The voltage will fluctuates in the vicinity of the protection value, it will recover automatically
after fault condition is removed
No output when exceeds temperature protection point, it will recover automatically after the
temperature falls below the threshold value
In hiccup mode, it will recover automatically after fault condition is removed
