12V2A power adapter (power adapter) is a small portable power supply conversion equipment for electronic equipment and electronic appliances. It is generally composed of shell, transformer, inductor, capacitor, control IC, PCB and other components. Its working principle is from AC input to DC output; According to the connection mode can be divided into wall and desktop.

12V2A power adapter is widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifier, electronic refrigerator, LCD, LED lamps, communication equipment, audio-visual products, security, computer chassis, Digital products and instruments.

It creates a good heat dissipation environment for the work of 12V2A power adapter. When using 12V2A power adapter in high temperature environment, the 12v2a power adapter should be placed in a well ventilated place away from direct sunlight; Do not place the 12V2A power adapter near the heat outlet of the heat source, otherwise not only the heat of the 12v2a power adapter cannot be emitted, but also part of the heat will be absorbed.

If 12V2A power adapter is abnormal, it should be stopped in time. When the 12v2a power adapter makes a big noise or even smoke, it is often damaged or has a fault, so it should be stopped immediately, and it can be put into use again after maintenance by professional engineers.

Be careful when using non original power adapter. There may be some differences in the output interface, voltage and current value of the non original power adapter (or the nominal value is inconsistent with the actual value). If it is not matched properly, it may affect the stability of the electrical operation, or even more serious consequences. Be sure to use the regular brand 12V2A power adapter.
