical uptime, real-time visibility, and alerting of power metrics at the cabinet or outlet level.

The iX Controller

is the PX4’s center of intelligence that houses a state-of-the-art network interface module, user-configurable firmware, a high visibility display, and multiple connectivity ports. It offers industrial-grade reliability and multilayer redundancy for failover support.

The iX is fully hot-swappable; it enables live replacement with no power interruption to the individual outlets. It's the most powerful, reliable, scalable, secure, and easy-to-use controller platform.


Advanced Power Quality Monitoring and Metrics

give real-time insight with ±0.5% metering accuracy into critical power quality, energy efficiency, and equipment health at the cabinet. The PX4 offers the most complete and accurate set of power quality monitoring and metrics like total harmonic distortion, reactive power, phase angle, displacement power factor, apparent energy, and inrush current measurements.

Confidently address capacity planning, environmental optimization, failover planning, troubleshooting initiatives, and much more within one intelligent rack PDU.

Total Harmonic Distortion

measurements and monitoring allow you to see how much your electrical load is distorting the power provided by your facility. You can closely monitor and visualize harmonic events like voltage dips and swells, crest factor, and much more.

When coupled with Waveform Capture, you have intuitive visualizations of the power being fed to the PDU or distributed to the PDU's outlets. Having this capability at the Rack PDU helps you to ensure your data center’s rack power is running efficiently.

Circuit Breaker Trip Forensics with Waveform Capture

ensures that when a PDU circuit breaker trips, you have intuitive waveform visualizations with data insights to quickly understand which outlet caused the trip event. 

When coupled with an outlet power on prevention tool called Trip Cause Outlet Handling, you can isolate defective equipment and restore power faster to non-offending devices.


Technology That Transforms Rack Power Distribution

The PX4 is more than just a rack power distribution unit. It is a unified rack PDU solution that provides forward-thinking tools, sensors, and insights to solve ever-evolving infrastructure challenges. It facilitates power management, environmental monitoring, network security, capacity planning, change management, and much more.

maximizes data center efficiency by delivering security, high compute power, advanced alerting, and complete visibility into your power chain.

protects your most valuable hardware and network with unmatched enterprise-level security.

Largest in-house team dedicated to addressing your custom rack power requirements.

The Xerus Technology Platform

is a combination of hardware, software, and communication technologies embedded in all Raritan power solutions. It offers interoperability with third-party systems and connects to a whole ecosystem of accessories, including environment monitoring, asset management, and physical access control accessories.

Rather than managing multiple systems using different protocols, the Xerus Technology Platform supports networked SNMP, MODBUS, open REST based APIs, and a Redfish® API, enabling wherever-you-go monitoring and visibility into your data center rack power operations.


The PX4’s Enhanced Security Suite

includes end-to-end encrypted communications and a secure firewall to control user access. It also stores valid and updated certificates to secure the PDU on public networks. The PX4 also includes Secure Boot, a startup security check that prevents malware from taking over the firmware of the PDU by preventing unauthorized software from taking control at startup.

Security is a core focus for the PX4. Its enterprise-level security stack is designed and engineered to keep you, your assets, and your organization ahead of changing security threats while ensuring that you can grant access to the right individuals when and where needed.
