Built-in Protection Functions
Overload Protection
Protection operates at approximately 105%–150% of rated output power. Output power limiting protection is used and the power supply automatically restores operation after the abnormal condition is removed.
Overvoltage Protection
Overvoltage protection is specified at approximately 115%–135% of the rated output voltage.
Short Circuit Protection
Built-in short-circuit protection helps protect the power supply under abnormal output conditions. Normal operation can resume after the fault condition is removed.
