模組化資料中心測試與認證

模組化資料中心製造商可透過 UL 2755《模組化資料中心調查大綱》，提升對客戶的價值並維護其品牌聲譽。

依據《美國國家電工法規》（NEC）第 646 條，製造商可透過 UL 2755 認證，一次性滿足對預製資料中心的多項要求，前提是在模組化資料中心出貨至安裝地點之前即完成認證。這樣可減少購買方需在現場進行檢驗與認證的負擔。對製造商而言，這項認證提升產品的合規性信任度，讓客戶能夠放心使用。此外，若產品在交付後因後續操作導致不再符合標準，UL 2755 認證也可協助製造商降低相關責任風險。

簡化合規流程

UL Solutions 參與制定 UL 2755 調查大綱，以滿足資訊技術產業相關利益方的需求，包括設備製造商、使用者、具管轄權的主管機構（AHJ）及 UL Solutions 電氣委員會成員。UL 2755 將資料中心內的各個組件視為一個整體系統，可認定為單一產品。如此一來，經認證的設備只需在現場進行安裝檢查即可，因為整個資料中心機組已經符合合規性要求。

NEC 第 646.4 條亦將 UL 2755《模組化資料中心》做為確認符合 UL 列名要求的方法之一。

超越 IEC 62368-1 的防護

IEC 62368-1 是資訊技術設備的核心安全標準，涵蓋電擊、消防、機械及其他相關風險。而 UL 2755 則針對安裝於模組化資料中心的資訊技術設備的安全，涵蓋配電、冷卻系統、結構強度及運輸安全等方面。此外，UL 2755 考量人員的人身安全，確保在維護作業期間，進入資料中心的技術人員能獲得適當的防護。這包括照明設計、工作空間規劃、緊急出口及警報系統等安全規範。

UL 2755 參考《美國國家電工法規（NEC，NFPA 70）相關條文，以確保符合電氣安全要求。

Key features of UL 2755:2025 include:

Module type categorization and system integration
Precise testing addresses the safety risks for each module’s functions and applications.
Comprehensive code compliance framework
Evaluation to comprehensive compliance requirements with multiple code systems beyond building and fire codes can help streamline approvals with complex authority having jurisdiction (AHJ) requirements.
Enhanced construction and structural requirements
Comprehensive safety testing to structural engineering requirements includes stacking loads, lifting specifications and seismic considerations — crucial for large-scale data center deployments.
Streamlined pathway to compliance
Our structured process includes a request for quote (RFQ), preliminary review for compliance to UL 2755, preliminary findings and full evaluation to UL 2755.

Why work with UL Solutions?

Leverage our deep technical expertise as you build safer infrastructure that can keep up with modern hyperscale data center requirements.

Available exclusively through UL Solutions, the 2025 edition reinforces us as your trusted provider — helping you navigate safety and compliance challenges and accelerate the deployment of prefabricated MDCs.

What is a modular data center (MDC), and how does it differ from a traditional data center?: An MDC is a prefabricated structure designed for faster deployment, scalability and efficiency in meeting data center workload demands, contrasting conventional brick-and-mortar data centers, which require longer construction times. Legacy facilities and infrastructure may not be designed to meet the performance demands and requirements for modern AI data centers.
What are the primary safety risks associated with data centers?: The main safety risks include more destructive arc flashes associated with higher power densities, rapid overheating stemming from increased thermal loads and overtaxed cooling systems, and flammable liquid leaks from liquid cooling systems — all of which introduce significant fire risks.
What is UL 2755, and why is it important for modular data centers?: UL 2755, the Outline of Investigation for Modular Data Centers, is referenced in Article 646 of NFPA 70 — the National Electrical Code® (NEC). UL 2755 addresses safety challenges and enables manufacturers to have prefabricated MDCs evaluated efficiently, as a single integrated product. This helps streamline the approval process with AHJs. UL Certified MDCs typically require only evaluation of proper installation in the field, whereas without UL 2755 Certification, local code authorities would likely need to conduct additional evaluations.
What changes have been made to UL 2755?: The updated edition, UL 2755:2025, provides a comprehensive safety framework that addresses real-world deployment scenarios while remaining flexible to support technological innovation in modern prefabricated MDCs and the increased capacity required for AI-driven workloads.
Key updates include robust module type categorization, a comprehensive code compliance framework and enhanced construction requirements. As a proprietary OOI available exclusively through UL Solutions, UL 2755:2025 positions us as your provider of choice — helping you demonstrate safety and compliance for prefabricated MDCs and supporting their rapid deployment.
