Protection requirements
Overcurrent protection	Overcurrent protection point limit:105%~150% full load (115~230Vac) When overcurrent acts on the output, the output will hiccup and will automatically recover when the fault condition is removed.
Short circuit protection	When the output is short-circuited, the input power should be reduced. The power supply should not be damaged and should automatically recover when the fault is removed.
