Have you ever needed to power a 12-volt relay in a circuit but only had 6 or 9 volts available? This simple circuit will solve that problem. It allows 12-volt relays to be operated from 6 or 9 volts, ...

What's a designer to do when challenged with a switching application that requires handling up to 70 kV? These applications are not as rare as one may think. In fact, a broad range of applications in ...

If you've ever wondered how electronic devices manage to control circuits with precision and safety, you're thinking about the magic of relays. Relays act as the unsung heroes in many of our devices, ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

Mechanical relays, contactors, and switches control the flow of electricity by the mechanical action of two conducting elements. The physical contact of two conducting elements creates a path for ...

The proper selection of 3-phase solid state relays for motor control application depends not only upon a comprehensive understanding of 3-phase SSRs, but also of the 3-phase power system and typical ...
