PROTECTION

Built-in Protection Functions

Overload Protection

Protection operates at approximately 105%–130% of rated output power. Constant current limiting protection is used and the power supply automatically recovers after the abnormal load condition is removed.

Overvoltage Protection

Overvoltage protection turns off the output voltage. Protection levels are 14–17V for the 12V model, 29–33V for the 24V model and 56–65V for the 48V model. Recovery is achieved after restarting the power supply.

Over Temperature Protection

The output is shut down when the over-temperature protection is activated. Recovery is achieved after restarting the power supply.
