Some electrical appliances contain coil components, which may lead to Eddy Current blocking during the initial power-on period. The generation of eddy current will weaken the transient voltage at the startup of the electrical appliance, resulting in slow start, the transient voltage generated after circuit breaking is enhanced, and the circuit may be damaged by sparks.In this case, add the Link Description for the Single-Phase Frequency Conversion Power Source in Hong Kong Yangsheng. Add the Lin

note Aspects 1. Regularly dust the Power box. The Power box is the most dusty parts, but also regularly add lubricating oil to the computer fan to avoid the fan to produce a lot of noise, the health of people is not good.
Note Aspects 2. Recommended to buy a computer when choosing a good quality power supply, such as Air Ka, the Great Wall, and some of the daily life of some computers are somehow restarted also with the power
The most common problem encountered when using a USB device is the power source-the power supply is insufficient. to effectively solve the fault of insufficient power of the USB interface, this article specifically summarizes some countermeasures, I hope it will be useful to you!
How to identify USB Power InsufficiencyGenerally, when a USB device is inserted into a Windows 2000 or later system, it can be automatically recognized by the system and
Mouse, keyboard, flash memory, mobile hard drive, USB Desk Lamp, fan, who has no more than seven or eight USB devices at home, are embarrassed to tell people that they have bought a computer at home. However, if there are so many devices and the computer port is not enough, power supply is a problem. Therefore, buy an active USB hub to free the external USB device from the USB port power supply restrictions
