18. APPLICATION NOTES
18.1. RECOMMENDATIONS FOR REDUNDANCY
Recommendations for the configuration of redundant power systems:
• Use separate input fuses 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 if possible.
• Set the power supply in “Parallel-Use” mode if this feature is available
• It is desirable to set the output voltages of all power supplies to the same value.
18.2. INDUCTIVE AND CAPACITIVE LOADS
The unit is designed to supply any kind of loads, including unlimited capacitive and inductive loads.
18.3. EXAMPLE: 1+1 REDUNDANCY UP TO 10A
1+1 Redundancy up to 10A requires two 10A power supplies and one YRM2.DIODE redundancy module.
