Selection method of switching power supply

1, when buying a switching power supply, you should first observe the shell material of the switching power supply. At present, the shell of switching power supply in the market generally adopts pc material, which has good high temperature resistance and impact resistance and is not easy to change color during use, but the base of some inferior switches is replaced by nylon material, which reduces the production cost.

2. Then look at the contacts of the switching power supply. Generally, it depends on the size and material of the contact. The larger the contact area, the better. As for the contact materials, at present, pure silver, silver cadmium alloy and silver nickel alloy are the main materials, among which silver nickel alloy has the best use effect, good hardness and conductivity, and is not easy to rust.

3. Look at the connection mode of switching power supply, many users will ignore this when purchasing, but the connection mode directly affects the safety of electricity consumption. At present, the connection mode of switching power supply is mostly plug-in card connection mode, but the price is too expensive, so ordinary families can use ordinary double-hole pressure plate structure.

4. Before buying the switching power supply, please specify the input voltage range. For example, the common AC voltage specifications are 1 10V and 220V, so we should choose 1 10V and 220V AC switching power supplies. The general input voltage is AC: 85V-264V, and this specification can also be selected. Choose the voltage specification according to the use environment when purchasing.

5. Because the switching power supply will generate heat due to power consumption when working, attention should be paid to the heat dissipation of the switching power supply. Switching power supply has poor heat dissipation, easy damage and short service life.

Life is inseparable from the power switch. When choosing a switch, you need to know something about its brand. These are the brands and purchase methods of switching power supply introduced by Bian Xiao, and they are here.
