Package List: 1 x Power Converter1 x Wiring Drawing Note: 1. In order to ensure the normal operation of the converter within the input voltage range, the input voltage must not be lower than the minimum or maximum input value restricted by the product during use, and the input voltage value must be higher than the output voltage value by more than 2V. If there is no 2V voltage difference, the output value will be lower, but it will not damage (affect) use of the converter.2. The input current must be greater than or equal to the power required by the output load device (for example, if the power of the load device needs 100W, then the input power must be greater than or equal to 100W). When the converter is in use, the current of the load device should not be greater than the maximum current value that the converter can withstand, and leave as much margin as possible for the converter to ensure that the converter works normally and achieves the highest conversion efficiency.3. The positive and negative poles of the converter cannot be reversely connected during use. Reverse connection may cause damage to the converter. It is recommended to add a suitable fuse to the input terminal during use.4. The chip works in light load mode when there is no load, and the output voltage may vary within a certain range.
