Choose the right power in order to increase the life of the power supply. Please choose a model with 30% more output power rating than the electrical appliance. For example, 80W electrical appliances, please use 100W power supply. 3. In addition, the working environment temperature of the power supply needs to be considered, and whether there is additional auxiliary heat dissipation equipment, and the output of the power supply with excessively high ambient temperature needs to be derated. 4. Due to the high efficiency of the switching power supply, which can generally reach more than 80%, in the selection of its output current, the maximum absorption current of the electrical equipment should be accurately measured or calculated. 5. Before turning on the power, check whether the input and output leads are connected correctly to avoid damaging the user's equipment. 6. Check whether the installation is firm, whether the mounting screws are in contact with the power supply board components, and measure the insulation resistance between the casing and the input and output to avoid electric shock. 7. To ensure the safety of use and reduce interference, please ensure that the grounding terminal is reliably grounded. 8. Multi output power supplies are generally divided into main output and auxiliary output. The main output characteristic is better than the auxiliary output. In general, the main output is the main output with large output current. In order to ensure the output load adjustment rate and output dynamics and other indicators, generally required that each channel carry at least 10% load. 9. Please Note: Frequent switching of the power supply and the working environment and the load range will affect life. You can choose a model with 30% more output power rating. 10. The power supply must not be installed in an environment with flammable materials and easy to catch fire (such as wood products, plastics, cardboard and other easy to burn materials) to prevent fire..
