Description
In this protection state, the power module stops supplying
power. When the input voltage restores to the normal range,
the power module automatically resumes power supply.
In this protection state, the power module stops supplying
power and cannot automatically resume power supply when
the input current restores to the normal range.
In this protection state, the power module stops supplying
power intermittently. When the system recovers from output
overvoltage, the power module automatically resumes power
supply.
In this protection state, the power module supplies power
intermittently. When the output current is within a range, the
power module automatically resumes power supply.
In this protection state, the power module supplies power
intermittently. When the short circuit is removed, the power
module automatically resumes power supply.
When the temperature of the power module exceeds a
specified threshold, the power module stops supplying
power. When the temperature falls into the normal range, the
power module automatically resumes power supply.
