22. APPLICATION NOTES
22.1. RECOMMENDATIONS FOR REDUNDANCY
Recommendations for the configuration of redundant power systems:
• Use separate input fuse for each power supply.
• It is desirable to set the output voltages of all power supplies to the same value to avoid a false signal of the
DC-ok signal.
• Use Three-phase power supplies to gain functional safety if one phase fails.
• When Single-phase power supplies are utilized connect them to different phases or mains circuits.
• Use both inputs in parallel for currents above 10A.
22.2. 1+1 REDUNDANCY UP TO 10A
1+1 Redundancy up to 10A requires two 10A power supplies and one YR2.DIODE decoupling module.
