Application Notes
19.1
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.
19.2
Inductive and Capacitive Loads
The unit is designed to supply any kind of loads, including unlimited capacitive
and inductive loads.
19.3
Sideward Installation Clearances
The minimum clearance recommendations are defined in chapter 4.
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).
Figure 19.1
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 PS1000 series.
•
The redundancy module is placed between the two power supplies.
•
The output voltage is set to the same level on both power supplies.
