7.1 OVERVOLTAGE PROTECTION
The AC-DC power supply provides a fixed threshold
overvoltage (OV) protection implemented with a HW
comparator. Once an OV condition has been triggered, the
supply will shut down and latch the fault condition. The
latch can be unlocked by disconnecting the supply from the
AC mains only.
7.2 CURRENT LIMITATION
The main output current limitation will decrease with linear
derating to 50% at 70 ºC if the ambient (inlet) temperature
increases beyond 50 °C (see Figure 13).
