There are many ways to measure current. The traditional methods of taking current measurements by inserting a shunt resistor or using a current transformer have the disadvantage of having to break the circuit conductor. For current transformer there are also models that can be installed in place without cutting the cable (more expensive and usually →
Websocket is a promising technology for more advanced web applications. Websocket allows to make a continuous two-way connection between the application software running on web browser the software running on server. WebSocket represents the next evolutionary step in web communication compared to Comet and Ajax. The WebSocket standard (when it gets ready and widely supported) →
As we all know, a good LED could last very long up to 50,000 hours with with a good heat sink. But how is the LED driver electronics life? For common LED drivers there is at least one component is very weak. It’s the electrolytic capacitor. High Bay LED Lighting Driver Heat Dissipation Temperature Test →
Why modern high tech electronics fail? Too often the reason for that is electrolytic capacitor failure. I have had a quite high number of electronics that has failed by this reason after few years of service. I have had a quite number of devices failed by capacitor: PC motherboard, PC graphics card, set-top-box, DVD player. →
The most common reasons that modern digital electronics devices fail seem to be a bad electrolytic capacitors. Bad electrolytic capacitors cause frequent failures of switch mode power supplies. It seems power supplies are often the weakest link in many modern electronics devices. Since there is tremendous price pressure on PC’s and other consumer electronics devices, →
