14 Volt Power Supply
ac dc adapter 6v is to cut the DC voltage obtained after rectifying the commercial power into a rectangular wave (of course, the actual waveform is not a perfect rectangular wave, but there will be overshoot). The significance of doing this is to cut the high energy into countless low energy and transfer it to the output end, which will pass the output voltage, Feedback to the input (adjust the cutting frequency and the width of the cutting duty cycle) to achieve the purpose of stabilizing the output voltage
Description
Description
AC DC switching adapter is a kind of power supply which uses modern power electronic technology to control the time ratio of switching on and off to maintain stable output voltage. The switching power supply is generally composed of pulse width modulation (PWM) control IC and MOSFET. With the development and innovation of power electronic technology, the switching power supply technology is also in constant innovation. At present, switching power supply is widely used in almost all electronic equipment with the characteristics of small size, light weight and high efficiency. It is an indispensable adapter 12vdc 2a for the rapid development of electronic information industry.

Application of 14 Volt Power Supply in several aspects
1. Electric power, mainly including integrators, meters and smart meters
2. Industrial control, industrial control field
3. Medical treatment, medical equipment, mainly including fetal care instrument, monitor, etc
4. Military industry, military industry is a widely used aspect. Military equipment.
The high frequency transformer of 230v to 5v adapter is usually shielded for the first time. Switching power supply is a high frequency product. Please pay close attention to the layout of PCB components for EMI.
If the ac dc adapter 28v has a mechanical shell, the structure of the shell has a great impact on the radiation, please pay close attention to this point. The parameters of main switch tube and main diode from different manufacturers are different, which has certain influence on EMC. Please pay close attention to this point.
