Built-in Protection Functions

Overload Protection

Protection operates at approximately 105%–150% of rated output power. Fold-back current limiting 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 automatically resumes after the fault condition is removed.
