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 ...
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 ...
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 ...
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.
