This AC power switch circuit senses the presence of AC current in one outlet of a multi-outlet power strip and switches power to the remaining outlet(s). It utilizes a current transformer, single ...

The circuit was designed to provide a voltage over and under the specified value with the use of a switch that will be operated by a relay. LM741 – a general purpose single operational amplifier with ...

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 ...
