PROTECTION

Built-in Protection Functions

Overload Protection

Protection range is approximately 110%–150% of rated output power. Hiccup-mode protection is used. The power supply automatically recovers after the abnormal load condition is removed.

Overvoltage Protection

The overvoltage protection level depends on the selected output model. Protection turns off the output voltage and recovery is achieved after restart. The individual voltage ranges are shown in the model table above.
