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 ...

LEM is aiming at rail traction and industrial applications with a series of isolated voltage sensors for ac, dc and pulsed use. DVC 1000 series sensors are panel-mount and measure 29 x 51 x 89mm – 131 ...

Avago Technologies introduces a new family of optically-isolated voltage sensors, which are optical isolation amplifiers based on sigma-delta modulation that is specifically optimized for voltage ...

Isolation in this case, is from the mains, and it transpires that finding something that will do the job safely is tricky. Three isolated Hall-based current sensing modules are easy to obtain, as far ...

The ACPL-C87B/C87A/C870 voltage sensors are optical isolation amplifiers designed specifically for voltage sensing. Its 2V input range and high 1GΩ input impedance, makes it well suited for isolated ...

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 ...

Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...
