Under normal trial, the converter output is momentarily shorted to ground without causing damage to the power converter. Output load current is too , the power supply module is not damaged. Reduce the damage rate of power supply. Abnormal output voltage of the power supply is higher than the set value, the protection works to protect the load electrical appliances from damage. Converter working environment temperature can be -40 to 85 , when the shell temperature exceeds 85 , the converter is automatically protected.
