Precautions
1.Select the appropriate power. To prolong the service life of the power supply, please choose a product with an output power rating 30% higher than that of the electrical appliance. For example, for an 80W electrical appliance, select a 100W power supply.
2.Since the switching power supply has high working efficiency (generally reaching more than 80%), when selecting the output current, the maximum current absorbed by the electrical equipment should be accurately measured or calculated. Generally, the one with a larger output current is the main output.
3.Before energizing, check whether the input and output leads are connected correctly to avoid damaging the equipment.
4.Multi - output power supplies are generally divided into main and auxiliary outputs. The characteristics of the main output are better than those of the auxiliary output. Generally, the one with a larger output current is the main output.
5.The power supply shall not be installed in an environment with flammable materials and materials that are easy to catch fire (such as wood products, plastics, cardboard and other flammable items) to prevent fire and fire accidents.
