I am more of a digital guy, but I am trying to make a replacemnt controller for my snow maker machine I have. The controller is very simple and takes in 11.3V from the snow maker, and then spits out 11.3V when off, and a range of 1.4V - 6.6V when on depending on how hard you want the snow blower to blow (by turning a 90k pot). The circuit is simple and I basically understand it and can recreate it, EXCEPT for the transistor.
The transistor is labeled as a C945 P228C which appears to be an old NPN transistor. I have some 2N2222 lying around and it seems comparable, but I can't quite tell. How do I know if it will be OK (some particular value I should look at?)?
There isn't really any fast switching that needs to be done and as far as I can tell the voltage dividing is being handled by the pot, so I figure as long as the transistor can handle the voltage levels, I should be pretty close. Am I way off in this thinking?
