Two buffer modules can be paralleled to build a 1+1 redundant system to gain higher system reliability. 
Recommendations for building redundant power systems: 
a) 
Use separate input fuses for each power supply. 
b) 
Set the power supply into “Parallel use” mode if available. 
c) 
Use a redundancy module to decouple the two power sources. 
d) 
Monitor the individual sources. Therefore, use the alarm contacts of the YRM2.DIODE redundancy module. 
(The YRM2.DIODE is suitable for a 10A redundant system) 
e) 
It is desirable to set the output voltages of all power supplies to the same value (± 100mV) or leave it at the 
factory setting.

Buffer modules can be paralleled to extend the buffer time.
