To obtain higher output voltage of 48 V, with 100 % redundance, it is possible to connect two modules in series plus two redundant modules in parallel as shown in the figure.
Output voltage can be furtherly increased maintaining redundancy by paralleling more units in series.
NOTE: In this configuration, Current Sharing feature is not available, therefore current sharing connection (CS) must not be used.
