 Performance features:

1 low voltage protection function: when the battery voltage is lower than the specified value, close the output, a good protection of the battery, effectively prevent the battery over discharge.

2 short circuit protection function: when the output is short circuit, the converter automatically shut down the output, automatically restored after the short circuit point .

3 over voltage protection function: when the output voltage exceeds the specified nominal voltage, the converter is closed and the output is guaranteed,  ensure that the back-end electrical appliances are not burned..
