Fault Managed Power White Paper

Introduction The Challenge: The digitalization of our economy coupled with sustainability imperatives are fundamentally changing power distribution requirements and energy consumption patterns. This evolution, driven by AI computing demands, edge deployments, and renewable integration, among others, requires new approaches to power delivery and management. A Solution Emerges: Class 4 Fault Managed Power (FMP) is touch-safe and delivers high-power distribution and can be paired with data. FMP is recognized for safely delivering Direct Current (DC) power over longer distances while improving on the safety standards of traditional power-limited circuits. • National Electrical Code (NEC 2023) Article 726 [1] • Underwriters Laboratories (UL) 1400-1 and UL 1400-2 Class 4 system requirements • The Alliance for Telecommunications Industry Solutions (ATIS) • National Fire Protection Association (NFPA) Breaking Through Traditional Power Limitations with FMP: A new era in power distribution The evolution of digital infrastructure and the rising demand for renewable energy requires a fundamental shift in how we deliver and manage power. Fault Managed Power (FMP) represents a breakthrough technology that transforms traditional power distribution constraints into opportunities. By enabling safe delivery of high-voltage DC power up to 450V over extended distances, FMP addresses critical challenges facing modern facilities, from AI-driven data centers to smart buildings and telecommunications infrastructure. Transformational Power Distribution FMP redefines what's possible in power distribution through its innovative approach to delivering and managing high-voltage DC power. • Simplified infrastructure through elimination of traditional electrical requirements • Flexible deployment supporting varied power needs from 100W to multiple kilowatts • Scalable architecture supporting future power demands Transformational Benefits FMP offers compelling strategic benefits that can transform how organizations approach their power infrastructure and sustainability goals. • High-voltage DC power delivery (up to 450V) over greater distances • Active fault management facilitates safe high-power distribution

• Reduced conversion losses through DC power delivery • Advanced power monitoring and management capabilities • Lower installation and maintenance costs • Improved space utilization through reduced infrastructure • Direct integration with DC power sources (solar, fuel cells) • Efficient energy storage system integration • Enablement of microgrid architectures • Simplified path to Net Zero goals
