Description
Short circuit fault occurred at the output of the
power supply. This is triggered when the load
current is greater than 150% of the rated load.
The output voltage of the power supply is greater
than 32V for SDN10 and 35V for SDN20.
Internal temperature of the power supply
exceeding safe operating levels. This occurs when
the main transformer temperature
exceeds 125°C.
