In addition to itself, whether medical equipment can work efficiently or not is also related to the power source. The quality of the power supply directly affects the stability and reliability of the device. Poor quality can even lead to medical accidents and economic losses. The most commonly used are built-in power supplies that output various voltages through an integrated converter. The integrated type has so many advantages as low cost, high efficiency, adaptive voltage output, low noise and dynamic response. When choosing a power plan, you should consider some problems, such as security, isolation, compatibility, and protection from interference.
Safety and isolation are the two main characteristics of a medical power supply that make it different from a power supply for a business. Most of the medical equipment is installed next to the patient and operator; therefore, their shells are easy to touch. Problems with the shell will be very dangerous.
Compatibility and anti-interference of the power source should be considered in many aspects, such as design, screen, certification, specific application and price. First, the medical power supply must select a well-known brand product that can provide quality design and crafts. Secondly, to control the radiation emitted by the power source, it is best to protect the magnetic field. Third, most medical equipment must pass compatibility and anti-withdrawal tests, such as FCC-B and CISPR22-B. Tested devices do not affect other electrical components. Fourth, most integrated power supplies have a standard output, although some of them can adapt the output power by connecting an external circuit. The adaptation range is small and the output power is not stable enough. Fifth, competition in the medical equipment market is becoming fierce in our day, especially the home device. Being an important component of the device, the price of the power supply must be competitive. Related integrated circuit - KA7808.
