Can I parallel connect power supplies for an N+1 redundancy system?
Yes. Parallel connecting powers supplies for operation in Redundant mode is an acceptable and often necessary practise for mission critical applications. To ensure correct operation each power supply must be capable of providing the full system load. The the power supplies should have their outputs connected in parallel via diodes. The diodes permit on power supply to fail without affecting the other. For more details see our Xgen Designers Manual and Application Notes section.
