ECOMMENDATIONS FOR
R
EDUNDANCY
Recommendations for the configuration of redundant power systems:
•
Use separate input fuse for each power supply.
•
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.
23.2. 1+1 R
EDUNDANCY UP TO
10A
1+1 Redundancy up to 10A requires two 10A power supplies and one YRM2.DIODE redundancy module.
