Power converter, also known as AC converter, is a type of transformer. Due to the different power environments and civilian voltages in various countries and regions around the world, the voltage range of electrical appliances in different countries is also different. Common types are 220V voltage and 110V voltage. Power converter is a scientific name, also known as patch panel, also known as patch panel, patch panel, or wiring board, and in Hong Kong, it is called drag line board. Pick up the patch panel we usually use, which not only has the product name of the power converter printed on it, but also some electrical parameters, such as maximum voltage, maximum current, frequency, etc. When using power converters, everyone should follow these parameters. Improper use, especially when using low-quality power converters, can lead to unsafe accidents such as electric shock and fire
