The domestic medical equipment they use 220V mains supply. Since various types of medical equipment power requirements, the most used is the centralized power structure. That is, Car power inverters from a centralized power converter to generate the required output voltages of various voltage levels. Because of its low cost, high efficiency, the output voltage is adjustable, low output noise, fast dynamic response, such as type of equipment is very suitable for medical use, medical devices are currently the most used kind of a power supply. Medical equipment supply program to determine the need to consider the following questions.
Security and isolation is a major difference between ordinary commercial power supply and medical supply. Typically, in addition to some experimental analysis class equipment, medical equipment, mostly installed in the vicinity of the bed or operating table, and the operator's relatively close distance from the shell will often be touched. There are a wide variety of medical equipment inside the strong, weak components, if the strength of electrical isolation between the shell material or insulation problem, it will be very dangerous. General safety testing of medical equipment power supplies must be UL60601-1, C-UL, EN60601-1 safety certification. Inputs and outputs must be more than 4,000 V isolation voltage, and low leakage current requirements, compliance with safety regulations creepage distance requirements. And part of the 12v inverter need for strong electric double insulation, especially some of them might be more in contact with the equipment enclosure designed to enhance insulation.
