Legrand has expanded its power distribution lineup with the Universal Input option for its next-generation PRO4X and PX4 Intelligent Rack PDUs, available under the Server Technology and Raritan brands. Announced in February 2025, this update marks an important advancement for data center operators seeking flexibility and consistency across multiple global facilities.
By enabling one PDU model to adapt to various regional power environments, the Universal Input option simplifies deployment, improves efficiency, and reduces operational complexity in data centers of all sizes.
To support these systems and ensure uninterrupted operation, many operators pair them with reliable UPS and power backup solutions available at Saitech Inc.
How the Universal Input Option Works
At the core of this innovation lies a smart recognition system integrated into the PDU and its interchangeable cords. Each input cord contains embedded memory that stores key electrical details such as voltage range, current capacity, and phase information.
When a cord is attached, the PDU automatically reads this data and adjusts its configuration to match the connected power source. This ensures compatibility while maintaining the highest safety standards. Although the process is designed for ease of use, final verification and commissioning should still be carried out by a qualified technician to confirm compliance with local electrical codes.
The system prevents mismatched connections and ensures that the correct voltage and current settings are applied every time. It allows a single PDU model to support single-phase, three-phase Delta, or three-phase Wye power types, providing unmatched adaptability across facilities.
Key Benefits for Data Center Operators
1. Simplified Global Deployment
With the Universal Input option, data center operators no longer need to manage separate PDU models for different regions. A single PDU can be shipped to any site, and the local team simply attaches the correct input cord. This approach streamlines global operations, speeds up installation, and ensures consistent performance across all facilities.
2. Reduced Inventory and Maintenance Costs
Managing multiple model variations increases procurement complexity and warehouse space requirements. By consolidating to one universal model, operators can minimize spare parts inventory, reduce storage costs, and simplify maintenance procedures. The same PDU can be reused or reconfigured for another site when needed.
3. Faster Commissioning and Setup
Time is critical when expanding or refreshing data center capacity. The Universal Input design allows racks to be preassembled with PDUs before knowing the final power type. Once installed on-site, the proper cord is connected, and the PDU automatically configures itself for the available input. This reduces setup time, minimizes manual intervention, and lowers the risk of installation errors.
4. Smart Cord Memory for Automatic Configuration
Each interchangeable input cord is more than just a connector. It includes built-in memory that holds information about voltage, current, and phase. When connected, the PDU reads this data to ensure accurate setup and safe operation. This plug-and-play concept simplifies installation while maintaining reliability.
5. Scalability and Future Flexibility
As data centers evolve or expand, power distribution requirements often change. The Universal Input feature makes PDUs future-ready. If a site transitions from single-phase to three-phase power or undergoes a layout change, the same PDU can remain in use with only the cord replaced. This adaptability supports long-term scalability and reduces hardware waste.
6. Improved Cable Management and Safety
The Universal Input cords are designed with angled connectors that simplify cable routing in dense rack environments. Their keyed connectors ensure that only compatible cords are used, reducing the risk of improper or unsafe connections. This thoughtful design supports cleaner, safer, and more efficient data center environments.
Enhancing Power Monitoring and Energy Efficiency
Legrand’s PRO4X and PX4 Intelligent Rack PDUs, part of the Raritan PDU Collection, already come equipped with advanced power monitoring, outlet-level control, and environmental sensors that help operators track load distribution and energy usage in real time. The Universal Input option extends these capabilities by ensuring consistent performance even when power environments vary between sites.
The Raritan PDUs integrate seamlessly with centralized management platforms, enabling remote monitoring of parameters such as load balance, voltage, and temperature across multiple racks. This visibility helps operators maintain uptime, reduce the risk of overloads, and optimize energy efficiency across the entire data center footprint.
Meeting the Needs of Modern Global Facilities
Enterprises expanding across multiple countries face the challenge of managing different electrical standards. The Universal Input feature provides a standardized approach to power distribution, ensuring uniformity and reliability worldwide.
It also supports emerging deployment models such as edge computing, colocation, and modular containerized facilities, where flexibility and speed are essential. Regardless of the deployment type, Universal Input PDUs simplify configuration, minimize hardware duplication, and uphold consistent safety and monitoring standards.
The Way Forward
The introduction of Legrand’s Universal Input option for its PRO4X and PX4 Intelligent Rack PDUs represents a major leap in simplifying global power distribution. It brings flexibility, consistency, and long-term value to data center operators managing facilities across diverse electrical infrastructures.
By allowing one intelligent PDU model to adapt to multiple power inputs, Legrand removes traditional barriers related to region-specific equipment, streamlining both operations and scalability. The result is a smarter, safer, and more sustainable approach to power management in data centers.
As an authorized Legrand reseller, Saitech offers the PRO4X and PX4 Intelligent Rack PDUs with the Universal Input option, providing data center operators with flexible and reliable power distribution solutions available today.
