Water tank overflow is a common problem which leads to the wastage of water. Though there are many solutions, like ball valves which automatically stop water flow once the tank gets full, electronics ...

Batteries come with a certain voltage limit and if the voltage goes beyond the prescribed limits while charging or discharging, the life of the battery get affected or reduced. Whenever we use a ...

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 ...

DeadEasy is a switchboard mounted, voltage indicator that includes a self test function. This 3 phase indicator is primarily used to verify safety isolations as part of a lockout procedure. A true ...

The ICs support 3 to 5 LED battery displays, reduce power use, need no microcontroller, and offer two modes for battery indication. ABLIC launches Voltage monitoring ICs for driving 5 and 4 LED ...

Here is a simple, versatile circuit which indicates the level of water in a tank. This water level indicator alarm consists of twelve levels. The circuit sounds an alarm when the water is below the ...

This LED DC voltage indicator circuit is a voltmeter, rather than simply a battery tester. As such it may measure voltages as low as 3V. It utilizes venerable LM741 operational amplifiers applied as ...

Foremost Electronics is pleased to announced the availability of the MARL 671 Series of High Voltage LED panel mounted indicator suitable for fixed and portable equipment and is internally potted ...

Abstract: This paper proposes real time voltage instability risk indicators based on a reliable identification, through bus local phasor measurements at fast sampling rate, of the Thevenin equivalent ...
