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. 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 15).
