What is smart auto-disconnect protection?何謂智慧斷電保護呢?

Updated: Sep 9, 2019

Once the product is connected to a power source, current begins to flow and the product is activated. When load is encountered during operation, the built-in mechanism will automatically cut off the power to protect the product as well as the user.

當產品接上電源,通過電流,啟動運作並遇到負載情況,為了保護產品,內建的機制會產生自動斷電的行為,同時也保障消費者的安全


Behaviors that cause auto-disconnect 

In most cases, the reason for cutting off the power supply can be attributed to one of the following five causes:

產生自動斷電的行為

停止供電的原因,可以大致區分為下列五項標準:


1.Short Circuit Protection 

Determining if a short circuit has occurred by detecting the difference before and after outputting voltage.

短路保護

經由輸出電壓前後變化來判定是否發生短路行為

2.Overload Protection 

After connecting the product to a power source, the rated power load is too great, which results in the activation of the auto-disconnect protection.

過載保護

在連接電源的產品中,因額定功率負載過大而產生自動斷電的功能

3.Overcurrent Protection

When the current passing through has exceeded the maximum value set for the product, auto-disconnect protection will be activated.

過電流保護

當通過的電流超過產品預設的最大值時,便會產生斷電保護

4.Overvoltage Protection 

When the product detects a voltage that is too high, the voltage will be dropped immediately to prevent damaging the connected device.

過電壓保護

當產品偵測到電壓過高時,會迅速的將電壓拉下來,避免傷到接上的裝置

5.Overheat Protection 

During product use, if the internal temperature has reached the upper limit, the connection will be cut off automatically. This is a safety mechanism to prevent product overheating.

過熱保護

當產品因為使用而造成內部電路溫度升高到達限制時,便會切斷接點。是防止產品過熱而燒毀的安全機制。


Many products available on the market today are equipped with the five features listed above, which can be used as the basis for selling or purchasing a product. After all, more protection will provide more safety. Please remember to always choose carefully when you purchase an electronic product.

現在市售的很多產品都一定具備上述五項特點,可以做為販售或購買時的依據,畢竟多一分安全多一分保障,帶電的產品一定要仔細慎選喔
