Legrand's Revolutionary Starline T5 DoubleBar

In an era where artificial intelligence (AI) and high-performance computing (HPC) dictate the pace of innovation, effective power distribution becomes crucial. Recognizing this growing need, Legrand has launched the Starline T5 DoubleBar track busway, a cutting-edge solution poised to redefine power infrastructure in high-density environments.

A Solution to Evolving Power Demands

With the exponential increase in power requirements for data centers, Legrand's Starline T5 DoubleBar addresses a crucial gap in the market. This innovative design boasts the highest ampacity among open-channel busways available, capable of supporting demanding environments that surpass traditional infrastructural limits. The dual T5 bar configuration enables up to 2000A, seamlessly catering to the surging power needs typical in modern data centers confronting high-density AI workloads.

The frequency of technological shifts demands adaptability, and here, the T5 DoubleBar excels by offering maximum flexibility without sacrificing power delivery capabilities. According to Mark Swift, Vice President of Engineering for Starline, operators no longer need to choose between heavy, rigid busducts and flexible track busways. The T5 DoubleBar elegantly merges the two, providing robust power density while preserving operational flexibility.

Key Features That Stand Out

The advantages of Starline T5 DoubleBar go beyond just high ampacity. Some of its standout features include:

• - Enhanced Compatibility for AI and HPC: This busway effortlessly manages rack loads reaching 150kW, making it ideal for next-generation data centers. Additionally, it accommodates low-voltage direct current (LVDC) installations up to 1000VDC.
• - Increased Pluggable Space: The innovative dual conductors work in parallel, allowing for heightened amperage and pluggability without increasing the footprint. This change is vital for space-restricted data centers.
• - Zero-Downtime Reconfiguration: A hot-pluggable tap-off feature ensures that operators can install or remove units without interrupting the system’s functionality, enhancing operational continuity.
• - Modular and Scalable Design: This modular infrastructure can be adapted to various ratings without significant redesign efforts and supports future expansions accommodating up to 5000A, protecting long-term investments.
• - Ecosystem Compatibility: The T5 system maintains complete compatibility with existing T5 plug-in units while offering accessible open-channel connections.

Launching Alongside High-Capacity Plug-in Unit

In tandem with the Starline T5 DoubleBar, Legrand is unveiling a new High-Capacity Plug-in Unit (HCP). This unit is explicitly designed for effortless integration with the T5 infrastructure, including the new DoubleBar system. Capable of delivering up to 250A, the HCP simplifies high-density power delivery by reducing the necessity for numerous lower-amperage plugins.

This streamlined power architecture effectively supports AI and HPC racks, optimizing overall efficiency while ensuring that the required power demands are met swiftly and reliably.
