Precautions
1.Select the appropriate power rating to extend the power supply lifespan. Please choose a product with a rated output power 30% higher than that of the electrical appliance. For example, for an appliance with 80% power, select a power supply with 100% power.
2.Due to the high working efficiency of switching power supplies, which can generally reach over 80%, when selecting the output current, you should accurately measure or calculate the maximum absorbed current of the electrical equipment.
3.Before powering on, check if the input and output leads are connected correctly to avoid damaging the equipment.
4.Power supplies with multiple outputs are generally divided into main and auxiliary outputs. The main output has better characteristics than the auxiliary output, and generally the one with a larger output current is the main output.
5.The power supply must not be installed in environments with flammable materials or where fire is likely to occur (such as wood products, plastics, cardboard, and other flammable items) to prevent fires.
