LED Blown AC Fuse Indicator Circuit Diagram
This circuit monitors a AC fuse. In this circuit, the LED indicator shows whether or not the fuse is blown.
|D1||2.7V 0.5W Zener Diode|
|D2||5.6V 0.5W Zener Diode|
This fuse indicator circuit makes an LED light up if a fuse blows, this gives a quick indication if the fuse has open and the LED can be sited on the front or rear panel saving time when fault finding.
This blown fuse detector will work with a wide range of AC supply voltages from 30V to 300V and good for use with few milliampere to many amperes fuse.
Don’t touch any component, when circuit is connected to the AC power.
