Overview
In spectral measurement, photomultiplier tubes (PMT) and charge-coupled devices (CCD) are often used as photoelectric converters. PMT is used in slow-changing, high-precision spectral...[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]
At present, a large number of cooling tower fans, speed fans and special fans are in use in petroleum, chemical, pharmaceutical, metallurgical and other enterprises. Some fans have no monitoring in...[Details]
The most important components of new energy electric vehicles are power batteries, electric motors and energy conversion control systems. The power battery must achieve high performance such as fas...[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]
Synchronous buck designs are becoming increasingly difficult, and the selection of suitable ICs is becoming quite narrow. This Design Idea combines a current-mode PWM IC used in a flyback regulator...[Details]
