switching power supply
1. Choose the appropriate voltage range
Common sense tells us that the household voltage is 220V, so if the switch is used at home, a switching power supply in the 220V range should be selected. For other jobs that have special requirements, you must purchase them according to the requirements. On the market, there are not only 220V but also 110v voltages, and most of the common 220V types are available.
2. Power selection
When choosing a switching power supply, power also needs to be taken into consideration, because the power switch is an electrical appliance, so it will lose power, and the rated power is larger than the actual power. For example, if you want a 220V1500W power switch, you actually choose The power switch should be greater than 220V1500W.
switching power supply
If the selected power is 1500W, the power switch will be damaged when the power of the electrical appliance used is greater than that of the power switch. Because it cannot withstand high power, it is better to go big than small.
3. Cooling assistance
Because the power switch will generate heat during operation, a heat dissipation device is required to dissipate the heat generated by the power switch. If there is no heat dissipation device, excessive temperature will cause a fire hazard. Therefore, when purchasing a power switch, you must choose a heat dissipation device. device switch.
