SP/P – Power supply module
Power supply module SP/P is a part of SANPO complex, designed in Russia.
SP/P power supply module provides control and redundancy of SANPO supply circuits.
To achieve a high redundancy level, it is possible to connect two SP/P modules to SP/RACK crate, and one or two independent external power supplies «+24V» can be connected to SP/P module.
When SP/P module is redundant itself in one crate and, as a result, four external power supply sources are applied, there is triple redundancy of SANPO external power supply circuits (one is in operation, three are redundant) and double redundancy of power supply circuits of every system module. One of SP/P modules in this case is constantly redundant.
SP/P module has an independent diagnostics channel with SP/A module and SP/P module makes simplex transmission of reports about power supply circuits condition as well as its own condition.
SP/P module is suitable for a «hot swap».
