NT2140 discrete AC I/O module has been added to the BusWorks NT Ethernet I/O family, and provides six 120 V or 240 V AC ...
After a major water leak flooded my home, I realized alerts alone weren’t sufficient—I needed automatic shutoff. This project combines a hacked Gröhe Guard system, an Arduino Nano, an ESP32, and the ...
Optocoupler biasing is a critical yet often overlooked aspect of isolated SMPS design. Ensuring proper biasing of both the LED and phototransistor sides of the optocoupler is essential for maintaining ...
Abstract: This paper presents a new DC-DC buck converter with an optocoupler as a switching device. Conventional buck converters use a transformer for galvanic isolation for the PWM signal, which has ...
Abstract: Proton-radiation test results for new optocoupler technologies are compared with those of older optocouplers. The new devices are far more resistant to displacement damage effects and have a ...
