According to the Industrial Technology Research Institute of Taiwan, due to factors such as the oil crisis and global warming, the issues of energy conservation and environmental protection have at...[Details]
Since AC mains power may experience power outages, voltage sags and surges, continuous undervoltage and overvoltage, and frequency fluctuations during supply, these factors will affect the continuous ...[Details]
Against the backdrop of global warming, energy conservation and emission reduction have become a global hotspot and focus, which has also sounded the clarion call for the take-off of the LED lighti...[Details]
A few days ago, I bought an 8LED flashlight in the market (the flashlight uses No. 5 batteries). Because I had other things to do, I didn't pay attention when purchasing it. When I got home and use...[Details]
1 Load Regulation
Changes in power supply load will cause changes in power supply output. When the load increases, the output decreases, and vice versa, when the load decreases, the output inc...[Details]
1 Introduction
Washing machines are an indispensable household appliance in the home, and they are developing very fast. Fully automatic washing machines are favored by everyone because of their con...[Details]
There are many types and styles of digital voltmeters in design and development. Traditional digital voltmeters have their own characteristics. They are suitable for manual measurement on site. Tra...[Details]
In recent years, the application of single-chip microcomputer systems in the field of industrial measurement and control has become more and more extensive. However, for industrial sites with harsh...[Details]
Current sensing in automotive applications includes controlling the current through solenoids and injectors. For example, during diesel injection, we rapidly increase the current to the induction i...[Details]
