XVC768101 3BHB007211R101 电源模块电源模块的作用就是电压的转换，它可以将交流或直流电变换成你所需要的交流或直流电。如:将市电220V交流电(AC)转换成5V直流电(DC),因为交流220V的电是高压电，而电子产品是低压供电的，这就需要一个转换装置， 将交流220V的电压转换成低压。 再比如在机动车理有时需要转换成220V交流电来使用，那么这会就成了低压转高压了，因为机动车的电压-般都比较低。简而言之就是类似手机充电器-样,你的手机没电了，要插电或充电才能正常使用，但是你不能直接接220V使用，因为这样手机就会烧毁，因此就需要一个专门的转换装置来转换成手机所需的电压。
The function of the power module is to convert voltage, which can convert AC or DC power into the AC or DC power you need. For example, converting 220V AC from mains power to 5V DC, as 220V AC is high-voltage and electronic products are low-voltage powered, requires a conversion device to convert 220V AC voltage into low-voltage. For example, in motor vehicle management, sometimes it is necessary to convert to 220V AC for use, which becomes a low voltage to high voltage conversion because the voltage of motor vehicles is generally relatively low. In short, it is similar to a mobile phone charger. Your phone runs out of battery and needs to be plugged in or charged to function properly. However, you cannot directly connect it to 220V, as this will cause the phone to burn out. Therefore, a specialized conversion device is needed to convert it to the voltage required for the phone.
