17、Over Current Protection 过电流保护
When an internal fault occurs, or an
external fault is applied to the adapter,
such that an overload or short circuit is
applied to the output, the adapter shall shut
down. It will enter into normal condition if
the fault condition is removed.
Shutdown and no damage.
当发生内部故障，外部故障或应用到适配器，这样一过载或短路应用到输出，该适配器将关闭。如果故障排除。将进入正常状态，
18、 Over-Voltage Protection过电压保护
The adapter will enter into shut down that
means no output while over voltage
happened at output terminal that caused by
internal fault, the output trip voltage shall
not exceed 32 volts with a maximum
duration of 250 milliseconds. That will be
return to normal state by AC reset.
Shutdown and no damage
. 该适配器将成为关闭这意味着没有进入过电压，而输出端，通过内部发生故障所造成的输出，输出电压不得超过行程为250毫秒的最长期限32伏特。这将返回交流reset.Shutdown并没有损害到正常状态。
19、 Over Temperature Protection The adapter have thermal protection for
abnormal usage for/by parts failure. This
protection shall operate before rising to
reach to the cover-case’s deformation and
discoloration temperature.
The adapter shall be shut down and enter
latch-off mode. That will be return to
normal state by AC reset.
No broken, no smoke
过温保护的适配器有/零件故障异常使用的热防护。这种保护应上升到日前运作达到盖的变形和变色温度下适配器将被关闭，进入
闭锁模式。这将返回到正常状态交流。不能撞击，不能投入火中
