17. APPLICATION NOTES
YR40.482
24-56V, 40A, DUAL REDUNDANCY MODULE
17.1. 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.
17.2. INDUCTIVE AND CAPACITIVE LOADS
The unit is designed to supply any kind of loads, including unlimited capacitive and inductive loads.
17.3. SIDEWARDS INSTALLATION CLEARANCES
The minimum clearance recommendations are defined in chapter 2.
Normally, the following installation clearance are recommended: 40mm on top, 20mm on the bottom, 5mm on the
left and right sides when the device is loaded permanently with more than 50% of the rated power. Increase this
clearance to 15mm in case the adjacent device is a heat source (e.g. another power supply).
The clearance between the power supplies and the redundancy module can be reduced to zero under the following
conditions:
- 1+1 redundancy application with maximum 20A

output current.
- The power supplies are from the PULS DIMENSION
series.
- The redundancy module is placed between the two
power supplies.
- The output voltage is set to the same level on both
power supplies.
