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)
(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.
