Description
In this protection state, the power adapter stops supplying power and
cannot automatically resume power supply when the input current
restores to the normal range.
In this protection state, the power adapter supplies power
intermittently. When the output current is limited within a range, the
power adapter automatically resumes power supply.
In this protection state, the power adapter stops supplying power
intermittently. When the output voltage restores to the normal range,
the power adapter automatically resumes power supply.
In this protection state, the power adapter supplies power
intermittently. When the short circuit is removed, the power adapter
automatically resumes power supply.
The power adapter does not have built-in fans and uses nature heat
