Select the type of equipment to medical or build a good power supply system, care must be taken to improve the supply of electromagnetic compatibility and immunity to 12v inverter electromagnetic interference. Mainly from the following aspects to consider: design. PCB design and layout, in general will contain some high-frequency power signal to any of the tracks on the PCB can serve as an antenna, the length and width of the printed lines will affect the resistance and inductance, thus affecting the frequency respond in a timely manner is also coupled to the radio frequency signal circuit and cause problems by printing wire DC signals from adjacent tracks. Therefore, the power supply must be Solar power inverters selected medical class brands, with strong R & D strength of the company's products, which in the design and production processes can ensure good quality.
