NGPS – User’s Manual
30
The threshold value [°C] can be modified by experienced users. A reset fault
operation needs to be executed on the status register of the NGPS before turning the
output on again.
DC-Link Undervoltage
The NGPS is internally composed by a power AC-DC section cascaded with a
DC-DC stage. The DC voltage generated by the AC-DC section is also called DC-Link
and it is proportional to the maximum rated voltage of the specific model.
A continuous monitoring of the DC-Link voltage is performed in order to
always guarantee the capability of obtaining the maximum voltage from the power
supply. If the DC-Link drops below a certain threshold, the power supply unit could not
be able to correctly regulate its output anymore, so that a fault condition is generated.
It is necessary both to reset the status register and to get rid of the fault cause
before turning on the power supply again.
