Brief Introduction of Power Supply Products
The regulation of power supply (power adapter) usually meets the requirements of safety and electromagnetic compatibility (EMC). Among them, the safety specification is more complex. Electromagnetic compatibility (EMC) will cause more trouble only when switched power supply is used, while traditional linear power supply seldom has EMC problems. When power supply is supplied to different products, the legal standards that power supply should meet are also different. In principle, the legal standards that power supply should meet are determined by which products it should cooperate with.
