Nowadays, domestic science and technology is developing very fast, and various new electronic equipment and electronic appliances are emerging in an endless stream. Various accessories related to this are constantly updated to ensure that the various performances of the products are more outstanding. Today we are talking about power adapters. It is an indispensable accessory in electronic equipment and electronic appliances. It can be said to be a voltage conversion device. Any product or equipment, no matter how good its quality and performance is, will have the possibility of failure. There is no doubt about this. I don't know if you understand the common failures and troubleshooting methods of power adapters?
If the power cord of the power adapter is damaged, it is not energized, or the contact is oxidized and the contact is poor. At this time, you need to check whether the input line and output line are energized. If the line is faulty, replace the power line in time.
Some power adapters will have low output voltage. What causes it? The load of the switching power supply is short-circuited. At this time, all loads of the switching power supply circuit must be disconnected. If the voltage output is normal after the load circuit is disconnected by the ground, it means that the load is too heavy. If it is still abnormal, it means that it is a switching power supply. The circuit is faulty. The 300-volt filter capacitor is poor, resulting in poor load carrying capacity of the power supply, and the output voltage will drop as soon as the load is connected.
If the output voltage of the power adapter is too high, you need to check it carefully. Any problem with any part will cause the output voltage to rise. Which part has a problem should be replaced in time. The power adapter will also have the problem of fuse burnout. At this time, you need to check the diodes, the rectifier bridge, the large filter capacitor on 300 volts, and the switch tube. Of course, it may also be caused by a problem with the anti-interference circuit, which caused the fuse to burn out.
Now that the market competitiveness is so fierce, many manufacturers are constantly improving the quality and performance of power adapters in order to occupy more sales markets, so that they can have higher sales. For production companies, if they want to have a longer-term development, they need to strictly control product quality. Xinjukang Technology has introduced a number of advanced production and testing equipment, just to provide customers with better quality power adapters. Products move the market, and services move customers.
