Enhancing motor-drive apps with added safety, the ACPL-785J isolation amplifiers include both short-circuit and overload detection and allow direct measurement of motor phase currents in power ...

Isolation amplifier is a device that electrically isolates two circuits. In another terms, there is no direct electrical connection between the two circuits. Isolation amplifiers are used in a variety ...

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 ...

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 ...

The isolation amplifier circuit of Figure 1 is simple but accurate. With the values shown it converts 0 to 5V DC or low frequency signals with unity gain, but you can adjust the gain by changing R4.

One of the more difficult problems that designers may face is trying to isolate precision analog signals in an extremely noisy environment. A good example is moni- toring the motor phase current in a ...
