N+1 Redundancy

N+1 Redundancy 1:

Notes on parallel use for N + 1 redundancy

  • Note that leakage current, EMI, input inrush current and harmonics increase when using multiple devices.
  • The ambient temperature may not exceed +60 °C for N + 1 redundancy systems.

Redundancy systems for higher power requirements are usually set up using the N + 1 method. For example, four devices with a nominal current of 20 A are connected in parallel for a 60 A redundancy system.
