Over current protection: when the output current is higher than the set value, the output voltage gradually decreases until there is no output voltage.
Over temperature protection: When the case temperature is ≥ 85 ℃, the power converter stops working, and there is no voltage output.
Low voltage protection: When the input voltage is lower than the set value, the output voltage gradually decreases until there is no output voltage.
