How Fault-Managed Power Cuts Labor and Material Costs in Smart Complexes - CleanTechnica

The article from CleanTechnica explores the concept of fault-managed power (FMP), a novel approach to electrical power delivery that aims to combine the safety features of alternating current (AC) with the efficiency advantages of direct current (DC). Originating from American innovation, FMP was developed to make high-voltage power delivery as safe and controllable as data networking by sending DC energy in monitored, short pulses that can be instantly shut off if a fault occurs. This technology, pioneered by companies like VoltServer, has been formally recognized in the 2023 National Electrical Code as Class 4 Fault-Managed Power Systems, enabling broader adoption by major manufacturers and regulatory acceptance in North America, with growing interest in Europe and Asia. FMP can be seen as an evolution of Power over Ethernet (PoE), which transmits low-voltage DC power alongside data over standard network cables to power devices such as Wi-Fi routers and security cameras. While PoE is limited by power output (up to about
