Medical switching power supply and ordinary switching power supply difference in which

First: Because medical products may be directly on the human body, so the medical switching power supply insulation and leakage requirements are higher, which is the biggest difference between the medical power supply and ordinary power supply. At present, medical switching power supply must meet the IEC60601-1:2005 (third edition) safety standards. Second: medical power supply on electromagnetic radiation and electromagnetic radiation protection have higher requirements (EMC), the power supply itself can not cause interference to nearby equipment, nearby equipment can not interfere with the power supply itself. After all, it is used in the human body on the device, if the electrocardiogram because of interference with clutter, it is likely to cause the doctor's misjudgment. Third: in fact, the medical power supply is also divided into home and hospital use, international standards require medical equipment for home use must be Class II level, in layman's terms is the AC input is a two-hole, not with a grounding wire 3-hole. The opposite is true for hospitals, which use 3-hole sockets with grounding. You need to be aware of this when designing and selling medical power supplies.
