Benefits and Key Differentiators Summary

As shown, FMP offers several significant advantages over traditional power classifications. At a foundational level, FMP provides greater power delivery capabilities with voltage support up to 450V DC and no inherent power limits beyond cable capacity, enabling power delivery over distances several times greater than Class 2 or 3 systems. The installation process is simplified compared to traditional AC systems, requiring fewer infrastructure components and enabling deployment by a limited-energy technician - also known as a Low-Voltage Technician or Power-Limited Technician. FMP's active fault management approach provides superior safety while eliminating the need for extensive physical protection measures required in traditional power installations.

As a key enabling technology in driving towards lower energy consumption, FMP can help eliminate many of the AC-DC power conversions occurring in today's environment, which can help eliminate 10- 20% of a building's energy consumption. [9] The technology's built-in monitoring and control capabilities enable dynamic load balancing and comprehensive power management. These benefits collectively address the limitations of existing power classifications while providing a pathway for organizations to meet increasing power demands more efficiently and sustainably.​
