Designing N+1 Redundant Power Systems for Industrial Applications
Learn how to configure hot-swap power modules for mission-critical systems that require 99.99% uptime guarantee.
In industrial and telecom applications, power failure is not an option. A single power module failure can bring down an entire production line or base station.
Understanding N+1 Redundancy
N+1 redundancy means you deploy one more power module than the minimum required load. If one module fails, the remaining modules can handle the full load without interruption.
Key Design Considerations
Current Sharing
The LX-200 features built-in current sharing that supports up to 6 modules in parallel. This ensures balanced load distribution and prevents any single module from being overstressed.
Hot-Swap Capability
OR-ing FETs allow modules to be inserted or removed without powering down the system. This is critical for maintenance in continuous-operation environments.
Monitoring
PMBus interface provides real-time visibility into voltage, current, temperature, and fault status for each module, enabling proactive maintenance.
Example Configuration
For a 2,000W load:
