In LEDs heat and high currents hasten the dimming process which can lead to unreliable operation in LED-powered optocouplers. Some simple and straight-forward analysis will keep their light shining ...

Optocouplers are used extensively for high-voltage isolation and electrical noise rejection – two essential requirements for transmitting correct information between different voltage potentials ...

Here is a simple circuit you can use to measure the attack and release times of photoresistor-type optocouplers that often find use in audio compressors or volume-control circuits (figure). The design ...

Optocouplers are devices that transfer electrical signals via light waves. They're appropriate for discrete-motion applications in industrial environments. Through light waves, optocouplers transfer ...

Standex-Meder Electronics announces its new ATEX optocoupler for intrinsically safe circuits. Standex-Meder Electronics announces its new ATEX optocoupler for intrinsically safe circuits. The ...

Switching power supplies, operating directly from input power lines, are generally required to have their outputs galvanically isolated from the input, in order to reduce the danger of electrical ...

Over the years we’ve seen several attempts at adding Internet connectivity to the lowly wired doorbell. Generally, these projects aim to piggyback on the existing wiring, bells, and buttons rather ...
