This compact mains voltage sensor is intended to monitor and signal to another circuit, for instance a microcontroller, about the presence and/or absence of the ac mains voltage. For this task, a ...

The shocking truth is that accidentally coming in contact with ac-line voltage is no fun and, on occasion, can be lethal. Following the philosophy that it should do its utmost to keep all of its ...

Electric motors that are either poorly maintained or which lack the proper electrical protection are the second greatest cause of electrical fires. So says the Factory Mutual Research Corp., a ...

Designed specifically for high-voltage sensing, a new generation of optically isolated amplifiers make monitoring and system protection circuits more accurate and easier to design. These iso-amps can ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...
