Specification: Item Type: DC Buck Converter Material: Die Cast Aluminum, Epoxy Resin Input Voltage: 12V 24V (8-40V) Output Current: 20A Conversion Efficiency: 96% Output Voltage: 5V Output Power: 100W Operating Temperature: -20℃ to 80℃ Protection Grade: IP67. Package List: 1 x DC Buck Converter Note: 1. To ensure the proper operation of the converter within the input voltage range, the input voltage should not be lower than the minimum or maximum input value specified by the product. The input voltage must be at least 2V higher than the output voltage. If there is no 2V voltage difference, the output value may decrease but it will not damage the converter. 2. The input current must be greater than or equal to the power required by the output load device (e.g., if the power required by the load device is 100W, then the input power must be greater than or equal to 100W). During the use of the converter, the current of the load device should not exceed the maximum current that the converter can withstand. It is recommended to leave some margin to ensure the normal operation and achieve the highest conversion efficiency of the converter. 3. The positive and negative terminals of the converter must not be reversed during use, as this may cause damage to the converter. It is recommended to add appropriate fuse protection at the input end. 4. When there is no load, the chip operates in light load mode, and the output voltage may vary within a certain range.
