I've just managed to pull apart another broken car amp, and I've pretty much struck gold as I can use the SPMS from it.
Now, I've tested it at different voltages...
12v in = 26v out
13v in = 28v out
14v in = 30v out
15v in = 32v out
16v in = 34v out
I've rounded the values a little but you get the idea...
Now the amp module I want to power (41Hz AMP9) says the max voltage is 26v... So I'm guessing the 30v will be too high for it...
Now, I may try a diode or two on the input to bring the voltage down a little, or even lose a turn on the secondary windings, but I need to know if my car's electrical system is ever going to go over 14v at all?
I've tried searching, and found mixed results, and no definite answers.
I'm tempted to treat 15v as the absolute max....
