I have been working on a low voltage cut out switch and have had extensive help here on this forum. With the guidelines I think I have made progress.
I am wanting to switch off a relay through a BC547 when the voltage drops to a Preset level.
On the circuit I have been using the voltage between the cathode and ground stays at 2.7 Volts as I reduce the voltage it suddenly switches to 1o.6 Volts This is when the load must be switched out.
I was using a IRF9540 but it never switches off and I have no idea why. Thus wanting to try another circuit.
The circuit I was given is on a post of mine titled low voltage cut out
