Because for the current industry market, inferior power adapters account for about 30% of the market. It is a big threat to those of us who make high-quality products, because the unit price of power adapters produced with second-hand originals will be 30% or more lower than the unit price of our brand-new materials. As a result of the current market confusion, some manufacturers compete for price, and quality has not received much attention. For customers, it is a big hidden danger for end consumers. computer power adapter
1. Overvoltage protection to prevent excessive voltage;
2. Overcurrent protection, automatic protection when the current is too large;
3. Abnormal temperature protection to prevent the temperature from being too high;
4. Over-power protection to prevent power overload;
5. Lightning strike protection to prevent damage caused by lightning strikes;
6. Electromagnetic field protection, free from external electromagnetic influence;
7. Short circuit protection
8. Electrostatic protection
In order to make the laptop work stably, a stable DC voltage must be provided. This device that provides a stable DC voltage is a DC stabilized power adapter. This DC regulated power adapter, in addition to providing a stable DC power adapter for the electronic circuit of the notebook computer, also has high reliability, safety and environmental resistance. computer power adapter
First, it can enhance the design of the input/output filter circuit, improve the performance of the active power factor compensation (APFC) circuit, reduce the voltage and current rate of change of the switching tube, rectifier and freewheeling diode, and use various soft switching circuit topologies. Structure and control methods, etc.; on the other hand, strengthen the shielding effect of the casing, improve the gap leakage of the casing, and perform good grounding treatment.
