Redundant power supply
One or two power supplies can be used in the SWT 3000 system. Decoupling is provided by
means of diodes on the rear PC board. The output voltages from PS-1 and PS-2 are monitored by
the PU3f module in order to detect failure of a power supply unit.
The interface modules IFC are supplied via the PU3f.
