Many friends do not know why the module power supply shell will be charged? Will it hurt people? What is the reason? Let's tell you the specific reasons: In the module power supply housing, the center of the module filter capacitor is suitable for the housing linked together. The housing is suitable for the ground wire connected together in the unidirectional three-wire system. At this time, the capacitor will produce a certain impedance value, Therefore, the housing will have a certain potential, if there is no installation of the ground wire, in wet weather contact the housing will have an obvious motor feeling.
