Short Circuit

The Protection Such as Hiccup, and Can Rework after Remove the Fault

Fan malfunction

When the single fan fails, the module automatically drops 50% power to run and alarm, until the module over temperature protection turns off the output. When two fans fail at the same time, the module issues a warning and closes the output directly.
