3.6.2.1 Functions
The function of the CAN-PSF-MSC is to convert single-phase AC main
voltage into multiple DC voltages. This powers the other modules in the
MSC-L and also provides DC power to external devices such as flow
meters, temperature sensors, and so on.
On the system level two separate Power Supply Units (PSUs) operate
the sharing current. The two PSUs make the system powering
redundant. One PSU is able to power the complete system at maximum
temperature. See FIGURE 3-22 for the functions of the MSC-L.
