The Class F3 Electrical system offers a smart, balanced design for data centers that require both resilience and flexibility. Here’s how Class F3 architecture can support critical infrastructure needs and ensure power continuity. Class F3 Single Utility Source with Two Utility Inputs considered for the design.

𝗗𝘂𝗮𝗹 𝗥𝗲𝗱𝘂𝗻𝗱𝗮𝗻𝘁 𝗣𝗼𝘄𝗲𝗿 𝗣𝗮𝘁𝗵𝘀:

With Class F3, each critical load has two power paths—only one of which needs to be UPS-powered. The second path is dedicated to IT loads, offering flexibility and cost savings. For dual-corded IT devices, one input is UPS-backed, while the other uses a non-UPS source, achieving redundancy without excessive power costs.

𝗖𝗼𝗻𝗰𝘂𝗿𝗿𝗲𝗻𝘁𝗹𝘆 𝗠𝗮𝗶𝗻𝘁𝗮𝗶𝗻𝗮𝗯𝗹𝗲 𝗦𝘆𝘀𝘁𝗲𝗺:

Class F3 is designed for seamless operation during planned maintenance. The setup provides continuous power during maintenance activities while temporarily reducing redundancy—ensuring uninterrupted service and efficient resource allocation.

𝗨𝘀𝗶𝗻𝗴 𝗦𝘁𝗮𝘁𝗶𝗰 𝗧𝗿𝗮𝗻𝘀𝗳𝗲𝗿 𝗦𝘄𝗶𝘁𝗰𝗵𝗲𝘀 (𝗦𝗧𝗦) 𝗳𝗼𝗿 𝗦𝗶𝗻𝗴𝗹𝗲-𝗖𝗼𝗿𝗱𝗲𝗱 𝗟𝗼𝗮𝗱𝘀:

STSs are required for single-corded IT devices, providing critical power redundancy where IT components don’t inherently have it. For dual-corded devices, STSs aren’t necessary, allowing a more adaptable, simplified power design.

This resilient Class F3 design removes 𝘀𝗶𝗻𝗴𝗹𝗲 𝗽𝗼𝗶𝗻𝘁𝘀 𝗼𝗳 𝗳𝗮𝗶𝗹𝘂𝗿𝗲, ensures transparent maintenance, and provides a reliable power solution capable of supporting IT continuity with a thoughtful balance of redundancy and efficiency.
