American Aerospace Controls (AAC) of New York, which supplies AC & DC current, voltage, power and frequency transducers, has seen its DO-160E qualified AC current level detector specified for ...
The circuit in this Design Idea detects short-circuit faults or excess-current conditions in line-operated equipment, such as a UPS (uninterruptible power supply), across an isolation boundary. If the ...
You can use a simple battery-poweredcircuit to detect whether anac-mains wire is live without makingany electrical contact with it. The circuituses a CD4011 NAND gate’s highinput impedance to sense a ...
Residential and commercial circuit breakers face three major challenges: detecting arc faults reliably, reducing false trips ...
Nisshinbo Micro Devices has come out with a digital earth leakage current detector IC designed to enhance the safety and reliability of electrical systems by integrating advanced overvoltage and DC ...
