Panduit: Fault Managed Power System – Higher Power, Longer Distance & Effective Safety
October 16, 2025
FMPS: The Panduit Fault Managed Power System Is a Safe, Efficient, Reliable & Practical Power Delivery System That Will Go the Distance
The Fault Managed Power System (FMPS) is a novel power delivery system that allows System Integrators to safely provide significant power, over long distances, to remote equipment. The Panduit FMPS is a Class 4 power system that complies with UL 1400-1 Standard for a safer, more reliable, and easy-to-install power delivery system that provides substantial time and cost savings.
Features
- Safe to handle like Class 2 power, substantially more power and distance
- Simple to install, startup, and troubleshoot
- Centralized power for ease of backup, monitoring & control
- Endless Remote Monitoring and control capabilities
- Hot-Swappable Configuration for flexibility and upgradability
- Efficient and sustainable power distribution with low cable losses, less copper, less material
How Does a Fault Managed Power System Work?
The FMPS uses Pulse Current as its power delivery method. The Transmitter converts standard AC power into high voltage DC power, which is further converted into a Pulse Current waveform delivered over a Class 4 multi-conductor copper cable to the Receiver. The Receiver converts the pulse current waveform into +/- 48 VDC power, which can power multiple end devices.
With the ability to monitor faults, the system can safely use higher voltage to deliver power compared to low-voltage systems (Class 2). This allows the FMPS system to have all the safety benefits of low-voltage installations while delivering significantly more power over longer distances than Class 2 systems.
How Much Power & Distance?
Deliver up to 600W per copper pair and up to 2 kilometers away. The Power and distance any system can deliver depend upon the wire size. Toggle between the charts below to see how much power the Panduit FMPS can deliver across a single pair of copper conductors and at what distance compared to Class 2 systems.

Benefits of Fault Managed Power System
- Save Up to 40% on Material Costs: Safe power distribution allows technicians to install the Panduit Fault Managed Power System with less material, for a less costly and faster deployment than traditional power.
- Lower Your Opex with Centralized Power Architecture: The architecture allows centralized power backup for more accessible and less expensive management. Centrally monitor and control your infrastructure to avoid costly site visits.
- Save Up to 60% on Cable Costs: The Fault Managed Power System delivers up to 6 times the power and 30 times the distance of a Class 2 system, reducing the number of copper pairs needed while using a thinner wire gauge.
- Reduce Headend Space & Cooling Requirements: The FMPS safely delivers more power at higher voltage than a Class 2 system and increases the power capacity per RU while reducing the power lost to heat with higher efficiency.
