A novel supply voltage monitor which uses a LED to show the status of a power supply. This simple and slightly odd circuit can clearly show the level of the supply voltage (in a larger device): as ...

February 1, 2012 -- HDE's DVI-100 and DVI-500 Series Digital Voltage Indicators are designed to be used on both transmission and distribution systems in overhead and underground applications. The ...

Medium-voltage indicators (2-43 kV) keep workers away from voltage and lets them know if there’s voltage or not. The indicator is a single-phase device mounted onto each phase of a power bus. Energy ...

There are many applications where the accuracy of a digital or analogue (bar graph) is not required but something better than a simple low/high indicator is desirable. A battery charge level indicator ...

HD Electric Co.'s DVI-500 Digital Voltage Indicators are a new addition to the Digital Voltage Indicator line. The DVI is a direct-contact, compact instrument designed to read the voltage on a ...

Avoid unexpected shutdowns in your 9-V-powered projects with this simple low-battery indicator circuit. It uses just a ...
