For switching high-powered loads from a microcontroller, or for switching AC loads in general, most of us will reach into the ...

The easy way to measure high AC currents is to use a clamp meter but these are generally quite expensive and cost several hundred dollars at a minimum. Add-on clampmeter adaptors can work well but ...

When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

Figure-1 shows the schematic diagram of the device. P1 is used to connect the 220V-AC input and the ON/OFF switch to the circuit. C1 is used to reduce the AC voltage. The value of the C1 also ...

Pulse Electronics Corporation introduces its new Sidewinder™ AC current sensors. Sidewinder products differ from traditional current sense transformers because they do not need a core. This makes them ...

A common data logging application is measuring voltage or current flowing into or out of a piece of equipment, such as a user monitoring current in solar cells, inverters, or storage batteries. These ...

As the story goes, the rock band AC/DC took its name from a label on an old sewing machine in the Young brothers’ home. It must have meant that the machine could run on either alternating-current or ...
