Power supplies & Voters – SS855

The SS855 is a voting unit for building redundant power supply systems. It is equipped with two input channels and one output. The two inputs are decoupled by MOSFET technology.

SS855 can be used directly for loads up to 20 A (two 20 A power supplies and one SS855).

With dual SS855 it is possible to vote redundant 40 A (two 40 A power supplies and two SS855). The inputs are located at the bottom of the SS855 and the output is located at the top of SS855. SS855 does not have any power OK signals, instead use power OK signals on SD834, SD853, or SD854.
