oops sorry for the inconvenience..this is my 1st thread..so please be kind...What supply voltage to power the circuit?
What kind of output?
What load is it switching?
How many Amps is it switching?
How precise does the trip point need to be? 2+-x mV?
How temperature stable does the trip point need to be?
What impedance does it have to present to the input voltage?
You should put a lot more effort into specifying what you are asking for instead of forcing us to play twenty questions...
sorry for the inconvenience...this is my first thread.. so please be kindThe Completed Projects Forum is for Completed Projects only. It is meant to allow members to show plans for projects they built so other members can duplicate them if desired. Your thread does not belong in this forum, and was moved here.
hey...thank you..let me try this outI assume that by "solenoid", you mean a 12Vdc relay with a coil resistance of ~120Ω.
Here is a simple adjustable circuit:
