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 recovers after the abnormal load condition is removed.
Short Circuit Protection
Built-in short-circuit protection helps protect the power supply during abnormal output conditions. Normal operation can resume after the fault condition is removed.
