  How to choose the power adapter?(图1)

  1. In order to improve the reliability of the system, it is recommended that the power adapter work at 50%-80% load, that is, assuming that the power used is 20W, a power adapter with an output power of 25W-40W should be selected.

  2. Try to use the manufacturer's standard power supply, including standard size and output voltage. In this way, delivery will be faster; special standards and output voltages will increase development time and cost.

  3. Clarify the input voltage plan. Take AC input as an example. The commonly used input voltage standards are 110V and 220V, so there are three standards for 110V and 220V communication switching, and universal input voltage (AC: 85V-264V). The input voltage standard should be selected according to the application area.

  4. The power adapter consumes part of the power during operation and releases it in the form of heat. Therefore, the user should consider the heat dissipation problem of the power adapter in the system design (especially a closed system).

  5. Determine the required output voltage and current according to the usage conditions; power supply size, installation method and installation hole position; there are several outputs, whether each output requires electrical isolation; input voltage planning; decide on the power adapter according to the ambient temperature The degree of derating, the power of the power supply; whether certification and safety standards are required; the cooling method of the power supply: natural cooling or forced air cooling; electromagnetic compatibility standards.
