Description
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.
