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 ...

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 ...

HD Electric Co.'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 up to 500kV. HD ...

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 ...

Up to now, this battery level indicator design was limited to 12 & 24V applications. In past circuits, the use of fixed resistors greatly simplifies setup. However, fixed resistors resulted in ...

This overvoltage detector can be connected to any dc power source (Fig. 1). Its purpose is to provide a visual indication of when the voltage exceeds a preset value, which may range from around 3 V to ...

For use with voltages from 5V to 28V Moisture seal allows for outdoor applications Mounting hole size of 14 mm (0.551 in.) The all-in-one CNX 714FV Series 14-mm indicator offers the company’s FlexVolt ...
