Protective Characteristic |
||||||
|
Over and Under Voltage Protection |
Input over and under voltage shutdown can be self-recovery, output over and under voltage shutdown can be self-recovery. |
|||||
|
Output Reverse Connection and Short Circuit Protection |
Output short circuit and reverse connection shutdown can be self-recovery |
|||||
|
Over Temperature Protection |
When the heat sink temperature is higher than 75 ° C, it will reduce the output power. And it will disconnect the circuit when the temperature is higher than 95 ° C. It will restore the output when the charging temperature is lower than 85 ° C. |
