Safety Standards
Design Features
Built-in Protection Functions
Overload Protection
Overload protection operates at approximately 105%–135% of rated output power. The output is limited or cut off during an abnormal overload condition and automatically recovers after the fault condition is removed.
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.
