Built-in Protection Functions
Overload Protection
Protection operates at approximately 105%–135% of rated output power. Output power limiting protection is used and normal operation automatically recovers after the abnormal load condition is removed.
Overvoltage Protection
Built-in overvoltage protection is provided for each S-400 output version. The protection threshold depends on the selected output voltage model.
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.
