■Overcurrent protection: When the output current is greater than the set value, the output voltage value gradually decreases until there is no voltage output. (When the starting load is too large, it will start overcurrent protection, no output voltage, some common inductive loads, such as motors, pumps, etc.)

■Overtemperature protection: When the chip temperature is greater than 150 ° C, the power converter stops working and there is no voltage output. (Note: This temperature does not refer to the working ambient temperature)

■Short circuit protection: Under normal use, the output straight negative pole is shorted instantaneously, which will not cause damage to the power converter. (Note: This protection includes all step-down products, step-down products and isolation products;  The booster product line does not carry this protection.)

■Input reverse protection: the positive and negative input terminals are reversed, which will not cause damage to the power converter. (Note: Some products have this protection function.)

■Waterproof protection: All power converters are designed with waterproof potting technology (waterproof, dustproof, shock-proof).

■Low voltage protection: When the input voltage is lower than the set value, the output voltage value gradually decreases until there is no voltage output. (Note: Low-voltage protection can effectively extend the service life of the battery and prevent the overdischarge of the battery .)
