Redundant PS Unit
The RPSU-BSDU-1 is a redundant PS Unit for the BSDU AC/DC power converter. The power factor
corrected (PFC) front ends provide a 48 VDC output for distributed power applications. The small 1U
by 2U size allows for configurations of either height in hot-swap redundant systems while its
internal fan and cooling design permits wide use with reliable operation.
