HI,
I have made a circuit using LM339 comparator Ic. I am having an issue. When I supply comparable power at 6 7 terminals with 24 volt Power supply my circuit does not work. But if I apply power using 9 volt battery it works Ok.
It also works if I use a 10k resistor in series with the positive terminal of 24v power supply system. Guide me how can i use 24 volt for this system. As i am going to activate a relay at 23.9 coming from a 24 volt battery system or less volt at one side and other at reference 24 volt by power supply.
