Notes:Output Load Requirements for HLk-F1224S-1WR3 Dc-Dc Power Module

In order to ensure that the HLk-F1224S-1WR3 Dc-Dc Power Module can work efficiently and reliably, the minimum output load should not be less than 10% of the rated load.If the power you need is really small, please connect a resistor in parallel between the positive and negative poles of the output terminal (the sum of the actual power used by the resistor is greater than or equal to 10% of the rated power and the rated power of the selected resistor must be greater than 5 times of the actual power used, otherwise the temperature of the resistor will be higher)
