Alan Martin, Engineer Extraordinaire, once told me, “You never regret adding isolation between your circuits.” While he was speaking in the context of power supplies, the same goes for isolating ...

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 ...

PARIS — The OPI127-032 high voltage optical isolator from Optek provides more than 16kV isolation while meeting the IEC requirements for 32mm creepage. The Photologic optically coupled isolator is ...

Traditional computers are fast, but nothing like the speed of light—at 186,000 miles per second, you can crunch numbers awfully quick. That’s a big reason why optical photonics are being used for ...

A new level of optical isolation necessary to advance on-chip optical signal processing has now been demonstrated by researchers. The technique involving light-sound interaction can be implemented in ...

Insulated-gate bipolar transistors (IGBTs) require full protection to avoid damage and failures resulting from conditions such as short circuits, overloads and overvoltages. The protection is key to ...

For integrated photonics to take off, light signals zooming around optical chips must be successfully isolated from one another. Scientists at Stanford University have now designed a miniature one-way ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

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 ...
